What is a Composite Door? How to adjust Composite Door hinges?

I thought everybody knew what a Composite Door was, and then this morning i visited a new customer to measure up for a uPVC front door, and she hit me with it (the question, not the door!), "What exactly is a Composite Door?".

So I've decided to write this quick blog to explain what a Composite Door is, and how to adjust Composite Door hinges, another frequent question on our site.

A Composite Door is made from timber, with an insulated internal structure. A typical Composite Door is then finished with a GRP skin, to replicate the look of a traditional timber door. If you look out of your window, somebody in your street probably has a grey one!

GRP or Glass Reinforced Plastic is an extremely tough and hard-wearing composite material used for the skin (surface) of the door. This material has many advantages over uPVC, the main advantage being it's strength.

The GRP skin material is also extremely resistant to UV damage from sunlight, traditional materials such as uPVC can weaken and become brittle over time.

The second question. How to adjust composite door hinges?

This one is more difficult as there are several different designs in use. Generally a composite door hinge has very little adjustment, as once the door is fitted correctly, it should sit squarely in the surrounding frame, and should rarely need to be adjusted.

If you do need to adjust your composite door hinges, try our helpful guide below. If your Composite Door hinges look nothing like the ones in our pictures, call us to book a repair. If you have similar hinges to those in the picture, try these few steps to fix your door. I'm guessing you're reading this because you have a Composite Door which is difficult to close or lock. If this is the case it's always worth trying this quick fix.

Step 1. Open the door fully, and look behind the hinge. You should see some small hexagon shaped holes in the top and bottom of the hinge.

Step 2. Using a 5mm hex key, turn these to adjust the door. You will only get a few millimetres movement using this method, if this doesn't fix the door, move on to step 3.

Step 3. Just above the top adjuster is a flat white plastic cover. CAREFULLY remove this and put it in your pocket.

Step 4. Close the door and look in the top of the hinge. The little white cover you just removed was hiding another adjuster, probably brass in colour. The same as before, using your hex key, turn the adjuster until you see the door moving. Again you will only get minimal movement on this but it should be enough to enable the door to close.

If this still doesn't work then there is a problem somewhere that needs fixing, probably an adjustment of the lock keeps or the frame. Give us a call if you're still here and need help.

Good luck!
