How is it installed?

Fibreglass insulation

As you may know by know fibreglass comes in two forms; blankets and loose fill. Why? This is as depending where the insulation is going (between timbers, underfloor, loft floor) the installers will choose the most suitable one.

Loose fill is applied to the floor of a loft, so this would be installed using a hose. Picture a fire fighter carrying a hose and that is exactly what it would look like. Installers will spray enter your home with a huge hose and spray the confetti-like fibreglass across the loft floor.

Fibreglass blanket is installed different. The candy floss-like insulation is rolled out and cut to size of your timbers and stuffed in.

Spray Foam Insulation

As the name suggest spray foam insulation is installed by a unique technique called spraying. Similar to fibreglass loose fill, spray foam requires a hose that will be bought into the loft. The foam is sprayed onto the wall and expands. Requires no surgical-percise cutting so it will not miss any gaps and crannies.
