The Litecast GT(2) system can achieve the following Uvalues:
- GT18 - approx. 0.18W/m²K - Poly Depth 180mm (Sits on the shoulder of the beam and protrudes above the beam by 80mm)
- GT15 - approx. 0.15W/m²K - Poly Depth 230mm (Sits flush with the bottom of the beam and protrudes above the beam by 80mm)
- GT12 - approx. 0.12W/m²K - Poly Depth 250mm (Sits on the shoulder of the beam and protrudes above the beam by 150mm)
Litecast's GT(2) system has various advantages, these include:
- A cost effective alternative to traditional beam and block.
- Unlike alternative EPS flooring systems the GT system does not require a separate layer of sheet insulation - Reducing labour time and associated costs.
- Unique loadbearing white polystyrene rails, that allow identification of the floor beams following installation.
- The unique multi-rail fill the voids between multiple beams with polystyrene, negating the need for any grout and minimising cold bridges.
- Can be used in conjuction with micro-fibre reinforced concrete.
- Reduced dig out required - saving time on site and money on spoil removal
- Reduced dwelling emission rates (DER).

The Litecast GT(2) system is our latest innovation in thermally insulated structural ground floors. The system has been developed with ease of installation, thermal performance and structural details in mind. The system comprises 150mm pre-stressed concrete floor beams which are infilled with large lightweight Expanded Polystyrene (EPS) panels. The GT panels are supplied along with white load bearing rails, both of which are moulded to suit the profile of the concrete beam. Unlike competitors flooring solutions, the Litecast GT(2) system does not require any additional sheet insulation, thus significantly reducing installation time. The GT panels come in a range of depths that have been specifically designed to match coursing levels, thus giving a flexible approach to achieving different 'U'values whilst ensuring a quick screeding process.
