Some fiber cement panels act as a drained

Post by akterchumma699 »

The system is a form of double-wall construction that uses an outer layer to keep out the rain and an inner one to provide insulation, prevent excessive air leakage, and carry wind loading.

The outer layer breathes like a skin while the inner layer reduces energy losses. The structural frame of the building is kept absolutely dry, as water never reaches it or the thermal insulation. Evaporation and drainage in the cavity removes water that penetrates between panel joints. Therefore, there is no significant pressure differential to drive the rain through joints. During extreme weather, a minimal amount of water may penetrate the outer cladding. This, however, will run as droplets down the back of the cladding sheets before dissipating through both evaporation and drainage.

/back ventilated rainscreen. This is a paneled wall system installed to framing whatsapp number database using clips that hold the panels away from the structure.

The clips provide different depths of air space depending on the designer’s preference, and moisture is released through this air layer. Fiber cement panels are installed over a starter track with weep holes.

Fiber cement panels are profiled along all four edges, so both horizontal and vertical joints between the installed panels are ship-lapped. A factory-applied sealant is applied to the top and right panel edges, ensuring all factory joints will contain a sealant and no additional sealant or caulk is necessary for installation, except at termination conditions.
