EPS for Roofing?

ISOMO EPS roof insulation – stable, 100% circular, and future-proof
Anyone insulating a roof today expects more than just a good λ- value. Roof insulation needs to be stable, durable, and reliable in the long term. With ISOMO’s EPS roofing solutions, you choose insulation that does not shrink or degrade and maintains its performance – year after year.

Dimensional stability without compromise
Anyone installing a roof needs it to remain perfectly sealed even after ten years. Unlike PIR and PUR—which can shrink significantly due to moisture and temperature fluctuations (by as much as 3.00% or more, according to the manufacturers themselves)—ISOMO’s EPS remains virtually unchanged in shape.

Moisture-safe and reliable in any roof assembly
EPS withstands water vapour, condensation, and temperature fluctuations like no other material. It is unaffected by moisture, has extremely low water absorption, and can safely release vapour gradually through the interstitial spaces between the beads. A robust vapour barrier using EPS creates a vapour-retarding envelope within your roof assembly!

Lightweight, fast, and safe to install
ISOMO EPS roof insulation is lightweight and resilient, making on-site handling significantly easier. The boards are less prone to breakage, easy to cut, and do not generate irritating dust. This speeds up installation and improves comfort for installers. Compared to rigid, heavy insulation boards such as PIR, PUR, or mineral wool, EPS is more practical, robust, and forgiving during installation.

Ready for new regulations
ISOMO already incorporates an average of approximately 20% recycled material into its product range, making it ready for stricter European and Belgian regulations that mandate the use of recycled content. By choosing ISOMO’s EPS roof insulation, architects, contractors, and developers are investing in a sustainable system that will soon become mandatory.
