FAQs

Under the New Zealand Building Code, new homes and additions to existing homes must be insulated to a minimum standard, depending in what area of the country you live in. 

However, it is better to install insulation with higher protection (R-values). This means you will enjoy greater comfort and long-term energy savings for only a small extra cost.

A R-value is a rating which measures how well insulation can resist heat flow. The R-value of an insulation product depends on the type of material, its density and thickness.

Tiny air particles trapped in the insulating material resist the movement of heat. The higher the R-value, the better the insulation is at reducing heat flow and keeping heat in (or out).

Pink® Batts® insulation offers you many benefits:

Comfort - Pink® Batts® insulation keeps your home at a comfortable and healthy temperature, year round. It also helps to dampens noise from within and without, making your home much quieter. 

Cost savings – With Pink® Batts® insulation, you spend a lot less on your energy bills. An un-insulated home uses 30% more energy to heat than a fully insulated home. 

Sustainability - Pink® Batts® insulation is made mostly of recycled glass so it leaves a light footprint on the environment.

Product safety – Pink® Batts® insulation won’t catch fire or melt easily. It is also proven to be safe for humans, so you can install it in your home with confidence.

Protects our future - By using less energy, you’re not just cutting your power bills, you’re also helping New Zealand to reduce greenhouse gas emissions.

If your house was built before 2000, you are eligible for Government funding to install insulation in your home. This means you can get up to $1,300 towards the cost of ceiling and under floor insulation if you have a pre-2000 home.

Fitting ceiling insulation is reasonably straightforward.  However, installing underfloor and wall insulation can be more challenging.   

If your DIY confidence extends only to the easier installation projects, you can adopt a mix and match approach: do the ceiling installation yourself and call on the experts for the rest of the job. That way, you also benefit from the Government’s ENERGYWISE™ grant for the professional part of the installation.

Pink® Batts® wall insulation and Pink® Batts® ceiling insulation are trimmed to different sizes and shapes, depending on whether they are made for wall or roof spaces.

Pink® Batts® insulation is trimmed to conform with standard New Zealand truss and joist sizes. Pink® Batts® ceiling insulation is 1220mm x 432mm and Pink® Batts® wall insulation is 1140mm x 580mm.

You can use Pink® Batts® ceiling insulation in your home’s walls if you trim it to the correct size and it fits in the cavity neatly ie without gaps or being squashed.

Pink® Batts® insulation is safe for your home. It is made only from glass wool, which is proven to be safe for humans. 

Even if you inhale glass wool fibres into your lungs during installation, most fibres dissolve inside your body and disappear quickly.

Pink® Batts® insulation is non-combustible, which means it won’t catch fire or melt easily. Its resin backing is also non-flammable. However, some types of insulation will burn if exposed to fire.

If you want to reduce noise, particularly specific noise such as a flushing toilet, it’s best to use the insulation designed for this purpose. The Pink® Batts® Silencer® range offers acoustic protection for your walls. You can also choose Pink® Batts® Silencer® MidFloor to dampen sounds travelling between floors.  

Pink® Batts® thermal insulation will partially reduce noise but it doesn’t have the same ability to dampen sounds as acoustic insulation.
