Fibreglass

Johns Manville Formaldehyde-free? fibreglass insulation provides thermal and accoustical control for both vertical and horizontal applications. Unfaced fibreglass insulation is available in a wide range of thermal resistance R-values.

Foam Board / Sheathing

Johns Manville Polyiso foam sheathing insulation boards provide a continuous layer of insulation to reduce thermal bridging and improve energy efficiency. Polyiso consists of a uniform closed-cell polyisocyanurate foam core and provides one of the highest R-values per inch of any rigid insulation.

Mineral Wool

Johns Manville Mineral Wool batts are made of inorganic fibres derived from basalt, a volcanic rock and are enhanced with glass fibres. Our advanced manufacturing technology ensures consistent product quality, with high-fibre density and low shot content for excellent performance.

Spray Foam

John Manville's complete line of spray polyurethane foam (SPF) insulation solutions provides superior thermal energy efficiency, as well as advanced air and sound control. SPF insulation completely covers gaps and voids, works in hard-to-insulate areas and can exceed the performance of traditional fibreglass insulation. Both Johns Manville SPF product categories, open-cell and closed cell, deliver high yield, superior performance and exceptional sprayability.

Tile Backer Board

Johns Manville GoBoard? LT is the latest ultra-light, waterproof and durable tile backer board. It’s engineered for durability, yet is up to 85% lighter than cement boards. GoBoard LT is easier to handle and can be cut right where it’s installed with a basic utility knife without crumbling or disintegrating. And, best of all, it has waterproofing already built‐in, reducing installation time and eliminating extra steps since only board joints and fastener locations need to be sealed.
