Cellular Glass Insulated Raft Foundation U-Value and Cost Quote Calculator

Advantages of Cellular Glass

For some specialist applications, cellular glass insulation may be the preferred material. The advantages of cellular glass are:

Fully fireproof and rated to EuroClass A1.
Waterproof due to closed cell structure.
Highly durable and does not deteriorate over time, even in harsh conditions.
No risk of vermin attack.
Has a lambda value of 0.054W/m.K.
High compressive strength of 700KPa.
Does not suffer from compressive creep.

The only drawback of cellular glass is that it is much more expensive than XPS. It is therefore mainly used only in specialist and industrial applications.

Section 1: U-Value Calculator

Soil type*(If unknown, assume clay soil)

Is this raft for a basement?*(Either full basement or partial walk out basement)

Exposed internal perimeter (m)*

Internal floor area (sq.m)*

Type of structure above ground

How many storeys are being built on this raft?

Has a structural engineer completed a design for the raft?*

Yes

Not yet

Select the depth of concrete slab specified by a structural engineer (or assume 250mm)*

Select the depth of cellular glass insulation to see the U-value of the floor slab*

Would you like to improve the U-value by adding a layer of XPS under a screed above the slab?(This will also reduce the cost for the same U-value. Cellular glass is more expensive than XPS)

U-Value =
W/m²K
