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


We’re pleased to announce that from 14 September 2016, we’ll be offering laminated inner pane glass as part of all our standard specification. We’re really excited about this, as this new enhanced specification means our customers will be able to enjoy windows that are stronger, safer and more durable, building on our industry-leading BSI Kite-mark commitment to quality and safety.

So, what is the laminated inner pane, and how does it work?

From now one, our inner pane will consist of two different panes of glass permanently bonded using heat and pressure. The panes will also have a plastic interlayer of polyvinyl butryal (PVB), a perfectly clear material that’s renowned for its toughness.

What are the benefits of this approach?

  • Well, first things first: sun protection. You see, PVB works as an UV filter: you can enjoy the same perfect view knowing that your home is protected from the sunrays.
  • Secondly, PVB is tough.  Even in the unlikely event that an accident causes damage to the inner pane, it’ll be fully contained within the laminate. For skylights this is particularly useful, as it means there’s no danger of glass crystals falling into the room in the event of a breakage. Safety, guaranteed.

And, you can enjoy these benefits without having to worry about your view being interrupted: laminated inner panes are an unnoticeable enhancement.

Indeed, the chances are you’ve probably seen them before. Laminated panes have long been a standard specification for roof lights in schools, museums, universities and other public buildings.This in itself is an endorsement of their safety and toughness: health and safety are key to public spaces, and those in charge of running these buildings rely on this approach time and time again.

Needless to say, our weather facing product range still hold the only BSI Kitemark for a rooflight, so you can rest assured you’re getting nothing but the very best.

If you’ve got any questions about this new feature – which’ll be included as standard in all rooflights ordered from14 September – then give us a call today and we’ll be happy to help.
