Lonsdale Patent Glazing & Rooflights

Located in a West London conservation area, the existing property required updating by remodelling the kitchen and dining room that suffered poor connection to the rear garden. North facing, these rooms received little daylight from the modest sized windows. It was a dark and dingy space.

ThermGard-R aluminium glazing bars for timber rafters were used to provide a maintenance free and weather-tight glass rooflight to create extra space at this family home in Bethnal Green, London

The States of Jersey were keen to refurbish the glazed roof at Central Market, St Helier, but had to work closely with traders to ensure the minimum of disruption. Stallholders were also concerned about solar gain during hot summers. At the same time, they were wary of the usual tinted glass options that may have cast colour onto their different food markets and flowers. The natural beauty influences customers buying decisions.

Lonsdale were tasked with providing a new low profile glazing bar compatible with the needs of the photovoltaic panels and at the same time meet the requirements of English Heritage

A rooflight over the Cast Court installed in the Seventies had pretty much ‘given up the ghost’ and several leaks were apparent. There had been a history of glass cracking apparently without reason, which we attributed to thermal stress and poor edge cutting of the laminated glass. It was time for renewal.
