Renovating a home, a good time to add wall insulation

Repainting or renovating? The perfect time to add wall insulation

Written by emdagency on . Posted in Home Owners.

If you’re planning on repainting or renovating your home, there’s one more upgrade worth considering, adding wall insulation. It’s easier to do than you might think, especially with CosyWall Insulation. Whether you’re giving the place a fresh coat of paint or pulling off wall linings during renovations, now could be the best time to improve your home’s comfort and energy performance. 

Insulating during repainting 

If your wall linings are staying in place, we can install CosyWall from the outside or inside. Our team drills small access holes into the wall cavity, then blow in the insulation, and seal the holes up once each section is filled. It’s tidy, efficient, and a great option when you’re already planning to repaint either inside or out. You get all the benefits of a fully insulated home without having to remove wall linings. 

Weatherboard walls 

We’ve worked on thousands of New Zealand homes with weatherboard cladding. For this type of wall, we usually access the cavity by drilling small holes through the exterior weatherboards. Once the insulation is blown in and evenly packed, we seal the holes, fill them, and sand them smooth. The area is ready for painting straight away. 

The process is quick and tidy. You won’t even know we’ve been there, apart from the warmer, more comfortable living environment. 

Internal walls 

We can also insulate internal walls. This can help with noise control, temperature consistency, and energy savings throughout the house. As with external walls, we drill small access holes, fill the cavity, then patch and sand the walls so they’re ready to repaint. 

Adding insulation to your internal walls during repainting or renovating means you don’t need to come back to it later. It’s a simple upgrade that adds real value to your home. 

Insulating during renovations 

If you’re removing wall linings as part of your renovation, we offer the CosyWall Off Linings solution. This method is ideal when you’re opening internal walls and want to make sure your insulation is done right. 

Introducing the CosyWall Off Linings solution 

The Off Linings solution is designed for homes undergoing renovations. Instead of installing segment insulation, which can leave gaps or compress over time, we use blown insulation to fill every part of the wall cavity. It wraps around wiring and pipes and creates a complete thermal seal. 

This method lines up with the standards of NZS 4246:2016 and supports long-term energy performance. It also helps reduce moisture issues and improves the overall comfort of your home. Builders and homeowners alike find it a reliable option that works well during renovations. 

You can refer to the BRANZ External Wall Insulation Techniques research for more detail on this approach.
