Parkwood’s market-leading Duramax Composite entry doors are suitable for entrances exposed to extreme weather.

Our composite doors have a 10-year warranty and the option of wood grain or smooth on most door types.

A thermal r-rating, as a result of their exceptional heat- and cold-resistant filling, helps keep your home warm in winter and cool in summer. The high-impact surface coating can be painted or stained to suit your home and style. Choose either a woodgrain or smooth skin, to be painted or stained any colour although dark colours are not recommended if the door is in direct sunlight. Orientation (Hanging) of Exterior Doors is from the outside of the home.
