In the ever-evolving UK housing market, where building regulations are tightening and performance expectations are rising, roofing membranes are pivotal in ensuring long-term protection, energy efficiency, and indoor comfort. Don & Low's RoofTX® range of vapour-permeable (LR) underlays has been developed to meet these challenges—offering a complete, UK-certified solution that balances high performance with exceptional value.
A Membrane for Every Roof
The RoofTX® family consists of six distinct products, each varying in weight and design to accommodate different application needs—whether in warm or cold-pitched roof systems, supported or unsupported. The range includes standard versions and Conseal options, which feature integrated tapes to simplify installation and ensure airtightness at laps.
Unlike traditional bituminous felts, RoofTX® membranes are lightweight, flexible (even in low temperatures), and engineered to enable moisture passage while resisting air infiltration. This dual function significantly helps prevent interstitial condensation, one of the leading causes of roof failures over time.
Crucially, all RoofTX® membranes are BBA-certified for the UK market and NSAI-approved for Ireland, offering builders, contractors, and developers the peace of mind that comes with third-party validation.
Designed & Manufactured in the UK
With over 35 years of expertise in nonwoven textiles, Don & Low has earned its place as one of the UK's most trusted manufacturers of construction membranes. Based in Forfar, Scotland, Don & Low is a vertically integrated manufacturer - meaning every production stage, from raw material to finished membrane, is managed in-house. This ensures consistent quality, reliable supply, and the ability to tailor products to customer needs.
Don & Low remains less susceptible to international supply chain disruptions by keeping manufacturing entirely UK-based. This enables prompt delivery for projects of all sizes; for those with bespoke requirements, in-house R&D and production flexibility mean that custom solutions are always an option.
Certified Performance
Performance matters, especially when roofing membranes must withstand years of service and varying climatic conditions. Don & Low's commitment to rigorous testing and third-party certification ensures that each RoofTX® membrane delivers proven durability, vapour permeability, and water resistance.
In addition to BBA and NSAI certifications, Don & Low provides Environmental Product Declarations (EPDs) for its complete membrane portfolio. These documents offer transparent, independently verifiedinsights into each product's environmental footprint, allowing architects, housebuilders, and developers to make informed decisions that support sustainability goals and Scope 3 emissions reporting.
Meeting Today's Needs—And Tomorrow's Standards
As the UK construction industry works toward meeting the Future Homes Standard, the demand for building materials that enhance energy efficiency without complicating construction methods is intensifying. Don & Low is committed to staying ahead of this curve.
Through continuous innovation, the company is evolving its product range to support better U-values, airtightness, and thermal performance—all while simplifying on-site installation. The RoofTX® range is central to this strategy, offering robust solutions that align with current building regulations and the industry's forward-looking sustainability agenda.
Moreover, Don & Low's membranes incorporate, on average, at least 20% recycled content—contributing to a more circular construction economy.
