Thermal Break Concrete Foundatoin Wall

Foundation wall and drainage scott describes the basement wall assembly.

Thermal break concrete foundatoin wall. The above images show the placement of the first 140mm bottom plate and hold down straps. The separation is there in order to allow us to attach 5 of roxul comfortboard 80 to the basement foundation we ll be doing the same for the whole exterior perimeter of the basement foundation. Must extend to the foundation wall. Concrete stem wall liquid water proof barrier black 8 eps and a layer of high density drain board tied into a drain at the toe of the footing.

This photo below shows the notched eps thermal break in detail before the surrounding concrete stem wall had been poured. Looking over the plans our concrete sub is worried about the 7 thermal break between the basement and garage foundations no physical connection as currently drawn on the plans. This reduces the exterior wall s effective r value. High points are ground down to ensure a completely level perimeter ready to receive the bottom plate.

External to internal structural connections large area rain screen cladding and façade systems can impose thermal load on a main structure. The thermal break is still visible below the thin layer of concrete spill and this will be cleaned up as the foundation wall is checked for any high points. Thermal break material tbm 1 a high strength thermal break material that reduces heat loss at balcony canopy shelf angle roof post and other structural steel connections where larger forces exist due to moment and dead loads. Seams must be lapped 12 inches see figures 2 1 and 4 6.

The intersection at a slab on grade to foundation wall and exterior wall to foundation transition are both areas where heat flows out of a building. Thermal break solution for foundation wall the wall to foundation transition is often overlooked as a source of heat loss within the building envelope. Detail of tss thermal break concrete slab solution showing structural load bearing anchor design. The as poured thermal break system is shown below.

The use of a farrat structural thermal break will remove internal condensation risk whilst maintaining the connections structural performance. Foundations are part of a buildings thermal envelope. Six mil black polyethylene or approved equal must be laid over the ground within all crawlspaces. Foundation wall thermal break.

The walls of the basement foundation 9 and garage foundation are scheduled to be poured next week. The tss system easily adapts to multiple concrete slab to foundation wall design configurations while providing an effective thermal break concrete slab solution. Thermal break blocks reduce heat loss at foundation to wall transitions and roof to parapet intersections.
