Silvapor
What is Silvapor
Silvapor is a hydrophobic insulating aggregate made from coated expanded perlite. This water-repellent, non-flammable, loose-pour insulant significantly improves the thermal performance of masonry walls and floors and is particularly suitable for use in external cavity walls. It is produced and tested to BS EN 14216-1:2004 Thermal Insulating Products for Building - In-situ Thermal Insulation formed from Expanded Perlite (EP) Products Part 1 : Specification for Bonded and Loose-fill products before installation.
Benefits
Silvapor minimises heat loss in winter and heat gain in summer. It also protects agains water transmission and wind-driven moisture penetration and so assures constant insulating efficiency.
