Please click any of the images to the left, or the testimonial below, in order to view enlarged versions of all these images Dear Protech, My wife and I FINALLY got around to fitting the units you supplied. The installation was a DIY doddle (even for a newly retired couple like us) and the final effect - in both aesthetic and insulative terms - is most impressive. Thanks for the excellent product ! As is usual in houses of the type in which we live, we have a similar upstairs bay and we intend to tackle this too in the not-too-distant future, so you'll be hearing from us again in due course. Before and after photos are attached to this email. Thanks once again. Best regards, Chris & Clare Sheard
