Compressive strength is an important durability feature
FOAMGLAS® insulation retains its shape and strength under pressure. 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 obviously an important feature for insulation, but it is not always connected to sustainability. It should be.
Depending on the product type, FOAMGLAS® is capable of bearing loads of 500kPa to 1600kPa through the lifetime of the application, maintaining its insulation properties without compression, degradation or distortion. There is no need to use additional heavy-duty protective layers in flat roof applications.
Even after FOAMGLAS® insulation has been installed, it is still possible to change the layout on the roof and place new structures on it because FOAMGLAS® cellular glass can support them. This means that there is no need to replace the insulation when converting a flat roof into an active roof with plants, solar panels or even a parking lot.
Roof plans and layouts can be changed, but FOAMGLAS® insulation stays put.
No insulation change = no new emissions
FOAMGLAS® insulation can support heavy loads and does not need to be changed when the layout and plans of a roof change, and this links directly to sustainability.
It means that there is no new raw material needed and no new emissions generated from manufacturing, recycling and transportation as the insulation stays put and does its job.
The durability of FOAMGLAS® products is practically unlimited when they are used as designated. In the EPD, the declared service life is 100 years* based on flat roof application, so FOAMGLAS® insulation offers not only compressive strength but also longevity.
“FOAMGLAS® insulation has always offered peace of mind for those who think for the long run and want to mitigate risks of leakages and loads. The same longevity that results in low maintenance costs and peace of mind regarding performance also offers the essence of what a sustainable solution is – a solution that stands the test of time and won’t need to be replaced over and over again,” says Els Bleus, Head of Products & Systems at Foamglas Building EU.
