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
