Applications

ECO Sential Plus – Double Sided Insulation is suitable for a wide range of roofing applications, including:

• Residential homes and housing developments

Installation Recommendations

For tiled roofing structures, ECO Sential Plus should be installed horizontally across the rafters, beginning at the eaves and working upwards towards the roof ridge. Adjacent layers should overlap by a minimum of 150 mm, with tiling battens secured over the insulation.

For industrial and metal roofing applications, the membrane should be installed over appropriately positioned straining wires and securely fastened according to the manufacturer’s installation guidelines.

All overlapping joints should be sealed using aluminium tape to help prevent movement, reduce flapping noises and safeguard against fire and smoke spread.

The insulation should not be left exposed overnight without roof covering, as wind and adverse weather conditions may cause damage.
