Wall Insulation Q&A

Kiwi homes are notoriously cold and damp – so investing in the correct insulation for your home can be one of the best investments you’ll make. Not only will insulation keep your home warm in the winter and cool in the summer, there are a number of other benefits – including a healthier home and of course savings on your monthly power bill. CosyWall Insulation has been around for over 15 years, but what exactly is it? Check out the Wall Insulation Q&A session below:

In a nutshell

The CosyWall Insulation system is a multi-purpose product designed to provide effective thermal wall insulation and soundproofing to your home. In most cases wall insulation will complete the homes thermal envelope. The results are amazing. Faster to warm the home, stays warmer for much longer, less noise from the road and neighbours.

How you get the insulation inside the walls without destroying my walls? And how long it’ll take to get the job done!

Most installs can be completed within a day or two. And, of course we make sure everything is clean and tidy before we leave.

What about the mess?

Most houses in New Zealand have a gap – know as a cavity – between the interior walls and the exterior cladding and it’s this cavity that allows the heat to escape. We fill this cavity with an insulating material that will help retain the heat. The insulation is literally blown into the cavity by our team of professionals who drill small holes into the walls of your house – exterior usually, but if you are thinking about refreshing your interior décor we can also do it internally too. Either way we will then fill the holes and and for the exterior installations repaint them to match your existing walls. It’s a simple, fast, clean and effective method without the mess created by removing the wall linings.

What exactly are you injecting into the walls?

CosyWall is NOT spray insulation foam, expanding foam, or spray foam insulation. It’s a DRY spray-in type insulation. This means you’re not filling the cavity of your home with moisture.  CosyWall is perfectly safe for everyone including children and pets. It has no added Formaldehyde, it’s also water repellent, durable and won’t catch fire. CosyWall is durable and will not shrink or settle in the cavity.

Is CosyWall Insulation suitable for all homes?

CosyWall Insulation is suitable for most homes build pre 1990. But to ensure it’s right for all our customers, our professional team will carry out an assessment to check suitability – importantly this assessment is Free!

Are there any compliancy or regulations I need to know about?

CosyWall Insulation takes care of all the compliance for you – so you can sit back and let us do all the hard work.

Getting Adequate Wall Insulation

We all know that the majority of New Zealand’s ageing housing does not have adequate wall insulation, and while an effort is being made to retrofit ceilings and floors, the absence of wall insulation dramatically reduces the benefit of this effort.

The key to good thermal performance is a completed thermal envelope – and without adequate wall insulation this is not attainable.

A variety of wall insulation systems have been retrofitted to New Zealand homes. Traditionally these were installed by small-scale operators with limited technical capabilities using products such as blown cellulose or sheep’s wool. The absence of regulated installation systems and quality moisture repellent materials put off most consumers which resulted in very few homes being retrofitted using these technics.

Expanding wet foam systems, installed via small holes in the linings, gained popularity during the 2000’s, but clarification on the requirement for building consents; coupled with bad publicity (mainly focused on the shrinkage of the foam), reduced the popularity of this system.

The good news is there are new alternatives to removing the linings or cladding when retrofitting wall insulation. Blown insulation systems are again making retrofitted wall insulation viable, and there are a number of solutions available.

If you are considering retrofitting wall insulation it is important to choose a company that uses an audited system. This should include assessment of the building to ensure it is suitable and the product shouldn’t introduce moisture to the cavity during installation. It should feature some form of water repellency, a proven cladding reinstatement method and documentation showing compliance with the NZBC.

The installation of all wall insulation requires a building consent, but exemption may apply to systems in some areas. A reputable company can help you through this process and ensure you get a great result from the new retrofitted wall insulation.

Rental Home Insulation

New Zealand Landlords only have a year to comply with new insulation requirements for rented properties or face a fine of up to $4000.

The requirement to insulate ceiling and underfloor spaces of a rental home by 1 July 2019 is compulsory under the Residential Tenancies Act.

Many landlords wrongly think they can hold off complying with the Residential Tenancies Act (RTA) insulation regulations and wait for more regulations under the Healthy Homes Guarantee Act.

That is wrong. Landlords must still provide rental home insulation in the ceilings and underfloor by 1 July 2019 under the RTA.

Some landlords might have done the insulation themselves, but DIY may not cut it. The insulation must meet a certain standard, be installed correctly and meet fire safety and other regulations.

Professional insulation compaines offer a wide range of products and prices, but investors and homeowners need to look at the R-value (thermal resistance) of the product being used to ensure the quotes are comparable.

Landlords and homeowners who want to get insulation installed over the next 12 months could find themselves paying higher prices and face lengthy installation delays . Don’t hesitate, get your insulation today.

How landlords can sort rental home insulation

  • Insulation statements are compulsory with all new tenancy agreements.
  • Insulation for ceiling and floors will be compulsory for all rental homes from 1 July 2019.
  • Installations must comply with regulations and be safely installed.
  • A landlord who fails to comply with the regulations is breaking the law and may be liable for a penalty of up to $4000.
  • Tenants who have a problem with insulation must first talk with their landlord.
  • The Tenancy Tribunal can order landlords to comply with insulation regulations.
