The MK5 Near Zero Heavy R value foundation, designed as an 8″ structural slab over an R50 base, for Residential or Commercial installations.
MK5 ” Flat-Slab Technology ” rules as a major part in the required Thermal envelope, there are no basements, there are no crawl spaces, no gases, no moisture, nothing cracks, nothing moves, there are no sounds and nothing feels like Hot or Cold.
Leaning towards Passive you can install vent pipes in the 8″ structural floor, any size, any direction. Towards MK5 Near Zero we install solar / electric / gas conversion kits for in-floor radiant heat ( 2 runs around the perimeter ) boiler boards, on demand water systems, etc
