Composite Doors

We offer a quality selection of made to measure front and back composite doors. They are suitable for use as either a front door or a back door. These composite doors are tailor made to the sizes you require, and so can be manufactured to fit any sized door opening.

These composite doors come in many designs with a variety of glass styles and patterns, colours and extras.
They are quality doors, whilst also being inexpensive. These doors are offered as a DIY product and the doors are designed for self installation.

With our interactive door pricer, you can order your composite doors online, selecting the door style, colour, glass patterns and any extras wanted.

Side panels are available, and use the same composite door frame and so will match the colour of your doorframe perfectly. They are available glazed, or can include a matching composite infill panel.

The glazed panels are internally glazed and, unless specified, will automatically come with the same glass pattern as the main door, so if you ordered 3 Drop Diamond on Cotswold, then Cotswold would be the glass pattern that is used in the side panel. Glazed panels can also be fitted with the unique composite transom section.

Composite panels are a fixed size of 466mm wide.

The side panels are attached to the door using heavy duty 20mm aluminium coupling sections, which are then clad in PVC.

These side panels can be glazed with any of the glass deigns available.

These GRP (glass reinforced plastic) composite doors are supplied and delivered on a nationwide basis.

Measuring Guide

Measure the width of the door opening at the top, middle and bottom of the brick work opening. Take the smallest of these three measurements, and then we recommend that you deduct 10mm to allow for easy installation.

Measure the height of the opening at both the left side, center, and the right side, from top to bottom between lintel and brick/stone threshold. Take the smallest size of the three and then we recommend that you deduct 10mm from this size to allow for easy installation.
These are our recommendations only, you must satisfy yourself that this meets your criteria as we cannot be held responsible for any mistakes made.
