Choosing the Right Membrane for Your Project

3 mins

Experts at Don & Low highlight the essential role of roofing membranes and the benefits of their diverse offerings, noting that "when skilled roofers pair their work with the right roofing underlay, you can be confident in the outcome…"

Even though roofing membranes are concealed once a roof is finished, their significance is unquestionable. These membranes serve as a secondary defence against the elements, enhancing the protection offered by roof tiles. Roof tiles act as the primary armour, but they are not infallible. Wind-driven rain can seep through tile gaps, leading to structural damage, mould, and interior decay. The synergy of skilled roofers and the right roofing underlay ensures all-encompassing protection, providing a sense of security.

Roofing membranes do more than prevent water ingress; they enhance a building’s energy efficiency, provide an additional barrier against wind and snow, and offer improved breathability and UV protection. So, which membrane suits your roof best? Let’s explore the offerings from Don & Low, a UK-based manufacturer known for creating Roofshield® since 1996.

Roofshield®

Roofshield®, the pioneering air and vapour-permeable roofing underlay that entered the market nearly 30 years ago, has earned a reputation for trustworthiness through continuous use and rigorous testing. It offers superior secondary protection against rain, wind, and snow while allowing moisture to pass through, significantly reducing interstitial condensation in pitched roofs. This innovation has eliminated the need for roof space ventilation in cold, warm-pitched roofs, revolutionizing the industry. Roofshield® is certified by the BBA and NSAI, a testament to its reliable performance.

RoofTX®

The RoofTX® range includes vapour-permeable, air-barrier roofing membranes that allow moisture passage while resisting air penetration. This range features six distinct products varying in weight and design, catering to different roofing needs across the UK. Suitable for fully supported or unsupported cold and warm systems, RoofTX® offers a lightweight alternative to traditional bituminous felts, maintaining flexibility even at low temperatures. The RoofTX® family is certified by the UK BBA and the NSAI for the Irish market, ensuring high quality and performance. The RoofTX® range not only provides excellent protection against the elements but also offers a lightweight and flexible solution, making it a valuable choice for your roofing needs.
