What exactly are Composite Doors?


One of the most frequently asked questions customers ask Hazlemere Windows in our Showrooms is “What exactly are composite doors” and “What is the difference between a composite door and a UPVC door?”

A Composite Door or Windows is any product where the product itself is made up from more than one constituent, therefore by definition “Composite Doors” are products that are made from more than one type of material. So how do plastic doors differ from Composite Doors? UPVC doors are made purely with plastic, namely Un-plasticised Poly Vinyl Chloride, whereas composite doors are made from a number of different materials which are compressed and glued together in high pressure conditions.

UPVC doors tend to only have 28mm deep insulated panels or sealed units, so are not as thick as Composite Door slabs, which are mostly 44mm deep, but can be 48mm or 50mm thick. Composite Doors therefore should in theory offer better insulation, but to what extent will depend on the exact material make up and quality of any particular door. There are many cheap “Composite Front Doors” available on the internet, but just because they have the name “Composite” does not necessary mean they are as good as a high quality UPVC doors, as there are many products made for the mass market to capture those customers who either don’t bother doing any research or who are not bothered about the quality and long term performance, only the look and the price.

Independent double glazing suppliers and installers Hazlemere Windows have over 35 years industry experience, so offer three different high quality Composite Front Door ranges, each of which differs from the other two ranges in terms of composition and construction, but each of which also comes with a robust fully comprehensive 10 year guarantee AND an additional 10 year insurance backed warranty for that extra piece of mind.

The first of these three different ranges is a thick foam filled 44mm door called “Frontline”, with door designs offering a flat wood grain effect looking finish, in over a dozen different door colours and designs. The 2nd range has a slightly thicker UPVC outer skin and a solid wood inner core made up of alternating sheets of ply to ensure reduced movement. These Extreme Solid Core Composite Doors have a 48mm deep door slab and come in a wide choice of colours and designs.  The 3rd range called Ultimate Composite Doors have 50mm thick door slabs with a dense foam filled inner core with an aluminium inner “skeleton” to reduce movement. These Ultimate Composite Doors have a robust UPVC outer skin with a slightly raised wood grain effect finish, and offer dozens of different door designs including several Composite Stable Door Options.

Depending on the range, Composite Doors come with all sorts of different multi-locking systems, various locking barrel security levels, and different levels of thermal efficiency. It is vital to undertake proper research before ordering a composite door to ensure it is not just pleasing to the eye, but also has a decent weather rating that will keep out the wind, rain and draughts, but will also be highly secure and come with at least a 3 star high security locking barrel. The well worn phrase “you only get what you pay for” is so so true when it comes to composite front doors, given the many “replica composite door” products out there that have been made cheaply to be sold cheaply to unsuspecting consumers.
