Roof Waterproofing

100mm Kingspan Thermaroof TR26 performs effectively with most mechanically fixed single-ply waterproofing membranes.

Water Vapour Control

Installation Guidelines: New Build Roofs: When applying Kingspan Thermaroof® TR26 to new build roofs, a separate vapour control layer is typically recommended unless the product is used with a sealed metal deck. A condensation risk assessment should be completed for each installation to verify appropriate specification.

Refurbishment Projects with Existing Insulated Flat Roofs or Insulated Steel Faced Composite Panels: For renovation work involving additional roof insulation over existing insulated flat roofs or insulated steel faced composite panels, U-value calculations and condensation risk analysis are essential. These evaluations determine appropriate insulation thickness for meeting thermal requirements whilst preventing interstitial condensation.

Installation over Existing Bituminous Waterproofing Roof Membrane: When Kingspan Thermaroof® TR26 is installed over existing bituminous waterproofing membranes in refurbishment applications, the membrane can function as a vapour control layer if it remains in sound, watertight condition. Where the membrane is compromised, an independent vapour control layer must be installed.

Minimum Requirements for Separate Vapour Control Layer: Where a separate vapour control layer is required, specify a 1000 gauge (250 micron) polythene sheet. All joints must be overlapped and sealed using double-sided self-adhesive tape for effective performance.
