How much does a double-glazed front door cost?

Can you double glaze a front door?
Yes, it is possible to double-glaze a front door. Our team can assess your front door and discuss the options available to enhance its energy-saving performance. Composite doors are also extremely popular nowadays for front doors, and these also provide exceptional security and insulation properties.

What is the difference between UPVC and composite doors?
UPVC doors are made from unplasticized polyvinyl chloride, offering durability and affordability. Composite doors, on the other hand, are constructed from a combination of materials, including uPVC, timber, and insulating foam, providing superior strength, security, and thermal efficiency compared to UPVC doors.
 

What is the lifespan of a composite door?
Composite doors are known for their exceptional durability and longevity. With proper maintenance and care, a high-quality composite door can last upwards of 25 years or more, making it a long-term investment in the security and aesthetics of your home.

Will a composite door make my home warmer?
Yes, composite doors are designed to enhance the thermal efficiency of your home. With their insulating properties and tight seals, composite doors help prevent heat loss and drafts, keeping your home warmer and more comfortable throughout the year.

What type of front door is most secure?

Composite doors are considered one of the most secure options due to their multi-layered construction of wood, uPVC, and a reinforced frame. They also come with multi-point locking systems for enhanced protection. To maximise security, look for these features: multi-point locking systems, toughened or laminated glass panels, reinforced frames and security hinges.
