The T Deck panel is moulded from lightweight closed cell expanded polystyrene to a density of 17kg/m3. The profile has been to suit existing pre-stressed beam profiles.

They are used in place of standard building blocks between the floor beams and as the insulation value is more than three times better than even the most efficient lightweght thermal block, no further insulation is required in the floor structure. The panels are very easy to handle and their design facilitates very easy installation.

Tdeck panels in conjunction with pre-stressed concrete beams provide excellent insulation properties, with 'U' values of 0.08W/m2K or less being achievable, dependant on floor area and perimeter of the dwelling.

Because the design of the EPS infill panel minimises cold bridging at the floor beam the theoretical design performance is delivered in practice. The very low 'U' values met with this system assist in meeting the more stringent thermal requirements of the new Building Regulations to Part 'L' and unlike other systems, EPS does not degrade over its lifetime.
