Slenderpane – Slimline Heritage Double Glazing
At Slenderpane® we manufacture slim glass units, for trade customers only, that allow the use of thermally efficient Slim Double Glazing where only single glazing would normally be allowed by planning and conservation officers.
Comprising top quality components, the high specification Slim Double Glazed Units (commonly known as slimlite or heritage units) have ultra slim sightlines that allow elegant, traditional fixed glazing bars to preserve the period character of the building, whether listed or within a conservation area.
Slim units are most commonly 11mm (4 x 4 x 3), 12mm (4 x 4 x 4) and 14mm (4 x 6 x 4) and sightlines are a standard 7mm or 6mm with the Heritage spacer.

"I’ve been very impressed so far and with a 7mm sight line, your 10 year guarantee it gives me confidence, so much so I’ve asked him to do several more windows. I’m sure you will look after him, and I’m grateful that both he and your company exist to keep older buildings going and not simply rip out perfectly good wooden frames etc. well done!"
David George-Powell, Buckinghamshire
"I have seen a lot of units , I have been around the glass industry all my life. My dad owned two glass shops and was in the business for 61 years."
"The packing crate was a bit damaged but I think there is no damage . We used to put a glass fragile sticker on , the delivery drivers seem to understand that better. He thought it was a machine. Thanks for your speedy service hope to deal with you in the future."
