Parkwood’s market-leading Duramax Composite entry doors are suitable for entrances exposed to extreme weather.
Our composite doors have a 10-year warranty.
Duramax doors have a strong thermal r-rating, thanks to the exceptional heat-and-cold resistant nature of the Polyurethane core, keeping your home warm in winter and cool in summer. The high-impact surface coating can be either a woodgrain or smooth skin finish, ready to be painted or stained any colour although dark colours are not recommended if the door is in direct sunlight.
