Composite Door Life Expectancy

Our solid cottage style composite door set achieves a `U` Value of 1.0 and an energy rating of A, while our half glazed Composite door achieves a 'U' Value of 1.4 - great numbers for keeping the digits on your energy bills low. The warm edge spacer bar technology in many of the double glazed units are even more efficient. It gives the composite doors a better overall energy rating compared to other UK composite doors available. Lower energy bills and better for the environment. Our GRP composite doors give you a nice warm feeling - all year round.

Take a look at how well our composite doors perform compared to the rest of the market. (Information from HAPM (Housing Association Provident Mutual) and BRE (Building Research Establishment)).

  • Colour match door drips
  • The door drip is the strip that runs across the face of the composite door at the bottom, it deflects running water from the bottom of the door. Drips have been made to match the colour of your door so it doesn’t stand out, not a silver or gold bar found on alternative composite doors. * Colour coded door drips not available with bespoke RAL colours.

  • Colours
  • Composite doors are available in 13 standard external door colours; black, red, green, blue, white, oak, darkwood, chartwell green, cream, grey, duck egg blue, black brown and poppy red. RAL, Farrow & Ball and BS colours are available upon request. As standard, the internal door is white grained.

    The solid colours are pre-pigmented which means the colour is added during the manufacturing process. As the skins are applied, the colour goes on evenly. The oak and darkwood finish is a hand-applied stained finish to give depth to the woodgrain.

    All composite doors have a high gloss, UV resistant film to give them a final sheen.

  • PVC edge banded doors
  • We've looked at every detail of our GRP composite doors, and edge banding is no different. The edge of the composite door is finished using an ash grained PVC. Once the edge has been applied, it is then trimmed and the edges milled to a radius so there are no sharp corners.

  • GRP Skin
  • Every composite door boasts a Glass Reinforced Plastic (GRP) woodgrain skin as standard.

  • High security locking system as standard
  • The composite doors are fitted with a PAS24 Secured by Design Police Approved multipoint hook lock and a high security anti-snap cylinder as standard.

  • Dedicated low threshold
  • The composite door has a dedicated design for the low threshold specifically for the door and is Part M compliant. It has concealed face drainage and a thermal break.

  • Dedicated top box transom
  • Adding a top box is simple with our composite doors. Because the frame has a dedicated transom bar, it is made in one piece. This makes it extra strong and looks good.

    The glass pattern will match the glass pattern chosen for the main glass design. So if you've ordered Crystal Diamond on Stippolyte, the top box can also be in Stippolyte.

  • Fully suited hardware
  • The composite door has fully suited hardware so whether you choose gold, chrome, black, graphite or white hardware to finish your door, you can be sure of a perfect match. Everything from knockers and numbers to handles and hinges are designed as a complete suite. Gold finishes often tarnish, but with the hardex gold finish the gold has been toughened to withstand even the harshest elements.

  • PAS23, PAS24 & Kitemark
  • Our composite doors are being tested to the highest levels. All ready to install composite doors will conform to PAS23 and PAS24 as standard. These doors will also carry the annexe D accreditation that tests the continued operability of the door after a simulated aging process. The new TDS standard, with the gusting test, have also been included.

    Please note unglazed composite doors carry no certification.

  • Composite Doors with Side Panels
  • Side panels use the same composite door frame for a perfect colour match. They are available glazed or with a matching composite side panel.

    Glazed panels are internally glazed and unless specified will automatically come with the same glass pattern as the main door, so if you ordered the Cottage Half Glazed Composite Door with Cotswold glass, the glass pattern in the side panel would also be Cotswold. Glazed panels can also be fitted with the unique transom section.

    All GRP composite front door and side panels are fastened to the composite door frame using heavy duty 20mm aluminium coupling sections and then clad in PVC.
