Specially designed for sealed units that are hard to reach, such as conservatory roofs and isolated windows, our naturally self-cleaning low-maintenance glass features a coating on the external surface that harnesses UV light and rain to efficiently break down and rinse away dirty residuals.
Produced with Planitherm natural self-cleaning glass, our sealed units will maintain cleaner for longer even in highly polluted areas.
Noise Reduction Sealed Units
Our noise reducing units are available in a choice of formats depending on your specific requirements, ranging from basic units which combine glass panes with different thicknesses to the specialist laminated glass featuring transparent plastic interlayers between two sheets, which keeps unwanted noise out.
Chosen by many homeowners to add character to their properties, our decorative glass comes in a multitude of standard choices – from traditional motifs to contemporary styles, as well as bespoke designs, created to your customers’ exact requirements.
Thanks to our craftsmanship and state-of-the-art machinery, we’re able to supply high performance decorative glass to help you take advantage of this market trend.
Our decorative glass comes in a wide variety of styles, ranging from stained and coloured glass to bevelled and leaded in a large variety of designs.
We offer both Astragal and standard Georgian bars, for those who seek a more traditional look. The Astragal bars (28mm wide) are attached on both external surfaces of the unit, to give the impression of small panes of glass, while the standard Georgian bars (18mm or 25mm wide) are fitted between the glass panes.
Our obscure and patterned glass offers privacy in a choice of beautiful designs, while still allowing plenty of natural light into a room.
Although mainly used in areas that require privacy, our obscure glass is often simply a style choice for homeowners wanting something different.
We use the Planitherm range of Textured Glass, with designs ranging from classic to contemporary that offer different levels of obscurity.
