High Compressive Strength Dimensionally Stable Foam Glass Insulation Board
This high compressive strength foam glass insulation board is a rigid insulation material supplied in grades selected for different load requirements, so designers can match the board to the actual mechanical duty of the project. The cellular glass structure resists compression, so the board can carry foot traffic in roofing, support secondary membranes on tanks, and act as a load-bearing layer under floors and parking decks without crushing or compressing over time.
Because it is also dimensionally stable, the board keeps its thickness and shape under repeated load and thermal cycling. This combination of rigidity, compressive strength and dimensional stability makes it ideal where insulation has to do structural work as well as thermal work, including foundations, plaza decks, tank bases and industrial floors.

Supply and Installation
The high compressive strength dimensionally stable foam glass insulation board is supplied as rigid boards in standard sizes and can be cut, sawn and bonded on site with conventional tools. Every batch is produced from recycled glass under a controlled kiln process and inspected against the relevant standards before dispatch. If you would like the full technical data sheet, the applicable test report or a project specific quotation, our team will gladly assist and advise on the most suitable grade and thickness for your insulation system.
Frequently Asked Questions
Q: Can this board carry load?
A: Yes. It is a rigid cellular glass grade supplied for different load requirements, and is commonly used as a load-bearing layer under roofs, floors and tank bases.
Q: Will it compress over time?
A: No. The closed-cell structure is dimensionally stable and resists creep, so thickness and performance are maintained under sustained load.
Q: Which grade should I choose?
A: The grade should be selected from the design load of the project; we can supply the relevant compressive strength grade once the requirement is confirmed.
Q: How should the board be stored and installed?
A: Store the boards dry and on a flat base, and install them with tight butt joints using the recommended adhesive or mechanical fixings. Cut them with a standard saw and always follow the project specification and the applicable site safety rules.
