Eco Inverted Roof Board

High performance CO2 Blown, CFC/HCFC free extruded polystyrene insulation

Eco Inverted Roof Board is a high performance rigid extruded polystyrene insulant of typical density 30 kg/m³, with a smooth, dense skin on both faces. Eco Inverted Roof Board is manufactured using CO2 as the blowing agent and has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).

  • High performance rigid extruded polystyrene insulation - thermal conductivities as low as 0.02 W/mK
  • Protects waterproofing membrane
  • Minimal water absorption
  • High compressive strength
  • Withstands freeze/thaw cycling
  • Compatible with green roof systems
  • Resistant to the passage of water vapour
  • Easy to handle and install
  • Ideal for new build and refurbishment
  • Non-deleterious material
  • Manufactured with a blowing agent that has zero ODP

Storage Conditions

The recyclable packaging for Eco Inverted Roof Board should not be considered adequate for long term outside protection. Ideally boards should be stored inside a building.  Eco Inverted Roof Board should be stored flat in ventilated areas and protected generally from accidental damage, contact with volatile solvents, flames and extended exposure to UV and sunlight.  If stored outside for more than a few weeks, boards/packs must be covered with a pale pigmented plastic sheet. Eco Inverted Roof Board should not be left in the sun, covered by either a transparent or a dark plastic sheet, since in both cases, board temperatures can build up to a level hot enough to appreciably alter their dimensions or warp them.

Technical Information

Resistance to Traffic Load

> 300 kPa at 10% compression

BS EN 826:1996

Reaction to Fire

When the boards are used in the inverted roof concept and ballasted with aggregate (minimum depth of 50 mm) the roof may be considered to be of designation AA (low vulnerability in Scotland) and therefore meets or satisfies the requirements of the national Building Regulations.

Application

Application steps

SUBSTRATE PREPARATION

The waterproofing membrane must be fully cured before the Eco Inverted Roof Board Insulation boards are installed.
