Customer Testimonials

Here's what our customers are saying about Insultech

The heat pump is not running full on all the time. Even on a cold day, we can turn it off during the day and then, when we turn it on again later in the evening, it just heats the house up much quicker. Amazing, wish we had done it years ago.

Debbie B

The comfort levels in my home have improved out of sight. I am thrilled with the results plus Leigh and his team were brilliant. I am 100% satisfied.

Maureen W

The house is easier to heat and not as cold on frosty mornings. Plus, we live on a busy road and now cannot hear the traffic anymore. CosyWall has made a huge difference.
