NEW Stylite Passivehaus Foundation Insulation Datasheet

The new Stylite Passivehaus Foundation Insulation datasheet from Styrene Packaging & Insulation Ltd is now available. This eight page guide with typical build up illustrations, installation guide and technical specification is essential viewing for architects, specifiers and house builders looking for thermal and cost saving benefits.

The UK construction industry is currently facing two major challenges, firstly Building Regulations are tightening, requiring more energy-efficient buildings, and targeting zero carbon new homes.

Whilst many conventional buildings designed and built in the past few years are demonstrating a performance gap (poor performance compared to predictions) in terms of energy use, ventilation and thermal comfort. To add to these problems there is also rising energy costs and around 5.5 million households in the UK currently living in fuel poverty.

To solve these problems Styrene Packaging & Insulation Ltd (SPI) have launched a new product - Stylite Passivehaus Foundation Insulation which is a quick and highly effective modular system for building Passivehaus standard foundations to achieve u-values as low as 0.10W/m2K.

Manufactured from high performance Expanded Polystyrene (EPS), the system eliminates the critical cold bridging between the ground and the building, resulting in a much more thermally efficient build.

Delivered to site in modular units consisting of “L” shaped perimeter pieces and flat sheets, installation is incredibly quick and easy. Once in position the amount of concrete required is vastly reduced by up to 60% compared to traditional foundation methods. A choice of EPS grades are available to suit your project thermal and compressive requirements.

The Stylite Passivehaus Foundation Insulation system offers the following major benefits to house builders:

• Eliminate the critical wall-to-floor cold bridge


• Excellent thermal performance 0.10W/m2K


• 60% less concrete required


• Significantly reduces underfloor heat loss


• Modular off-site design and manufacture


• Saves on materials, labour and time


• Lightweight, quick and easy to install
