Why uPVC for doors here
Unplasticized polyvinyl chloride is rigid, weather-resistant and dimensionally stable. Against the two materials it usually replaces:
Against timber. It does not absorb moisture, so it does not swell in monsoon and shrink afterwards — the cycle that opens joints and jams doors. No termites, and no repainting.
Against mild steel. It does not rust. In salt-laden coastal air, a painted steel door frame starts corroding at the fixings and cut edges within a few years, and once rust is under the paint it spreads.
It also insulates. uPVC conducts far less heat than aluminium, so the door is not bringing the afternoon sun into the hallway with it, and the multi-chambered section damps sound better than a hollow metal one.
What separates a good one from a cheap one
Steel reinforcement
uPVC profiles are hollow. Over a door-sized leaf they rely on galvanised steel inside the chambers to carry the weight and resist the daily thermal cycle. A door is heavier than a window sash and used far more often, so this matters more, not less.
Omitted or undersized reinforcement shows up as a leaf that bows, drops on its hinges, or stops closing cleanly after a couple of summers. It is invisible at purchase, which is why it is worth asking about explicitly.
Locking
Modern door security is in the lock, not the leaf. A multi-point system throws hooks or bolts at several points up the frame, spreading any forced load rather than concentrating it at a single deadbolt.
It does a second job as well: those locking points are what pull the leaf onto its gaskets, so the same mechanism that secures the door is what makes it weather-tight.
Glass
Any glazed panel in a door should be laminated, because it is at body height and a break would leave an opening. See glass options.
Styles we make
Entrance doors — solid or part-glazed, with the emphasis on security and weather sealing.
Patio and balcony doors — sliding where floor space is tight, lift-and-slide where the panel is large or the opening exposed.
Casement French pairs — where you want the full width to clear and have the swing space.
Finishes
White, solid colours and woodgrain foils, and the inside face does not have to match the outside. Because the colour is in the foil rather than a paint film, there is nothing to maintain. See colour options.
Made in Bhandup West
We fabricate our own uPVC systems, so reinforcement and hardware specification are our decisions rather than inherited from a supplier, and non-standard openings are made to size. See how we manufacture and door installation for how they are fitted.
