Reinforced PVC is not only for windows. It is also used for entrance doors, back doors and some interior doors exposed to moisture. Here is what to know before choosing.
PVC front doors
Strengths
- Insulation: multi-chamber profiles and an insulated panel give good thermal performance for a moderate budget.
- Low maintenance: PVC needs no painting and copes with rain and salt air.
- Price: usually the most affordable option compared with timber and aluminium.
Limits
- Stiffness: on large sizes, proper steel reinforcement is essential to stop the leaf from warping.
- Dark colours: facing south, they heat up and can expand; manufacturers offer dedicated ranges for this.
- Style: entry-level models can look less premium; decorative panels and wood-effect foils narrow the gap.
Buying criteria
Multi-point lock, protected cylinder, insulated threshold, double seals and the lowest possible Ud value (the door equivalent of Uw).
Interior and utility doors
- Utility room, garage, shower room: PVC is fully moisture-resistant, where unprotected timber would swell.
- Garage-to-house door: an insulated door stops a cold garage from chilling the adjoining rooms.
- Living areas: timber or hollow-core doors remain more common for their decorative look, but PVC excels in technical spaces.
PVC, timber or aluminium?
- PVC: best insulation-to-price ratio with minimal maintenance.
- Aluminium: stiffer and slimmer, ideal for large contemporary doors, provided it has a thermal break.
- Timber: warm and insulating, but the finish needs regular upkeep.
In practice
For a PVC front door, ask for the data sheet: maximum permitted size, reinforcement section, AEV rating, Ud value and lock security level. These figures let you compare quotes objectively.
