Stylite Cavity Wall Partial Fill Insulation

Stylite Partial Fill Cavity Insulation Boards are manufactured from PlusTherm Expanded Polystyrene (EPS) for use in masonry cavity walls in new domestic and non-domestic buildings with a nominal residual cavity of 50 mm. Stylite PlusTherm is made from graphite infused EPS giving it a high-performance thermal conductivity and will meet Building Regulations for thermal performance.

All Stylite Partial Fill Cavity Insulation is manufactured in accordance with BS-EN-13163:2012+A2:2016. Under a Quality Management System accredited to ISO 9001:2015 and an Environmental Management System accredited to ISO 14001:2015.

Expanded Polystyrene is rot proof, Expanded Polystyrene is not affected by bacteria, moulds or fungi, and will not provide nutrient value for insects or vermin. Expanded Polystyrene does not lose any performance over time and will remain an effective insulation for the life of the building.

Stylite Expanded Polystyrene is hydrophobic and highly resistant to the absorption of water but will allow a very minimal amount of water vapour transfer. Expanded Polystyrene is often utilised with a suitable damp proof membrane or vapour control layer to avoid any unwanted water ingress.

Stylite Expanded Polystyrene will achieve reaction to fire Euroclass F. However, the system classification achieved when installed within a building will generally be considerably better due to use of other construction materials. We also supply FRA grades which contain a Fire Retardant Additive and achieve reaction to fire Euroclass E.

The Stylite Expanded Polystyrene does not contain HFC’s, CFC’s or HCFC’s. Expanded Polystyrene has a Global Warming Potential (GWP) of zero and a low O-Zone Depletion Potential (ODP). Expanded Polystyrene is 100% recyclable.
