Spray-applied polyurethane foam is a chemically-modified polyurethane foam applied to the underside of the roof which bonds slates and tiles to each other and to structural or supporting timbers to replace the anchorage of fixing nails. Spray-applied polyurethane foam expertly applied between floors in domestic properties has sound deadening and thermal qualities. In domestic properties a warmer, drier, cleaner roof space provided by spray-applied polyurethane foam to the underside of the roof eliminates the risk of pipes and tanks freezing.
