I thought I would get in touch following installation of your glass by Chris of Sash Window Doctor, Portland, Devon. We never expected huge differences in temperature with this type of slim glazed units so only gave Chris a couple of windows to see if your website claims stand up. The honest answer is yes!
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!
Many thanks, Mr Hothersall, Somerset.
