Protect building foundations with Foamglas Insulation
Foamglas is one of the go-to building products for architects and construction companies seeking high-compressive strength insulation, which is both moisture-resistant and fire-rated. Ticking both boxes, Foamglas stands tall as one of the best insulation choices for high-rise buildings.
Suitable for a variety of applications, including underneath blockwork to prevent cold from transferring through the concrete and into the walls, underneath damp-proof courses to prevent moisture from rising into buildings, and flat roof applications where compressive strength is required.
The Foamglas range also includes a variety of accessories, including PC56 adhesive- a solvent-free two-component adhesive used for bonding Foamglas slabs to concrete, masonry, wood and two Foamglas layers together.
There are many Foamglas insulation products available, each serving a different purpose:
If required, FOAMGLAS® can be installed in two or more layers. Easily cut or trimmed with a hand saw blade. non-combustibility.

Frequently Asked Questions
What is cellular glass insulation?
What is cellular glass insulation?
Cellular glass is a lightweight, rigid, and durable insulation system developed by Foamglas. It is made up of millions of completely sealed glass cells and boasts exceptional properties including incombustibility, superior compressive strength, guaranteed water and vapor-tightness, and long-lasting thermal insulation performance.
What is the difference between the T3 and T4?
What is the difference between the T3 and T4?
Foamglas T3 and T4 differ in compression strength and efficiency, with T4 being denser but less efficient in insulation compared to T3. T3 is preferred for applications requiring fire resistance, water resistance, and optimal insulation value, while T4 may be suitable for situations where compression strength is paramount, albeit with slightly compromised insulation efficiency.
What is the difference between the boards and the blocks?
What is the difference between the boards and the blocks?
The main difference between the board and block versions of the insulation is the size.
Is Foamglas fire-rated?
Is Foamglas fire-rated?
FOAMGLAS® cellular glass insulation is non-combustible, doesn't contribute to fire spread, doesn't release smoke or toxic gases, nor produce flaming droplets that can cause injury and contribute to fire development.
It has a melting point in excess of 1,000°C (for thicknesses of 80mm and above, when tested to DIN 4102-17), and a significant portion of its core mass remains after 90 minutes. When exposed to fire, it undergoes vitrification, forming a durable ‘protective layer’ on the surface.
