Advice + Guidance
Adding the ultimate contemporary 'wow' factor time and time again, you can count on an SEH BAC flat roof extension for durability, longevity, and outstanding thermal insulation too. Depending on the amount of glazing it contains, a modern flat roof extension can considerably reduce your energy bills. Able to achieve outstanding U-values as low as 0.14W/m2K, the roof lantern incorporates thermally broken aluminium sections; delivering the look of a classic orangery without ever having to compromise on present-day efficiency.
Prepared for the worst of the weather, its strength shines through the fact it can span up to 5.8m above slimline bi-fold or sliding doors without costly and unappealing additional support. It also has a pre-manufactured ‘fall’ system to ensure water drains away efficiently.Get a price
