PIR insulation

PIR insulation boards are widely applicable and perfectly suitable for insulating a flat roof or cavity wall. PIR has excellent thermal quality and insulates better than many other insulation products, even at low thickness. This type of insulation also comes in many forms, including spray-foam, liquid or rigid insulation boards and panels. Due to this, it is very flexible and versatile and can be used on a number of different surfaces.

EPS Insulation

EPS (Expanded Polystyrene) Insulation is a lightweight insulator, made of polystyrene foam beads. EPS is a versatile insulation material that is widely used in all kinds of construction and insulation projects due to its good insulating quality and affordability. EPS insulation boards are light, easy to handle and safe to use.

Glass Wool insulation

Glass Wool insulation is affordable and one of the most commonly used insulation materials. This type of insulation is made from recycled glass and sand and is generally produced in blankets. Fiberglass insulation has an open structure with very high insulation value, making it easy to use as wall insulation. Fiberglass insulation is a naturally sound-absorbent material that greatly reduces sound transmission.

Rock Wool Insulation

Rock wool is a non-combustible and sound-resistant insulation material that consists of basalt, a volcanic rock that is 100% recyclable. The superior performance of mineral wool makes it the ideal choice for many types of external wall constructions, including masonry cavities, timber frames, metal frames, rainscreen and external facades. This type of insulation has a long lifespan of an average of 75 years, during which the insulating properties are not compromised.
