Read the latest magazine Featured Solutions Membranes Solar Underlay Don & Low Introduces MultiTX Solar: The UK Answer to Solar Roof Requirements 2 May 2024 IN RECENT YEARS, regulatory bodies have introduced stringent standards to ensure the efficiency and safety of integrated solar roofs. From Part L regulations and The Future Homes Standard to the NHBC standards, builders and developers face a myriad of requirements aimed at optimising energy performance and minimising environmental impact. Central to these regulations is the need for proper ventilation within integrated solar roofs – a crucial element in preventing moisture buildup and ensuring long-term durability. Different types of underlay pose varying risks of condensation, with low resistance (LR) underlay potentially increasing condensation risk within the batten space. In contrast, high vapour resistance (HR) underlay, when applied, negates the need for a ventilated counter-batten space, provided adequate eaves and ridge ventilation are maintained, as per BS 5250 regulations.
