Sunsquare: The market leaders in skylight and roof light design and installation

Horizon walk-on glass roof panels

From £906 + VAT

Our BSI Kitemarked Horizon walk-on roof lights are perfect for rooftop areas and terraces as they are built to walk on whilst flooding fantastic levels of natural daylight into interiors below.

Our walk on rooflights are ideal for spaces requiring regular or occasional pedestrian access. The Horizon walk-on range combines technology and safety. These contemporary rooflights enhance levels of natural light into living areas below, whilst passing all the necessary regulations to be walked upon, giving you genuine peace of mind.

Why choose Sunsquare?

Our supremely stylish Horizon walk-on range are the only roof panels that can be walked upon which surpass the world-renowned hallmark of product excellence – the BSI Kitemark.

Our special walk-on specification insulating glass unit – perfect for areas requiring pedestrian access like roof terraces – offers levels of safety and thermal performance like no other roof panel on the market. Its performance against extreme wind loading, weather tightness and air permeability is second-to-none.

Sunsquare takes its role as world-leading skylight designers and manufacturers very seriously and sets the benchmark for the UK skylight industry in many ways:

  • Sunsquare were the first rooflight manufacture to be awarded a BSI kitemark for a rooflight
  • Unmatched thermal performance
  • Raising the bar for product safety and security
  • 20-year glazing guarantees
  • 35-year warranty on upstands
  • Design innovation recognised by the BRE
  • Fast and efficient lead times
  • Strict environmental policies – recycling or reusing 97% of our waste
  • Superb value for money

Supreme thermal efficiency

Each BSI Kitemarked Horizon walk-on rooflight that leaves our factory is manufactured from our extruded aluminium profile which is thermally broken using multiple polyamide insulating sections and factory glazed with our special walk-on specification insulating glass unit.

When combined with a Sunsquare upstand, our Horizon range achieves U-values as low as 0.94 W/m²K. Sunsquare is the only manufacturer to provide structural calculations for our walk-on product range.

The easiest and quickest way to install a Horizon Walk-On skylight is to fit it onto a Sunsquare upstand flush to the flat roof. The timber decking or roof-top paving then aligns with the top face of the glass, leaving a sleek, flawless finish. Our Upstands are optional with every product, but we can’t recommend them enough, simply because they guarantee an easy installation and enough pitch to allow for water run-off.

The real benefit of a thermally broken roof window is that it prevents unwanted heat loss and also guards against condensation from morning dew. Put simply, thermal breaks work to maintain the climatic control of your home without you having even lift a finger!

With the introduction of a laminated inner pane as standard on all our rooflights, we're also leading the way in providing a safer and more secure rooflight with the added benefit of filtering out 99% of the sun’s harmful UV rays.

Every single skylight we manufacture can be made-to-measure for your property’s exact specifications. So if you need an entirely bespoke skylight we can work with you to ensure you get the design and performance you desire for your property.
