You have probably heard that homeowners with spray foam insulation installed in their lofts are having problems getting equity release or buyers struggle to get a mortgage.
Homeowners are being told their loft space has been compromised by the spray foam and it doesn't matter if it's open or closed cell, there is no difference as far as lenders are concerned.
Air sealing your loft space is not a good thing, in fact, to the contrary it is an incredibly bad thing to do.
Filling the loft with any type of foam and sealing the loft, you are blocking any and all natural ventilation.
All homes have eaves, this is the area where the floor of the loft meets the bottom of the roof. The eaves provide natural air flow into the loft and when spray foam is installed and blocks the eaves, this stops the air flow.
Some homeowners have installed vented soffits, ridge tile vents, or tile vents on the sloping faces of the roof, all of which are designed to allow cold air into the loft area. By doing this and maintaining air flow your loft will be cold and remain free from moisture, your timbers will be able to breathe and they should be free from damp or timber decay.
Most registered surveyors will recommend the removal of spray foam as it is generally not needed and completely unnecessary.
