We offer new build cavity wall insulation to residential and commercial builders. The benefits of blown cavity wall insulation over board products are numerous. Board products are more expensive, and will incur additional install costs. If you look at the difference on install costs you will see that fitted board insulation can cost around 1 pound per m2 more to install, as it adds 2-3 man days to the build. Fitted board insulation requires special corner joints and riser pieces which add fitting complexity and additional cost to the build. On top of this a vertical DPC (Damp Proof Course) will be required from top to bottom on all corners. Other issues to consider with the board product are its storage on site, board wastage, and it getting damaged, wet or stolen which are often not been taken into consideration. Full fill blown cavity wall insulation will guarantee a 100% full filled cavity with no gaps.
