Weathershield™ Insulation – 25lb

WEATHERSHIELD™ cellulose insulation is manufactured from a minimum of 85% locally-sourced post-consumer recycled newsprint. Non-toxic additives are applied to the uniquely fiberized paper generating a building material with superior thermal and acoustic properties, as well as exceptional resistance to fire, moisture, mould and pests.

WEATHERSHIELD™ insulation is an excellent choice for use for horizontal or moderately sloped attic spaces up to 4 ½:12 inch pitch, successfully filling the irregular cavities and preventing air infiltration and convection. This product can also be applied pneumatically to walls, ceilings and floors in thermal and soundproofing projects. WEATHERSHIELD™, part of the “Greenest of the Green” family of insulation products, is an environmentally safe and sustainable way to reduce energy consumption in residential and commercial building projects and to efficiently maintain comfortable climate in four season environments.

This product manufactured proudly in Central Canada and available for regional, national and international shipping. WEATHERSHIELD™ insulation is an excellent product choice for distributors and dealers. Please contact us for more information to become an authorized distributor/dealer.
