Built on Tradition, Driven by Innovation Since 1792.

Founded in 1792, Don & Low began as a small woven textiles manufacturer in Scotland, gradually expanding its operations and diversifying its production capabilities. Through strategic investments in technology and a relentless pursuit of quality, Don & Low has evolved into a leading vertically integrated manufacturer, specialising in producing construction membranes, geotextiles, and industrial textiles & yarns. The company’s dedication to innovation is evidenced by 47 registered patents and trademarks and over 400 products, reflecting a commitment to staying ahead in the industry.

Embracing change and pushing the boundaries of innovation have been the guiding principles of Don & Low’s progress, helping the company stay ahead of industry trends and meet the shifting needs of its customers. Today, Don & Low is a trusted name synonymous with quality, reliability, and innovation, poised to continue its legacy of excellence well into the future.

Specified membranes for the construction industry

With a strong focus on performance, durability, quality, and price, Don & Low has established its position as the UK leader in nonwovens for more than 30 years. So, when it comes to specified roof, wall, floor, and site protection membranes, Don & Low has the construction industry covered. The company’s flagship construction membrane, Roofshield®, illustrates Don & Low’s commitment to excellence. With over 25 years of industry-trusted performance, Roofshield® is a leading air-permeable pitched roofing underlay designed to allow the passage of moisture, eliminating the need for roof ventilation. In addition to Roofshield®, Don & Low provides a complete line-up of membranes for brick and block, timber frame or steel frame applications.

Don & Low’s advanced roofing underlays, which include Roofshield®, RoofTX®, and MultiTX®, enhance the performance and longevity of roofs, making them a vital component of every building. Breather walling membranes such as Reflectashield® and Frameshield® improve the efficiency and durability of walls in various applications, while vapour control layers like VapourTX® play a key role in regulating moisture and temperature within structures, ensuring a comfortable and energy-efficient indoor environment. Don & Low also manufactures flooring membranes like FloorTX®, as well as temporary site protection materials, helping to keep construction sites intact during the building process.

Having a single point of contact for all membrane needs allows construction industry professionals to save time and effort. They can also save money since pricing is highly competitive. Additionally, Don & Low’s customers can streamline logistics and inventory management, minimising inventory losses or project disruptions due to stockouts. Don & Low combines all of the above with an outstanding team of experts who can offer valuable advice on several topics, including membrane selection, installation guidance, U-value calculation, and technical information.

Proudly made in the UK

Being a vertically integrated UK manufacturer means that every step of Don & Low’s production process, from feedstocks to finished membranes, is produced in-house. This level of integration allows the company to maintain the highest standards of quality, consistency, and sustainability throughout its operations.

Don & Low’s construction membranes are fully recyclable and contain recycled materials, and the company also has an operational in-house recycling programme. Additionally, Don & Low can provide Environmental Product Declarations (EPDs) for their membranes, which transparently report objective, comparable, and third-party verified data about their environmental performances from a lifecycle perspective.
