How Don & Low’s Membrane Innovations Move Modern Construction Forward
W
ill Campbell, Head of Sales at Don & Low, discusses how cutting- edge membrane solutions enhance
durability, effi ciency and sustainability.
Founded in 1792, Don & Low has grown from a small Scottish textile manufacturer into a leading vertically integrated producer of construction membranes,
industrial textiles, and yarns. Driven by innovation and adaptability, we’ve earned a reputation for quality, originality—delivering
reliability, and advanced solutions
to meet evolving industry needs for over four decades.
What competitive advantages does Don & Low hold in a dynamic industry such as construction? What distinguishes Don & Low is our status as a vertically integrated construction membrane manufacturer in the UK, meaning we manufacture all the membrane components. Don & Low oversees every step of the production process to ensure that the Don & Low building envelope provides reliable, consistent performance on which the industry can rely. Thanks to this level of integration, we are strategically positioned to support the sector’s anticipated growth by providing builders,
contractors and
architects the right tools to thrive. Vertical integration also translates into fewer supply chain disruptions and all-year-round product availability for projects, regardless of size, anywhere in the UK. Moreover, we offer unrivalled membrane customisation options and a broad range of professional technical services at no cost.
Since you mentioned the Don & Low building envelope, could you tell us more about your products?
Certainly! Don & Low offers a broad range of high-quality construction membranes designed to meet varied building needs. Our fl agship roofi ng membrane, Roofshield®, has delivered
trusted performance for
nearly 30 years. We also offer advanced roofi ng underlays like the RoofTX® permeable) and MultiTX®

In what ways are you anticipating and adapting to industry needs?
Innovation is in the DNA of Don & Low, driving the company to keep enhancing and evolving its offerings for the construction industry. As a market-led business,

layers. Our range also includes FloorTX® fl ooring membranes and temporary site protection materials—supporting building performance and protecting construction sites throughout the build process.
Given the global push for sustainable infrastructure, how is Don & Low leveraging its expertise to drive innovation and address the specifi c environmental challenges within the construction sector?
The construction industry presents a unique blend of challenges and opportunities that align with our expertise and capacity. As a responsible manufacturer, we recognise construction’s critical role in economic growth and shaping sustainable,
energy-effi cient
living. We develop essential solutions that meet industry needs while supporting a more sustainable future through in-house recycling. The Don & Low building envelope averages at least 20% recycled materials. We also provide Environmental Product Declarations (EPDs) with unbiased, standardised, and independently verifi ed information on our membranes’ environmental impact throughout their lifecycle.
experienced in-house Research and Development (R&D) team is the cornerstone of our innovation efforts. Don & Low’s dedicated team of engineers and scientists focuses on evolving membrane solutions for roofs and walls to accommodate the Future Homes Standard and the ever-more challenging climate conditions. Additionally, we work in partnership with customers and partners to ensure that the company’s innovations align with market demand and deliver tangible value.
How does this translate into product development? Proshield®
exemplifi es the innovative efforts of Don & Low remarkably well, as it empowers architects to achieve airtightness in modular and high-rise construction more effi ciently than ever before. Our brand-new membrane weighs 270 g/m2, with one of its key characteristics being its three-layer structure, featuring an adhesive coating on one side together with a transparent silicone- coated PET release
liner. Placed on the
outside of a structure, Proshield® acts as a water-resistant and airtight barrier whilst still allowing water vapour to escape. Proshield® stands out from conventional membranes by eliminating the need for primers or additional fi xes. It adheres seamlessly to a variety of substrates, including OSB, steel, gypsum board, concrete, aluminium and wood. This adaptability makes Proshield® ideal for use in offsite and high-rise construction, combining straightforward installation with high tensile strength and signifi cantly contributing to a building’s overall performance and longevity. Furthermore, recent R&D advances have led to an enhancement of Roofshield®. Weighing 196 grams per square metre, Roofshield® is the heaviest air and vapour- permeable roofi ng underlay available, translating into even better tear strength, durability and protection against extreme weather conditions.
