About composite doors in Cheltenham
Glass in a door, and in any side panel within 300mm of the door's edge, counts as a critical location when it is within 1500mm of the floor. In England, Approved Document K expects that glass to be safety glass that breaks safely, such as toughened or laminated glass.
In England, if the main entrance door of a home built in 1999 or later has a level threshold, the replacement should keep it level. Making access worse than when the house was built would not comply with the Building Regulations, so the glazier checks the existing threshold and specifies a low-threshold frame where needed.
A composite door slab usually combines a glass-reinforced plastic (GRP) outer skin, moulded with a woodgrain texture, over an insulated core. Some cores are high-density foam, others solid timber. Timber-cored slabs tend to feel heavier and more solid when closed, while foam cores are lighter and insulate well.
Most composite doors use a multi-point lock: one turn of the key throws hooks, rollers or bolts into keeps along the frame. The euro cylinder is the weak point on many older doors, so look for one tested against snapping, such as a TS 007 3-star kitemarked or Sold Secure SS312 Diamond cylinder.

Working in Cheltenham
- Postcodes covered
- GL50, GL51, GL53 and the surrounding area, including Tewkesbury, Gloucester and Stroud
- Coast
- Cheltenham is well inland, around 26 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Cheltenham the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.5 hours of daylight, rising to about 62° and 16.5 hours in midsummer. Dark-coloured doors in direct sun get much hotter than pale ones, so follow the manufacturer's guidance on colour for south and west-facing entrances. Glazed panels and side lights bring daylight into dark hallways, especially on north-facing elevations.
- Access and setting
- Street-facing front doors in towns and cities face more passers-by, so anti-snap cylinders, laminated glass and letterplate guards are worth specifying. Conservation areas may control front door styles and colours, and flat entrance doors onto shared corridors normally need fire-rated doorsets.
- Rules in England
- Approved Document K requires safety glass in critical locations in England: glazing in doors and in side panels within 300 mm of a door, up to 1500 mm above floor level, and any glazing in walls or partitions up to 800 mm above floor level.

Composite Doors in Cheltenham: questions
Can a composite door be fitted with a level threshold?
Yes, composite doors can be supplied with a low aluminium threshold for step-free or near step-free access. In England, where a house built in 1999 or later has a level threshold at the main entrance, the replacement should keep it. Low thresholds need good drainage and some shelter from driving rain, which the glazier checks at survey.
Will a composite door fade or need painting?
Composite doors do not need painting, and the coloured skins are designed to resist fading, although any surface colour can change slightly over many years in strong sun. Clean the door with warm soapy water and a soft cloth, and avoid solvents or abrasive pads. Manufacturer guarantees apply to the finish, and the terms are confirmed in writing.
How much does a composite front door cost?
The cost of a composite door depends on the style, core type, colour, glass, side panels or toplights, hardware and lock specification, plus the condition of the opening. A plain door in a standard colour sits at the lower end, while doors with glazed side panels and premium hardware cost more. See the guide prices; the written quote fixes your price.
Can I change a flat's front door to a composite door?
It depends where the door is. A flat entrance door that opens onto a shared stairwell or corridor is normally a fire door, so only a certified fire-rated doorset is suitable. Leaseholders usually need the freeholder's or managing agent's agreement too. A flat door opening directly outside may be treated like a house door, so check first.
