The Glavel Foundation System is a complete border insulation formwork that insulates the foundation of a building from the ground up. With exterior facing boards, moisture and vapor are prevented from entering a foundation. Glavel foam glass gravel is used below slab to complete the system.
These glass-derived products are rot and pest resistant, hold high compressive strength, and thermal insulation of R1.7 per inch (aggregate) and 2.7 per inch (boards). When competing against traditional installation methods, the RDS system wins out in resiliency, cost, and environmental friendliness.
Water resistant – Closed cell structure
Vapor tight – Prevents moisture entry
Non-compressible – 152 psi compressive strength
Thermal insulation – R2.7 per inch
Produced from recycled glass – Categorized as ‘clean fill’
Non combustible – Will not burn, nor propagate fires
Inert – Prevents rodents, termites, bacteria, and rot
Foam Glass Gravel
Lightweight – 9.8 pounds per cubic foot
Load bearing – 116 psi compressive strength
Thermal insulation – R1.7 per compacted inch
Self interlocking – Distributes loads evenly
Closed cell – Acts as a drainage layer
Frost heave resistant – Will prevent freeze and thaw cycles
Water resistant – Closed cell structure facilitates runoff
Board Tech Specs
With the Glavel foundation insulation system, a healthy, high performance building can be built from the foundation up. The combination of this system can help to create a low-embodied carbon site free from rigid foam board insulation.
