Composite front doors in Berkshire: what to know
Replacing a front door usually takes a day on site. The old door and frame are cut out, the new frame is fixed, packed and squared, the slab is hung and adjusted, and the frame is sealed outside and trimmed inside. Plaster around older frames sometimes needs making good afterwards.
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.
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.
In England, replacing a glazed external door is notifiable building work, and whether a mostly solid door counts depends on how much of it is glazed, so the installer confirms what applies. Where notification is needed, an installer registered with a competent person scheme can self-certify the work; otherwise building control approves it.

What applies in Berkshire
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.
Replacing windows and doors with similar ones is usually permitted development for houses in England. Flats, listed buildings and homes in conservation areas or covered by an Article 4 direction can need permission, so check with the council first.
Berkshire is inland, around 56 km from the nearest coast at its closest point, so salt exposure is rarely a factor.
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.

Choosing your composite doors
Solid timber core
A heavier slab with a timber core under the composite skin, giving a solid feel and sound when the door closes.
Colours and dual colour
Woodgrain-textured skins in many colours, often with a different colour inside so the door suits both the street and the hallway.
Hardware finishes
Handles, knockers, letterplates and numerals in chrome, satin, gold, black or graphite, chosen to match the door style.
Insulated foam core
A lighter slab with a high-density foam core, offering good thermal performance and a wide range of styles.
Composite Doors in Berkshire: 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.
What guarantee comes with a composite door?
Manufacturer guarantees apply to the door slab, frame, glass and locking hardware, and the terms are confirmed in writing. Guarantee terms for the installation are set out in writing with your quote, so you know what is covered before you go ahead. Keep the paperwork with your building regulations certificate for when you sell the property.
What glass can I have in a composite door?
Composite door glass comes in sealed cassettes with clear, obscure, bevelled, leaded-effect or decorative designs. Any glass within 1500mm of the floor in a door should be safety glass, and laminated glass adds security because it stays together when struck. Obscure designs give privacy in hallways while still letting daylight in.
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.
