cavity wall insulation - why sheet & board insulation isn't always a good idea

Badly fitted board & sheet insulation in this cavity is little better than having nothing in your cavity

While out on a site visit recently I saw this cavity wall with board insulation in situ. Having my Iphone with me I snapped this and it illustrates a point we make a lot to our customers. Now here at Fusion we loathe negative marketing i.e. slagging off the competitions product or agents to sell your own. Equally when an observation is valid and when a product brand isn't named then we feel it's fair comment  to point out some of the inadequacies in generic systems , in this case board or sheet insulation. Board or sheet insulation in theory are great performers , but out on site unless your quality control is very vigilant you'll end up with what we see above i.e. badly fitting boards with 'open' joints. The end result is greatly reduced thermal performance. You think you have insulation protecting you but if there are too many gaps in the insulation then frankly you will suffer. Sprayfoam offers an alternative in that when we inject a cavity with liquid foam it expands and fills the cavity with solid foam. What's more our latest German foam is water repellent giving you additional peace of mind.  Have a look at our videos on sprayfoam and you'll soon understand the potential of this exciting system
