Compressive strength is an important durability feature
FOAMGLAS® insulation retains its shape and strength under design loads. This means that there is no need to replace the insulation when converting a flat roof into an active roof, for example.
Compressive strength is a key durability feature for insulation. By supporting long service life* and reducing the need for replacement, durable insulation can contribute to improved environmental performance over the building lifecycle.
Depending on the product type, FOAMGLAS® insulation can bear loads of 500 kPa to 1600 kPa and maintains its thermal performance under sustained load, supporting long service life in demanding applications.
In certain roof applications, the high compressive strength and dimensional stability of FOAMGLAS® cellular glass insulation can allow changes to the roof layout or the addition of new structures, depending on the system design.
Roof plans and layouts may change over time, while the insulation layer can remain in place, depending on the roof system design.

No insulation change = no new emissions
FOAMGLAS® insulation can support high loads and, in suitable roof systems, may remain in place even when roof layouts or uses change. This durability can reduce the likelihood of insulation replacement over the service life of the building.
By reducing the need for replacement, durable insulation can help avoid additional material use and the associated environmental impacts from manufacturing, transport, and end‑of‑life processes over time.
The durability of FOAMGLAS® cellular glass insulation is reflected in its declared reference service life. A declared reference service life of 100 years is stated for flat roof applications in the Environmental Product Declaration (EPD), based on long‑term FIW studies of installed flat roofs.*
“FOAMGLAS® insulation has always offered peace of mind for those who think for the long run and want to mitigate risks related to loads and long‑term performance. Longevity and low maintenance requirements are key aspects of solutions designed to perform over decades,” says Els Bleus, Head of Products & Systems at Foamglas Building EU.
