Owens Corning® is expanding its Thermafiber® RainBarrier® continuous insulation portfolio with the introduction of Thermafiber RainBarrier Dark™. Equipped with a fiberglass dark veil facing material that is adhesively applied and manufactured to maintain its integrity post-installation, Thermafiber RainBarrier Dark™ is designed to help architects achieve both aesthetic and performance objectives.
Innovative open joint assemblies and imaginative claddings are spotlighting the façades of today’s structures. At the same time, today’s energy codes have made continuous insulation a de facto component in rainscreen and cavity wall construction applications. Beyond defending against thermal bridging and supporting the energy efficiency of the envelope, non-combustible mineral wool continuous insulation is engineered to repel and drain water and manage vapor moisture. It even brings acoustical benefits to help manage noise in the outer assembly.
The introduction of Thermafiber RainBarrier Dark helps preserve the integrity of the building’s design. Designers don’t have to choose between a high-performing façade and a continuous, non-disrupted aesthetic. In installations where continuous insulation may be visible, Thermafiber RainBarrier Dark blends into the background, supporting performance without interrupting the design ethos. Inspired by customer feedback, Thermafiber RainBarrier Dark is designed with flexibility in mind for easy installation. The facing is designed to avoid the cracking that can occur with more rigid materials.
The dark veil facing on Thermafiber RainBarrier Dark is adhesively applied, allowing it to stay intact during and following installation. In some designs, the subtle contrast achieved by the dark facing may even contribute to the aesthetic intrigue of the building design. Regardless of whether it blends in the background or adds a subtle aspect to the façade, the performance of RainBarrier Dark 45 and RainBarrier Dark HD remains the same. Also, like all other products in the RainBarrier portfolio, both Dark offerings contain a minimum 70% recycled content and contribute to credits in several green building programs, such as LEED® and Green Globes®.
