XPS

The high resistance to compression and the excellent damp-resistance properties of STYRISoL® makes it ideal as insulation under different flooring types.

Installation under the concrete

STYRISOL® insulation boards are placed directly on the flat and stabilised foundation. A PE-foil needs to be put above the insulation to prevent the mortar from getting between the joints of the boards (which creates cold bridges).

Installation above the concrete

STYRISOL® insulation boards are placed on a smooth concrete surface. We suggest that a water vapour barrier is placed between the boards and the concrete to avoid cold bridges.

Underfloor heating

STYRISOL® insulation boards can be used in all standard underfloor heating systems.

Inner wall insulation / insulation of cold bridging

STYRISOL® insulation boards are the perfect support for stucco work or mortar layers. The surface of the boards are grooved or waffled, this ensures a good bonding.

Outer wall insulation

STYRISOL® insulation boards can also be installed as outer wall insulation. (We recommend using a professional to apply the insulation boards and for the outer stucco work).

Cavity wall insulation

STYRISOL® insulation boards are placed with the tongue upwards, close to one another and on the inner cavity wall. A ventilated cavity of at least 4 cm is needed. The wall ties have to be installed so that water cannot penetrate into the inner wall. At ground level, a damming layer needs to be applied. Water is drained off through the open grooves.
