What is a flat roof extension?

Available in a number of square or rectangular sizes to suit your individual project, our Flat Skylight is designed to deliver maximum, uninterrupted sightlines whilst flooding the space with warming natural light. Fusing cutting-edge technology with minimalist charisma, these fixed seamless skylights sit flush (flat) to the internal plasterboard, creating a fabulously frameless appearance inside and a modern, streamlined exterior. Our modern flat roof extensions also make the ideal accompaniment to traditionally styled properties seeking classic elegance with a statement-making pitched lantern roof option. Combined with a plethora of bespoke design options, any look can be achieved, and any style of property can be enhanced with an SEHBAC flat roof extension.

    The strongest & warmest flat roof extension available

    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.
