GRP Composite Stable Door FAQs

A thicker skin makes the composite door super-resilient and high-impact resistant, therefore adding yet more strength to the door.
The door slabs are 44mm thick. They consist of 3.8mm GRP outer skins with a thermally efficient condensed foam core.
Yes, all doors are supplied pre-hung in the frame ready to install.
With the split spindle handle system when your door is closed the centre latch will not be released by moving the outside handle. A key is always required to open the door from the outside.
The door threshold is the bottom part of the door frame that you step over to enter the property. The different thresholds finish at different heights. Please see our cills an thresholds brochure for more information.
The cill runs underneath the threshold and protrudes outwards, it is used to deflect the rain water away from the brickwork underneath, preventing damp. The cills come in a 85mm (stub), 150mm and 180mm depth. This is measured from the back of the frame. More details can be found in our cills and thresholds brochure.
All of our doors are made to measure due to all openings being different. Customers can order the size bespoke to their requirement.
Our standard lead time is 10-15 working days although this can be subject to change depending on current stock levels.
Yes, the sizes you enter are the overall sizes for your doorset. This includes the frame and cill (if chosen). E.g. A 900w x 2100h doorset is the overall size including the frame. This means that the door slab itself is smaller then 900w x 2100h due to the frame being incorporated into these sizes. This is also the same for side panels which are also surrounded by frame.
Add On’s are available in 15mm, 35mm sections and are used if the brickwork opening is larger than the maximum frame size we are able to manufacture.
E.g. If you have an opening height of 2170mm and the maximum height we can manufacture a doorset with a cill and pvc threshold is 2159mm, a 15mm add on will be needed. We would reduce the frame height to 2155mm and fit the 15mm add on, this achieves the overall height of 2170mm.

How to Measure

Width

The width should be measured brick to brick at three points - top, middle and bottom of the opening. The smallest of these measurements is taken as the width. Always deduct 10mm from the final width.

Height

The height should be measured brick to brick at three points - left, middle and right of the opening. The smallest of these measurements is taken as the height. Always deduct 10mm from the final height.

Please remember:

Measure in at least three different places and deduct 10mm from both the final height and width measurements - we do not make any fitting allowances on the sizes provided.
Measurements will need to include the frame, cill and any frame extensions required.
All dimensions to be supplied in Metric (mm) and all designs are to be viewed from the outside.
Always check your measurements at least twice to ensure you have the correct size.
Ensure the frame size is smaller than the brickwork opening.
Do not measure your existing door or frame, but measure the brick opening.
