We know timber windows inside and out; we’ve been crafting them since 1884 through five generations of Barnsdales. Until recently, we have slightly underestimated the breadth of knowledge we have gleaned in those 137 years, passed from generation to generation. Being so much a part of our DNA, we have taken it for granted.

We have decided to do something about this, realising that we actually have a lot of useful information to share with architects and specifiers, in fact anyone that wishes to understand the science and beauty of what we do.

Covered a very wide area of expertise in a single session

Our Barnsdale How to Specify series is an ongoing project designed to share everything we know about timber windows and doors. It is an ever growing knowledge base that will take various forms including CPDs, CPDi, “How to” Guides, Blogs and webinars etc.

Our motivations aren’t entirely altruistic, the better you know timber windows and doors, the more you will appreciate what we do and how it differs to what other joinery manufacturers do! Keep coming back to see what the latest words of wisdom are being imparted.

Of all the CPD events I’ve attended in the last 12 months, this is up there with the best
