Why is S-Glaze different?

To understand what S-Glaze is, firstly you must understand how glazing is inserted into a regular composite door.

At Rockdoor, instead of using traditional, clip-on cassettes (which are prone to a whole host of problems) to secure the glazing in place, we rely on our unique S-glaze technology.

The technology consists of sealing the glass unit in between two Rockdoor skins, which form part of the door itself and will in turn improve the energy efficiency of your home!

S-Glaze can offer a whole host of other benefits too – It will remove the possibility of any draughts entering your home via the glazing or the possibility of water ingress as a result of faulty cassettes. S-Glaze can also contribute to your door being ‘Secured by Design’ accredited.

*N.B. – To be ‘Secured by Design’ accredited, doors must be manufactured with laminated glazing and include wire mesh reinforcing.

Why choose a Rockdoor with S-Glaze?

Any Rockdoor manufactured with a glazing feature is made with S-Glaze, meaning that burglars will have one less opportunity to enter your home in the middle of the night, when most offences occur.

Conventionally, intruders will look to pry the cassettes from other doors open as a quiet method of breaking and entering. Thanks to our glazing being moulded into the door, S-Glaze does not give burglars a chance.

Glazing cassettes tend to be manufactured using different materials to composite door skins and therefore are prone to fading and discolouration, even in the early days of its’ life – Often needing to be replaced to rectify this problem, which comes at a further cost.

Water ingress can be a common problem for doors that rely on cassettes holding the glazing in place, however, at Rockdoor this will no longer be a problem for you. How can water enter a home through a glazing unit that is sealed in between the two skins? It can’t!

Rockdoor – The ONLY composite door manufacturer to use S-Glaze

Rockdoor is the only composite door in the UK that incorporates S-Glaze, making it truly stand out from the rest and giving more reason as to why it is the best composite door of its kind on the market!
