Why Composite Doors Stand Out

According to Ultion, it takes just 9 seconds to snap standard cylinder locks and enter a home. That’s why we supply and fit composite front doors secured with an Ultion 3-star cylinder lock. Approved by the Master Locksmiths Association, they hold the Sold Secure Diamond mark, the highest security grade for locks available.

FAQ

Composite door questions, answered.

Composite doors are made from a selection of different materials which can include timber, uPVC, glass-reinforced plastic (GRP), foam insulation and a thermoplastic polymer skin. The combination of materials makes a composite door one of the strongest on the market.
Composite front doors can add value to your home. They have attractive designs to give a great first impression for the entrance to your home. Improving how your home looks from the street can make it more appealing to potential buyers. Even a new door colour can impact value. They also provide increased energy efficiency, security, and longevity benefits.
uPVC doors and composite doors are different because of the materials used to make them. uPVC doors contain insulation and are made of a uPVC outer layer. Composite doors are made of a mix of wood and insulating materials that are sealed in with an outer layer that is usually made of glass-reinforced plastic (GRP). Composite front doors are considered stronger than uPVC doors as a result.
As composite doors are made from layers of materials, they can provide better sound insulation than single-layered, thinner doors. But their ability to reduce outside noise depends on the quality of the composite door. This includes things like the thickness, design of the door and the quality of installation.
Composite doors come in a range of prices, the cost reflecting things like the dimensions, design, and any extras like colour or door furniture. To get an accurate quote for your home, get in touch with our team today.
While it is possible to paint a composite door, you shouldn’t ever need to. Composite doors are built to last, with any colour built directly into the material, making it resistant to fading. If you do want to paint a composite door, make sure to choose a paint specifically designed for composite materials.
Composite doors can be installed into almost any frame, but to achieve proper security, reliability, and energy efficiency, a composite door should be installed along with the matching frame it was designed for.
Condensation is something that can happen in any home, created when warm, moist air comes into contact with a cold surface. Composite doors help to retain warmth and are designed to be very durable in any weather, but condensation can still happen if it’s cold outside and warm indoors.

We provide a complete range of professional double glazing doors & windows. From new installations to repairs and maintenance.
