COMPOSITE DOORS

COMPOSITE DOORSComposite doors are those which are made of more than one material.Composite doors have been designed taking into consideration the common flaws.Composite doors have now become the preferred choice of entrance doors for many people due to the major advantages that composite doors have over the alternative wooden doors, steel doors and UPVC doors.Super strong, high security, easy maintenance, excellent thermal efficiency, a lifespan of at least 35 years and the general look andfeel of a composite door make it the most popular door choice on the market.Both sides of the door has a 2.5mm grp (glass reinforced plastic) outerskin that requires very little maintenance

Benefits

• 44mm thick extra strong door leaf• excellent thermal performance• low maintenance• coloured through 2.5mm grp outerskin• realistic woodgrain appearance• wind and water resistant• no warping, twisting, cracking or bowing• choice of door and frame colours• safe and secure• 35 year lifespan

Are composite doors energy efficient??

U value rating of 1.8W/m2K or less

Use of calcium zinc waste compound in the extrusion of door frame (is much kinder to the planet than lead based additives).

The inner polyurethane foam system is 100 percent CFC free and is thermally insulating.

•Composite doors are made up from a variety of materials, including PVC, wood, insulating foam and GRP (glass reinforced plastic). •The combination of materials result in a door that is very strong and secure.•Composite back and front doors have a high resistance to weathering and will not react to seasonal changes like a singular material door.•The core of a composite door can contain wood,insulating materials and many other layers which are all protected by a weather resistant outer skin.•A composite door is designed to appear as a wooden door, with an attractive wood grain, but thanks to the materials used, it won't fade, discolour or require any maintenance beyond wiping with a damp cloth if it gets dirty.•In short, composite doors are exceptionally well-designed modern doors made from several materials. Their superior quality sets a new high•standard within the door industry.

Comparison of Wooden and UPVC DoorsUPVC Wooden

Highly weather resistant and less maintainence

Requires continuous maintenance and not weather resistant

Thinner and have less strength

Thicker and strong,thus safer

Composite doors is the one which rectifies the flaws of both these types of single material door.The main thing to understand about composite doors are that they are made from multiple materials which ensures great strength,durability and looks.
