Flat Sliding Rooflights

Sliding Rooflights are the ideal solution for regular rooflight access, or for larger ventilation requirements.

Bringing the outside, inside

Next Generation Rooflights manufacture our sliding Rooflights from our base in East Anglia. They are the highest performing Sliding Rooflights on the UK Market, testing in accordance with the CWCT Requirements – tested past the 600pa resistance requirement, up to 1050pa.

All our sliding rooflights can be controlled via your smartphone or your smart speaker.
We offer larger sizes as standard than any other glass sliding rooflight on the market.
We can provide CWCT Class 1 & 2 glass as standard.

Bespoke options of all our sliding rooflights, stacking versions and hybrids of our standards are also available, the only limit is your imagination.

Why Choose A Sliding Rooflight Instead Of An Access Hatch?

Access hatches are for occasional maintenance access, whereas a sliding rooflight can allow full stairs below the rooflight giving you regular hassle free access onto you roof terrace.

This is particularly beneficial for those living in cities who have no garden or are unlikely to have access to one. As well as providing a means to access previously unutilised space creating a roof terrace or roof garden, especially as a green space can improve your quality of life.

Sliding Rooflights are suitable for all nominally flat roof constructions and coverings e.g. Single Ply PVC, Fiberglass, lead, copper, zinc and other standing seams and asphaltic material (they are also suitable for Green / Sedum Roofs).

Sliding Rooflight Options

In the UK staircases have a maximum pitch of 42°, so that you can climb them comfortably upright without needing to lean back or crouch forward, a Next Generation Sliding Rooflight opens easily to 42°, this means that you can ascend and descend, carrying food and drink or a small child.

In our clients words:

We recently had the pleasure of working with Next Generation Rooflights on the design, manufacture and installation of a large bespoke mono pitch atrium rooflight. From start to finish, the experience was exceptional. The team demonstrated outstanding professionalism, expertise, and attention to detail throughout the entire process. The rooflight itself was perfectly tailored to our specifications and enhances the natural light in the space beautifully. The quality of the materials and craftsmanship is evident, and we have received numerous compliments on the stunning design. We were particularly impressed with the team's commitment to meeting our deadlines and their ability to navigate the complexities of the project with ease. Their communication was clear and consistent, ensuring that we were always informed and confident in the progress. Overall, we couldn't be happier with the result and highly recommend Next Generation Rooflights for any rooflight installations. Their dedication to excellence and customer satisfaction is truly commendable.

James Hunt, adt workplace

We've been working with the team for quite some years and find their customer care second to none. The products are always on point and manufacturing is flawless. Communication is always swift and informative. All we really want in the rooflight world is, quick answers, good prices, great products, and delivery on time. They tick all these boxes.

Sam Goodwin, Alpha Structures

The Hurlingham Club project demanded a sensitive and technically complex approach, and Next Generation Rooflights proved to be a good partner throughout. From early design development to installation, the NGR team worked with us to deliver bespoke rooflights that both complement the Club’s historic character and improve the quality of the internal spaces. Their technical capability, collaborative approach, and attention to architectural detail were key to the success of the project. We would happily use their expertise on our future projects.

Howard Pye, Associate Director, Jestico+Whiles

We have been working with the team for approximately 3 years now. Their sales and technical team are always very proactive and helpful with any request to quote for projects or alter technical drawings. We use them as their quality of product is unmatched, we look forward to continuing to build the partnership with them over the coming years
