Since a double-layered wall is thicker than a single-layered wall, its ability to insulate sound and heat of seems to be better. However, in the hot and humid tropical weather conditions of Vietnam, double-layered walls with common structures, especially those West – facing wall, are unable to match the heat insulation demand because they do not have the gap for air to circulate and radiate heat. Moreover, the fact that there is no gap to dissipate sound leads to lower noise cancellation.

Remak® XPS Insulation Foam is lightweight, easy to cut and install, it is easily inserted between 2 layers of walls in construction. It has the effect of preventing heat from leaving or entering the building, maintaining thermal stability, thanks to its extremely low thermal conductivity. Besides, it also helps remove noise, bringging more comfortable living and working space.

Note: During the construction process, it is necessary to put a connecting steel belt between the two walls to ensure a solid connection.
