Glazing and security across both ranges
Our composite doors carry decorative glazing from our lovely local suppliers, Martindale's and Glasscraft, with bevelled, leaded, etched and contemporary geometric designs available. Solid cores are available and offer the best security if that’s your client’s main priority, with hook bolts and anti-snap cylinders included regardless.
Our uPVC entrance doors use the same glass suppliers, so fitters can offer the same decorative options including Georgian bars, frosted patterns and leaded designs. Security includes multi-point locking, reinforced steel keeps, hook bolts and anti-snap cylinders, with Secured by Design compliance available.

A full range of colours
Composite doors are offered in solid shades, woodgrain effects, dual-colour finishes and selected RAL options. Our uPVC doors share most standard colours but add foiled finishes such as Chartwell Green, Irish Oak and Rosewood, especially great if you’re looking for a convincing timber alternative.

Contact UsWhy fitters specify our entrance doors
Our composite doors use DoorCo GRP slabs. When it comes to the core, you’re spoilt for choice. We specify composite entrance doors with foam, solid timber or hybrid cores, each great for their own reasons. They’re truly bespoke, so you can create any door you’d like.
Our uPVC front doors use Eurocell multi-chamber profiles, so thermal efficiency is promised. uPVC should be affordable, and we’ve made sure that is the case, but without the compromise of quality. Fully welded for strength and finished with minimal maintenance foils.

What fellow trade professionals say about us
Honest feedback from the installers, builders and double glazing companies we supply day in, day out.
Had both front and back stable doors fitted recently, and I have to say the men that came to fit them were really good, pleasant, efficient and did a great job! I am really pleased with my doors and the way the men conducted themselves; they are a credit to Alpine – thanks again.
Carol Marshall
I can’t thank the team at Alpine enough for all of the hard work on your build. They were great from the start, being really helpful through the quote process and in advising. The fitting team worked so hard to make sure everything was perfect, and nothing was too much trouble. We are so happy with Alpine. The results really speak for themselves, and we would not hesitate to recommend them to anyone!
Kate Oakes
We recently renovated a small cottage and needed to consider the traditional look and feel of the property, Alpine Windows and Doors were brilliant, listening to our requirements, we ended up with 6 sash windows and a new composite door all in a non standard colour, which was no problem. from placing the order to the completion of the installation nice and smooth, 5 weeks time frame, fitted perfectly with our project, would highly recommend
Tom Crowe
Excellent service from start to finish. They made the process from colours to design easy, nothing was too much trouble. Lovely polite staff and fitters. Fitters turned up on time and finished to an exceptional standard (I am a perfectionist!) left my home clean and tidy and removed all old frames and doors. Couldn’t fault them at any stage and would highly recommend them. I would give more than 5* if I could.
Sarah Wood
Peter at Alpine has done the windows and doors at both our offices and my home. The service was very professional, fast and competitive price wise. I had a combination of Aluminium bi folds and French doors with UPVC windows. I cannot fault the quality. Very happy to recommend for both domestic and commercial projects.
