Stylite T-Beam is a bespoke expanded polystyrene insulation void former designed for use in conjunction with pre-stressed concrete beams. The panels are lightweight and provide a highly efficient and cost effective method of insulation that exceeds the thermal requirements of Building Regulations Approved Document L. The polystyrene panels are profile cut to suit any concrete beam design ensuring a tight fit which greatly reduces cold bridging. Classed as block type R1, consult manufacturer's literature for further details.

EPS is rot proof and durable, and will remain effective as an insulation for the life of the construction; it is not affected by bacteria, moulds or fungi and will not provide nutrient value for insects or vermin.

Features and benefits:

  • Lambda from 0.030 W/m·K.
  • Reduces cold bridging.
  • Lightweight and cost effective.
  • Can be used on all suspended floors.
  • Quick and easy installation.
  • Used in commercial and residential property.
  • Minimal water absorption and permeability.
  • 100% recyclable.
  • No HFC’s, CFC’s or HCFC’s.
  • Global Warming Potential (GWP) and Ozone Depletion Potential (ODP) of zero.
  • BRE green guide rating: A+.
  • CE marked.
