Prestressed Concrete T beams manufactured in 150mm or 225mm depths in 50mm increments with high strength expanded polystyrene insulation blocks.
Insulated Flooring products are manufactured from environmentally friendly expanded polystyrene. EPS is a very sustainable product and an efficient use of natural resources, for every 1 kilogram of oil used in the manufacture of EPS, 150 kilograms can be saved in heating oil over a fifty year period.

Lynx warmfloor will help to enhance the thermal performance and efficiency of a building and can achieve ‘U’ values as low as 0.10 The “U” value is a measure of how easy it is for heat to pass through the fabric of a building measured in W/m²K, that is heat (watts) passing through each square metre (m²) for each 1⁰C of temperature difference. Warmfloor can be specified with a range of “U” values that will ensure the building meets its thermal efficiency target. The table gives the U values based on Perimeter/Area (P/A) using either standard white EPS or grey EPS. Grey EPS has added graphite which improves its insulating properties. The thermal performance of the floor can be improved by simply increasing the thickness of the topsheet.
A thermal bridge is an area of building construction which has a significantly higher heat transfer than the surrounding materials, this can occur at the junction between the floor and the wall reducing the thermal efficiency of the building. The measure of this heat loss at the thermal bridge is known as the PSI (Ψ) value measured in W/mK The use of Lynx warmfloor can result in reduced PSI values much less than Accredited Construction Details of 0.16 W/mK increasing the thermal efficiency of the building.
