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
