SilveRboard® Graphite XS by Amvic: A higher performing insulated exterior wall sheathing

As codes and standards change, it is important to constantly find innovative ways to maintain and improve the quality of a building. For Amvic, that means providing builders with the right products to achieve that quality. That is why SilveRboard Graphite was developed.

SilveRboard® Graphite XS is an expanded polystyrene (EPS) base material that is embedded with carbon graphite particles, which increase the thermal performance of the EPS insulation. The Graphite EPS beads reflect radiant heat energy similar to the effect of a mirror that reduces thermal conductivity and increases the material’s ability to resist the flow of heat or R value.

SilveRboard® Graphite XS is a combination of graphite-embedded EPS beads, laminated on both sides with perforated reflective film. SilveRboard® Graphite XS holds its R value for the life of the product and is an ideal insulation for exterior walls in the Canadian environment.

SilveRboard® Graphite XS is effectively durable to resist construction site and weather damage. It is also light weight, easy to handle, and highly flexible for radius walls. This type of insulation is perfect for builders looking for a sheet with reduced thickness that provides more flexible options and a leveled rigid surface for exterior finish materials. It also accepts taping, which adheres quickly and permanently to the SilveRboard film.

SilveRboard® Graphite XS creates a higher-performing thermal envelope, maximizes heating and cooling efficiency, and improves indoor air quality. It is designed with built in air and moisture barriers and delivers a higher, long term, stable R value.
