What’s the difference between raised and standard loft boarding?
Standard loft boarding are floorboards fixed directly to the floor joists which squashes insulation or requires the removal of layers. Squashing your insulation stops it from working! That’s a fact. It reduces its efficiency by up to 50% and this ultimately ends up costing you money because it increases your heat loss and therefore raises your energy bills.
Although some installers and joiners recommend standard boarding, mainly because is it cheaper and easier to install than raised flooring, it can have adverse effects on your property.
In our years as approved loft Insulation installers we have had a lot of experience with lofts that have been boarded directly onto the joists and the problems that have arisen as a result especially if the insulation has been squashed into place.
