When designing a well-insulated home, the walls and roof space are often given much consideration while the foundation is somewhat ignored; or more crucially, incorrectly and ineffectively laid. A Passive Slab is an insulated foundation system, tailor designed and engineered to your plans to achieve the best possible insulating capabilities at all locations. Most importantly, key areas of cold bridging are avoided at critical wall to floor cold bridges.

A Passive Slab is faster and surprisingly cheaper than a traditional strip foundation. Most importantly, this system completely eliminates cold bridging, resulting in an impressive Passive floor u-value of 0.10 w/m2k.

An somewhat overlooked benefit is that this is a complete insulated system with no need to pour additional screed. The time and effort cutting and laying insulation boards is eliminated. All services such as underfloor heating are run within the slab at install, and as it is the finished floor, drying time before flooring is also eliminated!

A Passive Slab system is quicker, easier and no more expensive than a traditional strip foundation; in fact, it’s usually cheaper! Most importantly, alongside these benefits, this system completely eliminates cold bridging, resulting in an impressive Passive floor u-value of 0.10 w/m2k.

A thermal or cold bridge occurs where there is a break in the continuity of the insulation within a building. This efficiency losing flaw can be most commonly found at critical wall to floor junctions.

To combat this, our system is tailor engineered to your plans to super insulate the wall to floor junction with precision detailing, enhancing thermal efficiency and eliminating crucial cold bridges.
