Concrete Floors
Floors can offer excellent thermal performance by incorporating
high levels of insulation.
Slab and perimeter insulation
Concrete floors such as slab on ground can be
designed to achieve excellent thermal performance.
A well-insulated concrete slab will contribute to the
building’s thermal envelope, save energy and help to
reduce energy costs.
Under slab insulation
ClimaFoam XPS Board has high compressive strength
®
Perimeter insulation
The addition of perimeter insulation will complete the
thermal envelope and provide a simple and effective
method of improving the performance of the concrete
floor. ClimaFoam XPS Board can be retrofitted to
existing properties or installed before or after the
concrete is poured in new build applications.
and moisture resistance, which makes it ideal for ClimaFoam XPS Board should be installed as a
installation under the concrete slab to prevent thermal continuous barrier around the slab edge and cover as
loss through the ground. ClimaFoam XPS Board is much of the footing as possible. Earth can be backfilled
available in a range of thicknesses and can be multi- directly against the insulation and the exposed
layered to achieve high thermal resistance. surface should be protected with a plaster finish or a
suitable sheet material.
Under floor heating
Under floor heating is a popular build consideration
when using a concrete slab. Installing ClimaFoam
XPS Board under the slab is ideal to ensure optimal
performance of the heating and Building Code
requirements are being met. This will also help to
minimise heat loss and reduce energy costs.
Underfloor footings and thickenings
The high compressive strength of ClimaFoam XPS Board
makes it suitable to be placed under footings and slab
thickenings. For details, please consult the designer or
the project engineer.
