Maximum of thermal insulation

The W’all-in-One® PG90 offers maximum thermal insulation (0.24 U) at a minimal thickness (90mm). In other words, increased comfort, reduced energy costs and a minimal loss of space. The thicker the W’all-in-One®, the higher the insulation value (see also: W’all-in-One® PG60 and W’all-in-One® PG70). The W’all-in-One® PG90 consists of a highly insulating, dimensionally stable, fire-resistant PIR foam panel between two plasterboard panels. The W’all-in-One® PG90 is fixed against the back wall (with or without cavity). If it is not possible or permissible to do so, you can opt for the W’all-in-One® free-standing. .

DThe W’all-in-One® PG90 complies with the Building Decree and is KOMO certified. The wall is not susceptible to damp and offers a constant high thermal yield. This facing wall is the perfect solution for cold and/or damp walls.
