PVC was a happy accident. In the 1800s, two scientists discovered the solid when vinyl chloride gas was exposed to sunlight. PVC was not used in a practical manner until the 1900s. PVC continued to be refined and its uses increased until in 1980s its use of a material for any style of doors and windows were added to a lengthy list. The colours of the PVC doors remain fast and do not fade. They also tend to be less expensive that composite doors which is an added advantage, and are as effective in sealing out the cold air. If you have basic do-it-yourself skills and a few common tools you can install your own pre-hung PVC door.

  3. 3

    Apply silicon sealant to the bottom of the door frame. Fit the frame into the opening.

  4. 4

    Measure in two inches from the ends of the sill and make pencil marks at these points. Drill two holes at these marks. Secure the door with 3-inch wood screws. Apply silicon sealant to the ends of the sill and insert the end caps which are provided with the door.

    Open the door in the frame and fit the frame into the opening. Check the door with a level and insert shims if needed.

    Drill pilot holes in the frame for the wood screws then insert the screws. Make sure you apply silicon sealant to the bottom of the head before securing the screws.
