Lewis Deck in an ICF Build.

The building was constructed using ICF blocks that are to have a rendered finish. Internally the ground floor is a concrete slab and the upper floor has timber posi-joists with the Lewis Deck and resilient strips laid above. 16mm underfloor heating pipes are then clipped into our new clip rail system with a free flowing screed then poured on top, 50mm thick. This then gives 20mm cover to the heating pipes, maximising the efficiency of the whole system.
