Product Description

Roofshield Air and Vapour Permeable Breathable Membrane – 1m x 50m

Roofshield is the industry’s leading air and vapour permeable roofing underlay, earning over 25 years of trust through continuous use and rigorous testing. This innovative three-layer membrane, with a patented Meltblown core, allows the passage of moisture to significantly reduce the incidence of interstitial condensation in pitched roofs.

Roofshield provides a superior secondary barrier for roofs to protect against the ingress of rain, wind, and snow. When installed in cold-pitched roofs, Roofshield eliminates the need for roof space ventilation, since moisture diffuses through the underlay. As a testament to its performance and reliability, Roofshield is certified by the BBA in the UK for use in unventilated cold and warm-pitched roofs, in both fully supported or unsupported roofing applications.

Launched in 1996, Roofshield was created by Don & Low, the UK’s only vertically integrated manufacturer. Don & Low remains the sole manufacturer of Roofshield until today, with unchanged specifications, meeting the highest international quality standards. Thanks to its unparalleled combination of physical properties, Roofshield continuously outperforms not just competing roofing underlays but conventionally ventilated roofs as well.

Rendering away the need for roof space ventilation, the use of Roofshield yields substantial savings in both labour and material costs. Distributed directly by Don & Low, customers can now enjoy a multitude of benefits and experience construction membrane excellence, made in the UK.

Roofshield Air and Vapour Permeable Membrane features:

  • Vapour Permeability
    With a vapour resistance of 0.065 MNs/g and an Sd-value of 0.013m, Roofshield stands out as one of the most vapour-permeable membranes available.
  • Air Permeability
    Facilitating air movement and moisture diffusion, Roofshield prevents condensation, dealing adeptly with higher moisture levels during building drying periods.
  • Uniform Airflow
    Roofshield’s air permeability ensures more consistent airflow through non-ventilated roofs compared to roofs ventilated per BS5250, without the need for elaborate ventilation hardware.
  • Water Resistance
    Rated W1 under EN13859-1, Roofshield can endure a water column of over a meter without leakage, providing temporary weather protection to the building envelope for up to 3 months when exposed.
  • BBA Certification
    Fully certified for both non-ventilated warm or cold roof applications since 1996, Roofshield maintains its position as the first membrane certified for use in cold non-vented roofs.
  • NHBC Acceptance
    With a certified air permeability of 34.4m3/m2 h.50Pa, Roofshield eliminates the need for additional high-level ventilation on NHBC-approved projects, ensuring consistent specifications across diverse projects.
  • No Vapour Control Layer (VCL) Required
    Uniquely, the BBA explicitly states that a vapour control layer is unnecessary for non-ventilated cold-pitched roof constructions using Roofshield.
  • BS5534 Compliance
    Independently tested and compliant across the UK, Roofshield, without the need for high-level ventilation or a vapour control layer remains the simplest and most cost-effective method to meet regulatory standards.
