Kerb appeal · Serious security
Composite front doors in London, the handshake of the house.
Glazing London supplies and installs composite front doors across London: GRP door slabs on 44mm insulated cores, multipoint locking with anti-snap cylinders, and PAS 24 secure options, fitted by our own installers with a free survey and quote. Composite door installation usually takes half a day. Call 07399 253464, 24/7.
The build
What GRP composite doors actually are
A composite door is a sandwich: a tough GRP (glass reinforced polymer) skin, moulded with a woodgrain or smooth finish, over a 44mm insulated core of high-density foam or laminated timber, hung in a reinforced frame. The skin takes London weather without fading or flaking, the core keeps heat in and boots out, and the whole-door U-value lands around 1.1-1.4 W/m²K, comfortably inside Part L. Compared with the uPVC doors we also fit, a composite slab is heavier, stiffer and holds paint-deep colour better; uPVC wins on budget. We fit both, so you get the honest comparison at survey rather than a pitch.
The gallery
Pick the door the street remembers
Cottage plank
Vertical boarded look with long strap-style hinges optional, right at home on Edwardian semis and anywhere aiming for warmth over gloss.
Contemporary flush
Smooth slab, long bar handle, maybe one slot of obscure glazing; anthracite or black for new builds and modernised frontages.
Half glazed & side panels
Larger glass areas in obscure, patterned or leaded designs, with matching glazed side panels and toplights for dark hallways.
Every design comes in painted, foiled or woodgrain finishes with colour-matched or contrasting frames. If your street sits in a conservation area, check our conservation area glazing guidance first: on protected frontages a four-panel design in a heritage colour is usually the approvable route.
Security first
Built like a secure front door should be
Kerb appeal gets the compliments; the spec sheet does the guarding. A front door takes more attack attempts than any other opening in the house, so we treat security as the default, not the upgrade.
44mm slabSolid insulated core resists kicking, cutting and drilling far better than hollow panelled doors.
MultipointHooks, bolts and rollers lock into the frame at three to five points along the leaf edge.
3-star cylinderAnti-snap, anti-pick, anti-bump euro cylinder rated TS 007 3-star, the part burglars actually attack.
PAS 24Full PAS 24 tested door sets available, with laminated glazing in the slab and side panels, meeting Secured by Design principles.
Fitted rightFrames fixed through reinforcement into brick, keeps adjusted so every locking point engages. A great door badly fitted is a bad door.
From survey to street
Measured, made, fitted in half a day
We laser-measure the opening at a free survey and agree style, colour, glazing and hardware from physical samples. Made-to-order doors typically arrive in 2-3 weeks, fitting takes about half a day, and qualifying installations are registered through FENSA for Building Regulations self-certification, with an insurance-backed guarantee and Simply Business public liability cover behind the work.

And if glass in your existing door breaks tonight, our 24/7 emergency glazing crew will make it safe within hours.
Questions
Composite doors, answered
What is a composite front door made of?
A GRP (glass reinforced polymer) skin over a 44mm insulated core, usually high-density foam or laminated timber, wrapped in a reinforced uPVC or timber subframe. You get the look and heft of painted timber with none of the sanding, swelling or annual repainting.
How secure are composite doors?
Very. The 44mm solid slab resists kicking and cutting far better than a panelled uPVC door, and ours are fitted with multipoint locking and an anti-snap 3-star cylinder. PAS 24 tested door sets, the standard required for new-build and a sensible upgrade anywhere, are available with laminated glazing.
Are composite doors energy efficient?
Yes. The insulated core gives whole-door U-values of roughly 1.1-1.4 W/m²K, comfortably inside Part L requirements, and a properly adjusted multipoint door seals on gaskets at every edge, so draughty hallways usually improve noticeably.
What styles and colours can I choose?
Victorian four-panel with glazing, cottage plank styles, contemporary flush slabs and half-glazed designs, in colours from anthracite and black to heritage greens, reds, blues and woodgrains, with matching or contrasting frames and a full range of chrome, black and gold hardware. Side panels and toplights can be glazed to match.
How long does a composite door take to fit?
Made-to-order doors typically arrive in 2-3 weeks; fitting takes about half a day, and qualifying installations are registered through FENSA for Building Regulations with an insurance-backed guarantee on the workmanship.
