A composite door is made from multiple materials to provide excellent strength, insulation, security, and durability.
Xtreme doors offer the look and feel of a timber door without any of the inherent problems, such as cracking, bowing or twisting (or the need to paint them).
They have a high-density foam core which offers excellent strength and thermal performance (very low U-value), and a durable Glass Reinforced Plastic (GRP) skin to protect from the elements. GRP is the same material that is used to make the hull of lifeboats – demonstrating just how tough it really is!
And unlike timber, composite doors are incredibly low-maintenance – an occasional wipe over with a damp cloth will restore it to its original finish.
Woodgrain Finished Options
You can choose to have an authentic woodgrain finish whether you choose white, black or an authentic wood colour. You can also specify white on the inside of your frames and a woodgrain on the outside.
Dual-colour is a popular choice and reflects traditional frames where the outside is painted a different colour to the interior, allowing for greater flexibility in interior decorating.
Below are the Standard and Premium colours available in the Xtreme Door range:
