poorly insulated roof Living in a poorly insulated house can be dreadful. Houses that are hot and humid in the summer, or bitterly cold in the winter are usually houses with poor insulation. Here are 5 signs that your house may be poorly insulated and some suggestions on how to resolve this issue.

1. You can’t get any relief from heat and humidity during summertime.

This is a problem that many New Zealand homes with poor insulation face. Older homes with metal roofs and poor ceiling insulation often creates an oven like effect in your home. In this situation, your home interior temperature starts to super heat and it can be very hard to try and cool. You’ll know you have a problem when in the middle of a hot summer’s day, it’s cooler outside than inside your home. The best way to fix this issue is to have an assessor come visit your house and give you a home insulation report and consultation for improving the insulation standards inside your home. Check out our recent article if you’re interested in learning more about the basics of thermal insulation.

2. There’s condensation on my windows in the morning and the house feels damp

You should never be waking up to weeping windows or wet carpets. Condensation may seem a natural phenomenon for an older house, but it isn’t. Condensation or dampness is a primarily indication that there is something wrong with the insulation and you may need to fix this. The best thing you can do is have an insulation assessment done for your house. An expert will come out, assess the insulation situation and they will provide recommendations on what can be done to resolve the problem.

3. You can’t get rid of drafts in your house

Is your house so drafty it always feels like there’s an open door? Drafts can be caused by several problems but usually indicate there are gaps in your home’s thermal barrier where air can enter and escape. Damage to your exterior cladding or gaps around windows and doors are know to cause drafts. Older homes suffer with this problem so checking if your insulation has deteriorated is important. Uninsulated walls can add to this problem. Thankfully, there are wall insulation systems available in the market today that are able to fix this problem without having to remove your wall linings. Talk to our team to discuss the insulation options for your home.

4. Your floors are always cold

Older New Zealand homes built on piles left floorboards quite exposed to the outside climate. Coastline homes or houses built on sloping sections may experience this problem. If your floorboards are usually cold, it means the outside air is getting in through the floor of your house and it’s an indicator of poor floor insulation. Specialised insulation blankets installed on the underside of your floorboards will resolve this issue. These insulation blankets help complete your home’s thermal barrier and will help make your home much more livable.

5. Mice or bugs on your property can be a sign of damaged or poor insulation

Are you regularly finding mice, rodents or bugs invading your home? These critters are quite damaging to any existing insulation. This is particularly likely if you live in an older house. The best thing to do is give us a call and we can come out and do an insulation assessment. If necessary we can repair or replace your insulation which will help keep those unwanted critters outside the home.


If you are experiencing any of these issues or suspect you may be living in a house with poor insulation. We can providing a free home assessment to help provide recommendations on how you can improve your homes insulation.

Warm Your Home

It’s starting to get colder and if you may be starting to wonder how to warm your home this winter! Colder weather results in colder homes, which can affect our health. It’s important to start thinking about how to protect you and your family from cold’s, flu’s, and other nasties this winter – including how to keep your home warm to help reduce the risks of catching those winter woes.

Here’s some top tips to warm your home for this winter.


While many winter days may be rainy and cloudy, we often see winter days with the sun out and shining. Even on cold days, the sun is still warm. So once the sun is up, capture in that free heat by opening up your curtains and letting that sunshine in before you leave your house in the mornings.


Like opening up your curtains during the day, it’s important to shut them as soon as it gets dark. Curtains act as another layer of insulation to keep warmth and dryness in your rooms. If you don’t have quality curtains, and are thinking of replacing them – think about getting ‘thermal’ curtains which are best at keeping the warmth in.


Every room has a warmer and colder point depending on where your windows and doors are positioned. You will feel warmer if you position yourself closer to the inside of the house, because your cold, external walls are further away. Or perhaps your sofa is currently near a window. In this case, you may feel warmer if you move your sofa to a position in the room where it’s further away from your windows and doors. Think about practical ways you can rearrange your furniture to maximise warmth within your home.


Ever noticed that cool draft in your home that comes out of nowhere? That’s often due to leaks through windows, doors, basements, and other spots in the house. Walk around your home to figure out where that draft is coming from, and seal it. Windows and doors are best solved with spray foam insulation, and other holes can be blocked by caulk.

Drafts in the home can also be a sign of an uninsulated house – read our recent article about the signs of a poorly insulated house.


Architecture Now states that 10% of heat is lost through wooden floors. If you’ve got wooden floors in your home, it’s a good idea to make use of rugs to keep your rooms warmer. If you want to go the extra mile, opting for carpet can do wonders in making your home feel warmer and cosier.


It’s estimated that homes without sufficient insulation lose 42% of its heat through the roof, 24% through its walls, and 10% through the floors. That is a huge amount of heat loss! While you may think your home is insulated, we often find customers don’t realise they’re missing wall insulation, or that their ceiling insulation has degraded over time.

To ensure your home is warm this winter, it’s time to assess your current insulation. One of friendly team can help assess the insulation in your home, and make necessary adjustments to improve your insulation. Contact us today to learn more!

Absolute Energy is one of our local Kiwi business success stories. Over its 20 years in business, the company has grown into one of the country’s most trusted insulation service providers thanks in part to the inspirational leadership of local entrepreneur and business leader Paul Brockie. Read on or have a watch the story below.

We sat down with Paul who talks about the 20-year journey that led him to build one of the most recognisable brands in Nelson.

“Looking back at our journey from early 2000 to now, Absolute Energy just started off as an idea that we could really make homes and people’s lives better. At that point, we were still a building company and I actually ended up using our builders to put insulation into homes. To be honest they probably weren’t very happy about that. It really started to grow, and I decided we really needed someone specialised to help me do this project.”

As Paul reflects on the journey, he underscores how important key people were to the business’s success.

“Tanya has been with me since 1999. She was working for me in the building business and came across as my first staff member and she’s still with the business today. Soon after, we employed Gideon as an installer and with the help of my dad, they started touring around the top of the South Island pumping insulation into people’s homes.”

“While we are a family business, the whole team culture is like that of a big family. It’s important to me that everyone is looked after and feels valued and if they’re not happy, I’m not happy.”

There were some key moments that propelled the business forward and a couple of contracts and tenders that the business successfully won which became the backbone of the company’s growth.

“The very first contract we won was with Network Tasman to insulate homes across Nelson/Tasman. Nick Clark who was the manager of this contract came on board and together we started building a small team and developed a cool funky brand.”

“Soon after we were successful in winning a much larger contract with Nelson City Council which saw us insulate many homes across Nelson alone. We just started steadily growing, taking on more staff and equipment and the difference we were making was just awesome.”

Following the initial success of the business, Absolute Energy became a provider for EECA and the Heat Smart program. This relationship has remained strong since 2009 and together they’ve been able to continue to insulate many thousands of Kiwi homes.

“Today, we’ve insulated 20,000 homes over the top of the South, and we’ve expanded into Dunedin and Queenstown. It’s been exciting to see the growth and it’s still exciting today!”

Paul describes the thought process around the development of the Absolute Energy brand. To him it was so much more than just an insulation business.

It was important to Paul to have a strong visual brand. He wanted to have a brand that really stood out and was recognisable across vehicles, road signs, apparel, and right down to business cards and pens.

“I thought, what can we do that’s going to capture people’s thoughts around energy savings………. absolute energy.”

I’ve had the privilege of talking with numerous clients, partners and staff over the last few weeks. They have all shared their experiences of working with Absolute Energy. It’s clear that the core their success is the motivation to actually make a difference in people’s lives. Absolute Energy are passionate about giving back and this sentiment extends into the community. They currently sponsor and support many local individuals and community groups across the region.

Paul wraps up by reflecting on the fact that Absolute Energy has become a generational business. His son Troy is already starting to take over the day-to-day operations.

“The future of Absolute Energy with Troy taking the reigns is exciting. This brand has got so many good things and great people going for it. The brand speaks for itself, and people trust us and we’ve got an incredible future ahead.”

Most of us that live in older homes will have some insulation but insulation standards have historically been poor. Research has shown that older homes are poorly insulated homes, and this can lead to many respiratory and health issues. A well-insulated house really does help create a healthier, warmer, dryer and more energy efficient home. Thankfully, the government know this too. In recent years they have provided funding to make well insulated homes more affordable and accessible.

Thermal Insulation is an important part of every house and helps keep your house warm in the winter and cool in the summer. To understand how thermal insulation actually works however we need to take a few steps back and take a look at some of the science around heat transfer.

What is heat transfer and how does it work?

The first thing to know about heat transfer is that heat will always try and move from the warmest areas to the coolest ones, seeking a balance. In the home, the greater the temperature difference, the faster heat will try and flow into the coldest area. Research tells us that the three methods of heat transfer are conduction, convection, and radiation. Let’s have a quick look at these.

Heat transfer through conduction

Conduction refers to heat transfer at the molecular level within a certain material. The material might be a solid, gas or liquid but heat transfer happens when there is a temperature difference between two materials, and they come into contact with one another.

Heat Transfer Conduction
Molecules are agitated when heat is conducted from one particle to another. The rate of heat transfer will increase or decrease depending on the difference in temperatures between the two materials, and the thermal conductivity of these materials.

Heat transfer through convection

Fluids, such as air or a liquid, travel away from their source when heated. They carry thermal energy with them. This type of heat transfer is called convection. The fluid above a hot surface expands and becomes less dense as it rises.

Heat Transfer Convection
A good example of convection heat transfer is to look at the hot air balloon. A hot air balloon rises because warmer air is less dense than cool air. Since the balloon is less dense than the air around it, and it becomes positively buoyant and rises.

Heat transfer through radiation

The final heat transfer method is through radiation. In this example heat actually travels through light, either as infrared light or other types of electromagnetic waves. The energy is freely transferred through a direct line of sight or through translucent materials.

Heat Transfer Radiation
A great example of radiation heat transfer is simply looking at sunlight. As sunlight impacts a surface it starts to heat up. If you’ve ever stood barefoot on a sandy beach in the middle of a hot summer’s day you’ll know what I mean here.

Different materials act differently to radiation heat transfer which is why some surfaces get hotter than others in direct sunlight.

So I understand heat transfer, how does this impact my home’s thermal insulation?

Really only convection and radiation heat transfer directly impact the home. Adding thermal insulation to your home’s roof and wall cavities combats creates a barrier that helps protect your home from this.

Insulation is made from materials with a high thermal resistance rating. This rating is measured by what we call an R-Value. The higher the R-Value, the stronger the thermal barrier between the inside and outside of the home.

So to better understand how thermal insulation works, let’s look at two different scenarios.

Thermal insulation for radiation heat transfer

Let’s say you’re in the middle of summer and your home has no thermal insulation in the roof. Radiant heat from direct sunlight at the hottest time of the year will cause the home to heat up.

This radiant heat will quickly pass straight through the roof and walls, which causes the inside air of your home to heat, and creating an oven-like environment inside.

Adding thermal roof insulation and wall insulation means helps stop the radiant heat passing through these surfaces and preventing the house from heating up as quickly.

Thermal Insulation for convection heat transfer

Let’s say you’re in the middle of winter and again there’s no thermal insulation barrier in your roof or walls. Naturally, you’ll put a heater on to try and warm the room. Unfortunately, because of the large temperature difference, the heat will quickly escape from the house however it can make it incredibly difficult and costly to keep the house warm.

After adding a thermal insulation barrier, heat will no longer be able to escape the house. This means that the heater will be far more efficient at warming up the home. It also means the heat will remain inside for longer, resulting in a far more energy-efficient home.

Changes to H1

In this article, we discuss the upcoming changes to H1/AS1 in the New Zealand Building Code and what that means for the insulation levels required in your home moving forward.

You’ve probably seen from the media that the building industry has been under incredible pressure over the past 2 years. With interest rates at all-time lows, the demand for building and construction services has boomed to levels never seen in New Zealand. This has meant that manufacturers have been producing building materials in record quantities however this still hasn’t been enough to keep up with the demand. To add to the chaos, COVID-19 has impacted supply chains, creating issues with accessing the raw materials necessary to manufacture building products. This perfect storm has pushed the price of building up more than 30% during the same period.

During this time the Government has also been focused on improving the building standards for the industry. In particular, the government has focused on improving energy efficiency and improving this by increasing the minimum insulation/R-values as a control of airflow, solar heat gain, hot water systems and artificial lighting. In doing so, MBIE (Ministry of Business, Innovation & Employment) has announced changes to H1/AS1 which will apply to all new homes from 2nd November 2022.

What are the changes to H1/AS1 and what does this mean for new homes?

The major update has been the creation of 6 climate zones throughout New Zealand. These Zones will determine the new minimum insulation standards required from your home.

Changes to H1 - New Climate Zones

The table below shows the increase in minimum R-Vales across the new climate zones.

Changes to H1 - Insulation Table

Ceiling insulation will increase to a minimum of R6.6 across all zones and underfloor insulation will increase to R3.0. Standards for wall insulation will also slightly increased to R2.0.

Across all zones, the minimum insulation levels will increase across ceilings walls and floors. Insulation for window glazing has also increased. Homes meeting these new standards will be approximately 40% more energy-efficient. The improved thermal efficient reduces the overall energy needed to heat and cool your home.

Insulation and Joinery manufacturers are rapidly working to design and re-engineer their product ranges to ensure builders and construction companies can meet comply with the new standards by the November 2022 deadline.

Future proposed insulation changes to H1/AS1 Acceptable Solutions.

MBIE is expected to announce further changes that wall thicknesses in standard residential homes. These proposed future changes will increase wall thickness from 90mm to 140mm. MBIE will wait for supply chain pressures to reduce before introducing this change.

Homes with a 140mm wide wall cavity would require a much higher level of wall insulation, and many home builders are actively looking at adjusting their designs in anticipation of these future changes.

How do these changes affect me?

If you have an existing house, you don’t need to do anything however all new homes will need to comply with the new requirements.

As a landlord, you may also want to consider upgrading your homes insulation to ensure they need the new standards.

If you have questions about the changes to H1/AS1 we’d be happy to chat. Feel free to contact one of our sales consultants so we can discuss your specific requirements.

Batts vs Blown Insulation?

One of the question’s we are regularly asked by customers is which type of insulation product they should use in their home. With so many options out there it’s easy to get a little confused. In this article we’re going to specifically look at batts vs blown insulation and discuss the differences between these two products.


An overview of Batts Insulation

Batts Insulation

Firstly, Batts Insulation is generally a fibreglass or mineral wool-based insulation. They are available as manufactured rolls and also pre-cut industry sizes.

Batts have typically been used as the primary form of insulation when constructing a new house. This is since they are quick and easy to install at the framing stage of a build while the linings are off. Sometimes installers choose to install batts in the roof but this is rare due to its low thermal rating. Batts insulation is much harder to install as a retrofit insulation product because of the need to remove the houses linings to install.

One of the down sides of batts insulation is that it typically has lower R-Values that other forms of insulation. The general R-Values of batts insulation rage between R1.8 and 2.8. While this is usually ok for a wall insulation product, in New Zealand most roofs require a higher thermal insulation value.

Recently the government announced changes to the Building Code which will require much higher thermal performance levels than previously required. You can have a look at the new Acceptable Solution H1/AS1 document here. These changes come into effect from November 2023 and will mean that most batts products currently available will not meet the new standards.

The good news is, manufacturers around the country are looking at their product ranges and starting to introduce new Batt products with higher thermal values however these products are likely to be more expensive than traditional batts products.


Blown Insulation – A great product for insulating existing houses

Blown Insulation is a loose-fill or granular substance, made from specialised recycled materials. It’s a perfect insulation product which can fill up gaps often left by batts insulation.

Installing blown insulation in a new build is more complicated than a batts product. Blown insulation has higher performance levels than batts products and designers use this when developing high performance and passive home builds. This market is rapidly developing in New Zealand, and we could see this become more common in the new build sector, especially with the upcoming government changes.

The typical use for blown insulation is when adding retrofit insulation to an existing home. It’s particularly useful as wall insulation and can be easily added without having to remove the home’s linings. For your roof, installers blow insulation across the top of your ceiling and rafters. In the walls, installers blow insulation through small holes in the walls. Installers will repair the holes after installation and leave the home without damage.

Blown insulation has higher installed densities than batts which is one of the main product advantages. This gives higher R-Values and better thermal performance which is particularly useful in the South Island.


Our verdict on batts vs blown insulation?

So when weighing the choice between batts vs blown insulation, the reality is that both these products have a place in the market. Each home is different and it’s important that you choose the right product for the type of house you’re insulating. Absolute Energy provide a free home assessment and can provide recommendations and advice about selecting batts vs blown insulation. Contact us today to book your free home assessment.

Insulation Removal Turbovac

Over time, home insulation tends to deteriorate and break down making it less effective. Insulation damage can be caused by several factors including rodents, damage to your home and temperature fluctuations. Older insulation products are also known to be less durable than modern ones. Insulation removal and replacement is required to solve these issues.

Here are a few of the symptoms that might be warning signs that the home has poor or old insulation.

– Houses that are hard to heat or cool
– Mold growing in the corners of walls and windows
– Condensation on the windows
– General dampness in the home
– Drafts in the home

Issues with poor insulation can lead to a number of serious health issues so if you have a general sense that your home has poor insulation, you may want to consider Absolute Energy’s Insulation Removal service.
