Thermafiber is a leading manufacturer of Mineral Wool insulation products. For decades we have been a pioneer in perimeter fire containment systems. Our commercial insulation products are installed in 6 of the 12 tallest buildings in the world, and is the #1 specified commercial mineral wool.
Thermafiber is now bringing international expertise to Canada by offering a complete range of residential and commercial insulation products that conserve energy, control sound and provide exceptional fire protection.
Thermafiber® RainBarrier® continuous insulation products are designed for exceptional performance in rainscreen and exterior cavity wall construction applications. With a full portfolio of continuous insulation products and a wide range of compressive strengths, Thermafiber® RainBarrier® mineral wool insulation has a solution available for many façade types while being compatible with various mechanical attachment methods and air barrier systems. All RainBarrier® products are non-combustible, fire-resistant, vapor permeable, and are easy to fabricate & install.
Continuous insulation is insulation that is continuous across all structural members without thermal bridges other than fasteners and service openings. It is installed on the interior, exterior, or is integral to any opaque surface of the building. Benefits of continuous insulation include:
Reduces thermal bridging and increases overall R-value. Thermal bridging is a type of heat loss which occurs when heat flows through the building envelope via a continuous path, such as through wood or, more commonly, highly conductive steel framing members. Thermal bridging affects whole wall R-value
Simplifies installation of continuous air and water barriers. By creating continuous insulation, the air and water barrier can also be installed in the exterior wall cavity with minimal interruption.
Reduces moisture concerns. Continuous insulation reduces the possibility of condensation within the wall when warm, moist air is prevented from reaching a dew point temperature.
The Owens Corning® Thermafiber® RainBarrier® ci High Compressive insulation portfolio is designed to be used in continuous insulation applications where the cladding and cladding attachments are fastened outboard of the mineral wool insulation. In this application, only fasteners penetrate through the insulation, eliminating almost all thermal bridging and meeting the ASHRAE 90.1 definition of continuous insulation. Owens Corning® Thermafiber® RainBarrier® ci High Compressive insulation uses ThermaCrimp™ technology to make the highest compressive strength mineral wool ci on the market. This proven technology can be used behind any cladding type – including combustible and open-joint assemblies. Technical Bulletin
RainBarrier® ci High Compressive Max is designed for use behind heavy weight cladding types – including combustible and open-joint assemblies. RainBarrier® ci HC Max Data Sheet
Owens Corning® Thermafiber® RainBarrier® 45 and HD mineral wool insulation are designed to fit between cladding attachments elements, such as masonry ties, girts, and clip & rail systems. The pliability and flexibility of these products enable these products to form around most attachment elements without the need for cutting or notching.
Thermafiber® RainBarrier® continuous insulation provides thermal insulation, fire resistive characteristics, and acoustical control while efficiently draining water from a wall cavity system. All Thermafiber® RainBarrier® products are non-combustible and compatible with common wall ties, adhesives, and air barrier systems.
Owens Corning® Thermafiber® RainBarrier® 45 mineral wool insulation product is a preferred product for most semi-rigid applications. RainBarrier® 45 Data Sheet
Owens Corning® Thermafiber® RainBarrier® HD mineral wool insulation is a high density board providing additional thermal performance when ASTM C612 Type IVB is required in the specification. RainBarrier® HD Data Sheet
Thermafiber® SAFB™ is sound absorptive mineral wool batts designed to provide acoustic and fire protection in various wood and steel framed load bearing and non-load bearing sound and fire rated interior construction assemblies. SAFB™ batts are non-combustible, non-corrosive, non-deteriorating, and mold resistant.
