The timbers dry without great dramas. What happens if the roofing system leaks, yet the water is held within or behind a layer of foam? Well the water remains close to the lumber, it doesn't damp the ceiling, so the early tell story indication is eliminated as well as the timbers do not dry out.

The Facts About Spray Foam Loft Insulation Revealed

The water that obtains in can (depending on the sort of foam) action about within the framework of the foam, with the timber behind the foam or in gaps behind it.

Well it will have a result, however doesn't this after that entirely negate the worth of the insulation developed to stop warm air obtaining out and cool air getting in?

As the roof covering warms in also the weakest winter sun, the troubles lessen as well as the roofing dries fairly swiftly.
