Large Modular Linked Glass Flat Rooflight

Our modular linked glass rooflight offers a high-quality solution that is easy to install and creates seamless, continuous lighting over large spaces. With each module spanning up to 3.8m in length and being factory-assembled for convenience, you can save time on installation.

The modular design also ensures thermally broken aluminium frames are used for improved energy performance. For added protection and longevity, these frames are powder coated too. The modular units are then structurally glazed and double glazed for further durability and efficiency.

Whether you’re looking for the perfect lighting solution for commercial or domestic purposes, our modular linked glass rooflight provides unbeatable quality without any restrictions on length or size. With its modern design and professional finish, enjoy a product that will last for years to come.

Fitting and Measurements

Before the manufacturing starts for this product, drawings are submitted for approval. The dimensions of your external upstand (timber) will determine the size we provide.

Full instructions for fitting can be found in the PDF at the foot of this page and below.

To ensure there is adequate drainage between each module and to stop water ponding and debris accumulation, installation requires a longitudinal pitch of 0-15° and a lateral pitch of 2-35°*. Where there are opening modules on the rooflights, the hinges should be situated on the rooflight span ridge.

*Note: some of the larger installations will need a pitch which is a minimum of 5°.
