MultiTX® Maxi: The Only Heavy-Duty Barrier Roof Underlay with BBA Certification Delivers Proven Performance
Don & Low, the UK's renowned vertically integrated manufacturer, is proud to announce that MultiTX® Maxi, the new, heavy-duty barrier roof underlay, has been successfully assessed by the BBA. MultiTX® Maxi is now the only heavy-duty barrier roof underlay on the market holding a BBA Agrément Certificate. Part of the extended MultiΤΧ® range, MultiTX® Maxi is a high vapour resistance, air and liquid barrier underlay for use in pitched roofs. Weighing 190gsm, MultiTX® Maxi provides enhanced durability and superior protection against the elements, helping to prolon the longevity of the roof. MultiTX® Maxi is a modern alternative to traditional bituminous-based (type 1F) roofing felts with excellent low-temperature flexibility while also being resistant to water penetration and stabilising against UV degradation.
The BBA Agrément Certificate is a mark of excellence based on rigorous national and European standards that validate a construction product’s specialist formulation, capability and uniqueness. MultiTX® Maxi has undergone a thorough evaluation that has quantified its performance. The BBA has determined that the new MultiTX® Maxi is well suited to its intended use and can satisfy all relevant requirements of the essential building regulations.
Will Campbell, Head of Sales at Don & Low, commented: “The BBA Certificate of MultiTX® Maxi represents a long history of technical competence and countless successes in our Research and Development and testing departments. As a vertically integrated manufacturer, Don & Low maintains total control over every step of the in-house production process. This allows us to maintain the highest quality standards and consistent product performance, resulting in innovative and cost-effective solutions tailored to the needs of the construction industry.”
The extended MultiTX range of barrier roof underlays now consists of four products: MultiTX® Plus (116gsm), MultiTX® Pro (145gsm), MultiTX® Maxi (190gsm) and the specifically engineered for integrated solar roofs MultiTX® Solar.
