    Replacement double glazed front and back doors in Kent

    As standard, all of our front and back doors will be fitted with our high-performance double glazing. When combined with our high-quality door materials, they provide the thermal performances you’d expect of a replacement door from a leading double-glazing installer.

    Our double glazing is fabricated with two panes of dense glass that encompass a section of argon gas. Through this multi-layered approach, it retains the warmth inside and keeps the draughts from entering, so you can even save money on your heating bills. Another benefit of our double glazing is its superior noise reduction abilities, guaranteeing a comfortable atmosphere inside your home.

    Innovative comfort glass front and back doors

    comfort glass is becoming more common across the UK thanks to its unparalleled performance. It’s a great solution for properties in busier areas as its layered design eliminates any external noises from entering the property. Comfort glass can be incorporated into both front and back doors.

    Our comfort glass is manufactured with an additional laminated layer, meaning it provides even greater temperature control. 365 days of the year, the cold will be kept out and the heat kept inside. It achieves excellent energy ratings and U-values.

    Toughened glass and laminated glass to add extra security

    Our back-door styles that include large panes of glass are fitted with toughened glass, which is also referred to as tempered glass. It’s a popular security glass option as it is five times stronger than standard glass. Its highly effective durability will significantly reduce the likelihood of an unwanted intruder gaining entry. When impacted, it will shatter into hundreds of miniscule pieces, so reducing the occurrence of injury.

    Laminated glass boast an inventive manufacturing process that combines the two panes of glass into one, considerably increasing its strength and ability to stay undamaged when smashed. This is an ideal glass option for families with children and pets as it will stay intact until it is replaced, and pieces of glass won’t cause harm.
