Insulation Renovation

Insulation Renovations Auckland

Renovating is the perfect time to add insulation — especially into walls, since they can only be insulated with batts while the framing is exposed. We work closely with homeowners and builders to install insulation at the right stage of the build or renovation — whether it’s adding wall batts before plasterboard, or fitting new ceiling/underfloor insulation as a standalone upgrade.

We regularly help with:

Villa & bungalow renovations (adding comfort and energy efficiency to older homes).
Extensions & alterations (ensuring new spaces are warm and healthy).
Full-gut renovations (bringing homes up to modern standards).

💡 Important: We don’t offer injected/blown insulation for finished walls. Our service is designed for projects where framing is exposed.

Kaiser Insulation has been amazing to deal with. Alex is a absolutely champion, really friendly and easy to deal with and did a amazing job at insulating both our ceiling and external and internal walls. Competitive pricing and great result so would highly recommend! Thanks again!

Rashik Kanji

Alex is super friendly and gets the job done. The communication was easy and the installation was smooth. They tidied up when they finished the job and even wiped the door frame and wall with wet tissues just in case there were dust escaped from their protective wear. Highly recommended!

Kera Wang

Excellent service! Great communication and a friendly, hard working team doing all the right things. This was a painless and easy process for us, retrofitting our ceiling insulation. Alex was kind enough to give us two quotes, one more reasonmable than the other and explained the difference between the two. We chose the thicker option. And we are stoked with the results! Thanks so much guys and keep up the great work.

FAQ's

What materials do you work with?

Pretty much everything, from cost-effective to premium options. Eliment, Earthwool and PinkBatts are glasswool options while we use GreenStuf and Mammoth polyester products.

Polyester vs. glasswool?

In a new build/renovation context glasswool products are mainly specified as there is there is a huge number of options across different types and R-values (how well insulation performs). Polyester is becoming increasingly prevalent but is often cost prohibitive. We often encounter clients that have energy efficiency, acoustic, air quality, etc. concerns. Please get in touch for advice.

I have acoustic concerns?

Insulation has good acoustic properties. For the best results, insulation should be installed as part of a system, e.g. noise reduction system or similar. Speak to your builder.
