Slim Cavity Glazing for Letchworth properties
The hard part of Slim Cavity Glazing in Letchworth is not the making, it is the measuring. The housing here is largely garden city stock, Georgian market town frontages and commuter-belt detached housing, and that shapes what will actually fit. Add moderate rainfall with cold inland frosts to that and frost damage to end grain and swelling on unbalanced-finished units becomes the usual trigger for replacement. What we concentrate on is getting a sealed unit into a historic sightline without bulking it out.
Every job is measured on site first, because drawn sizes and built sizes are seldom the same. Send what you have, even if it is only a phone photo, and we will take it from there.
One thing that catches people out here: garden city areas carry design codes that restrict window style changes.
