Do you need to install a vapor barrier when using SilveRboard under a concrete slab?

By taping the joints of SilveRboard you eliminate the need for a dedicated vapor barrier. Refer your local building code.

Does SilveRboard have a high enough density to be used under a concrete slab?

Yes, we offer SilveRboard in three high density options – 35psi, 44psi and 60psi to meet with construction requirements.

How do you utilise Silverboard in an exterior foundation/ frost wall application?

High density SilveRboard is ideal for foundation and frost wall insulation applications. Due to its unique double face vapor barrier surface film and exceptional flexural strength, it can be used both internally and externally ( between foundation walls and soil backfill.) The board can be glued, screwed or nailed to concrete walls.

What type of tape can be used with SilveRboard Graphite?

An approved construction sheathing tape can be used with SilveRboard Graphite.

Can SilveRboard Graphite be used on radius wall applications?

Does SilveRboard Graphite have a CCMC report?

Yes SilveRboard Graphite does have a CCMC report, report number 14044-R.

How do you mechanically fasten SilveRboard Graphite to the frame?

SilveRboard Graphite can be mechanically fastened using cap nails or staples of appropriate length (1¾ inch longer than the thickness of the board itself).

Can SilveRboard Graphite be applied without OSB sheathing?

Yes SilveRboard Graphite can be applied without OSB sheathing as long as the required structural bracing (corner bracing and metal wind bracing) is installed. It must conform with architectural drawings.

Is SilveRboard Graphite available in breathable and non-breathable formats?
