Cavity Fill

Silvapor coated expanded perlite is a hydrophobic insulating aggregate. This water repellent, non-flammable, loose-pour insulant significantly improves the thermal performance on masonry walls and floors and is easily installed without special training or equipment for new build, extensions and established properties.

Permanency	Silvapor pre-coated expanded perlite is inorganic and therefore, rot, vermin and termite resistant, non-combustible with a fusion point of approximately 1280^oC and is as permanent as the walls and floors that contain it. The loose granules support their own weight within the cavity without settling as verified by actual field measurements. The free flowing nature of the product seeks out and completely fills the smallest crevices within the cavity without bridging.
Benefit	The total functional performance of Silvapor is to minimise winter heat loss and summer heat gain, thereby providing greater comfort at a lower cost. The product protects against water transmission and wind driven moisture penetration and thus assures constant insulating efficiency.
