## Description

18mm thick OSB loft boards, designed with precision to elevate your attic space with durability and ease of installation. Crafted to meet the highest standards, these panels boast various features and benefits tailored to enhance your loft experience. Features & Benefits: Tongued and Grooved Panels: Say goodbye to complicated installations. Our OSB loft boards come with tongue and groove along the two long edges, ensuring seamless fitting and a secure, professional finish. Sturdy Support: Designed for reliability, these boards require short edges to be supported on the joists, enhancing stability and longevity. Stagger joints reinforce structural integrity, offering peace of mind for years. OSB3 Grade: Compliant with En 300 standards, our panels guarantee the quality you can trust. Engineered to withstand the rigours of attic environments, they provide superior performance even in challenging conditions. Formaldehyde-Free: Your health and well-being matter to us. Our loft boards are crafted with zero-added formaldehyde, ensuring a safe and healthy living space. Certified by FSC chain of custody, you can rest assured knowing your choice supports sustainable forestry practices. Expansion Gap: To prevent potential issues, a minimum 10mm expansion gap is recommended at all rigid upstands. This allows for natural movement and accommodates environmental changes. Non-Habitable Attics: While perfect for storage and access areas, our loft boards are not suitable for habitable attic rooms. Before installation, it is essential to ensure your ceiling joists are suitable for load-bearing applications. Transform your attic into a functional and organised space with confidence with our 18mm thick OSB loft boards.

This isn't bad if you don't drive and can have it delivered. As its easy to lay and work with. But very disappointed when I found out that you can buy the same stuff for £75 in b&q. So shop around
