Insulation

Whatever their size or thickness, rigid EPS panels can be used as insulation for walls, roofs and heavy building foundations for any kind of structure or exterior finish.

EPS is a light, rigid material which is easy to handle. Because it provides long-lasting energy efficiency which doesn’t diminish over time, it is considered to be permanent insulation.

Of all the types of rigid insulation on the market, EPS stands out through its excellent cost/R-value ratio.

Perfect for residential, commercial and cold storage usages, EPS panels and EPS blocks are available in a range of thicknesses and a wide variety of densities.
