Insulated Doors


Standard and fire-rated hinged, sliding and roller doors for all situations.

P. H. Insulations supplies and installs a variety of standard and fire-rated insulated doors, from single personnel doors to roller shutter doors. Our range includes:

  • Hinged single personnel doors
  • Emergency exit doors
  • Double doors
  • Double action ‘crash’ doors
  • Manually operated large sliding doors
  • Electrically operated large sliding doors
  • Insulated partition doors
  • High speed doors
  • Roller-shutter doors

Single and double personnel doors are available in standard and bespoke sizes as hinged doors or sliding doors, with core materials offering fire ratings of up to 4 hours. They can be supplied primed ready for painting on site, or finished in any colour to suit project requirements. Single and double personnel doors are manufactured from either anodised aluminium or stainless steel, with fully welded corners, available with a food-safe finish to the door and doorframe. Other options include kick panels and vision panels – necessary if a door opens up into a corridor for example.

Standard core materials for insulated doors that are not required to be fire rated include polystyrene and polyurethane. Fire retardant door cores vary according to the required specification, including PIR (polyisocyanurate), which offers a fire rating of up to 1 hour, and mineral fibre – which offers a fire rating of up to 4 hours.

We have an extensive manufacturing and storage facility, with CNC machinery for manufacturing bespoke components, supported by a range of standard materials in stock. This allows us to provide an efficient response to many requirements, including insulated doors in bespoke sizes made to individual specifications.
