Due to the current shortage of aerated concrete blocks, a national house builder wanted an alternative flooring system for a large residential new build housing project in West Yorkshire. The unique
Stylite T-Beam Suspended Floor Insulation system was introduced to the clients design team, who quickly saw the benefits it offered and were quick to specify the system.
The shortage of aerated concrete blocks in the UK, caused by a reduction in the availability of fresh Pulverised Fuel Ash (PFA) is causing long delays on construction sites. A by-product of coal-fired power stations, PFA is an essential ingredient of concrete blocks, giving them their thermal insulation properties. A warm winter, low gas prices and gradual closure of coal-fired plants for cleaner energy sources has reduced the amount of available PFA.
Styrene Packaging & Insulation worked closely with the client and concrete beam manufacturer to design a holistic solution. The unique Stylite T-Beam Suspended Floor Insulation solution comprised of lightweight Expanded Polystyrene (EPS) panels contour cut to suit the profile of the concrete beams. The interlocking EPS panels were installed between the beams with the “toe” extending underneath to provide the all round insulation and eliminating cold bridging. The panels specified were 230mm deep to achieve a U-value of 0.22 W/m2K meeting the clients requirements for Building Regulations. To complete the floor design a macro fibre concrete screed topping of 75mm was specified.
The Stylite T-Beam offered the following major benefits to the client:
- Quick and reliable deliveries
- Excellent thermal performance
- Interlocking panels prevent cold bridging
- Lightweight blocks reduce health and safety concerns on site
- Fast installation reduces labour costs
