Thermal Break Concrete Foundatoin Wall

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 concrete foundatoin wall.

Must extend to the foundation wall. Seams must be lapped 12 inches see figures 2 1 and 4 6. Detail of tss thermal break concrete slab solution showing structural load bearing anchor design. Thermal break solution for foundation wall the wall to foundation transition is often overlooked as a source of heat loss within the building envelope.

Used to create a thermal break see figure 2 3 for possible detail 502 1 6 7 ground cover. 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. High points are ground down to ensure a completely level perimeter ready to receive the bottom plate. Thermal bridging at foundation wall transitions creates heat loss at the foundation perimeter.

The as poured thermal break system is shown below. 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. 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 blocks reduce heat loss at foundation to wall transitions and roof to parapet intersections.

This photo below shows the notched eps thermal break in detail before the surrounding concrete stem wall had been poured. The walls of the basement foundation 9 and garage foundation are scheduled to be poured next week. The use of a farrat structural thermal break will remove internal condensation risk whilst maintaining the connections structural performance. External to internal structural connections large area rain screen cladding and façade systems can impose thermal load on a main structure.

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. Thermal modeling has shown that the r value of the exterior wall can be reduced by as much as 70 due to thermal bridging where the wall foundation and interior floor slab meet. Six mil black polyethylene or approved equal must be laid over the ground within all crawlspaces. Foundation wall and drainage scott describes the basement wall assembly.

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. Foundations are part of a buildings thermal envelope. Foundation wall thermal break.
