uPVC doors are extremely secure, but composite doors offer the highest level of security. The super-strong structural frame combined with glass-reinforced plastic, provide infallible protection against intruders. Plus, the laminated glass will not fall out of the door if broken. It will shatter but stay in place.

Unlike uPVC doors which are purely plastic, composite doors are made from a number of different materials which are pressed and glued together under high pressure conditions. The materials selected specifically for their properties, and are specifically put together to counteract flaws common in single-material doors.

You may ask ‘What Are Composite Doors Made Of?’ They are much thicker than uPVC doors at 44mm compared to uPVC, which are 28mm. A good quality composite door will be made from the highest quality materials meaning they are strong, durable, secure and weather resistant.

Our double-glazed windows have two sheets of glass with a gap in between, usually about 20mm, while our triple-glazed windows have three sheets of glass, and two gaps. This can make them better at insulating than many double-glazed windows,

The gaps between the glass panes are filled with air, or an inert gas such as argon, to give the best energy efficiency.

Whether you are building an orangery or conservatory, a glass roof lantern or a tiled roof, we’ve got a variety of options to suit both your aesthetic and practical glazing requirements. Whichever you choose, you can expect to benefit from a thermally efficient, highly secure A grade glazing in your new living space. 


Over time your windows and doors or even your conservatory can start to look tired and dulled, everyday living can cause marked and scratched uPVC, and the cost of replacing them can sometimes feel overwhelming and unjustifiable.

Our designers can visit your home and discuss all the options available, so you can choose the best option for you and your home.

Whether you re carrying out planned upgrades and maintenance or it's an emergency repair, Duckworth Windows can help plan and carry out works using only the highest quality materials while causing minimal disruption to your home.

Duckworth Installations only install the very best in double glazing all our windows and doors are made to measure to fit your home.

Our Energy efficient windows come in a range of styles, so you be sure to find the perfect design to suit your home. The energy performance of a window depends on how well these materials stop heat from passing through, as well as how much sunlight travels through the glass and how little air can leak around the window.

Choosing an efficient window
The entire window (the frame and the glass) are assessed to allow for heat loss, draughts, and solar gain, giving a rating that indicates the overall impact of fitting that window in your home. Duckworth’s Windows that have an energy rating and ‘u-value’ of A. A u-value is a measure of how easily heat passes through a material, but it is not a complete measure of how efficient a window is. The overall label rating will give you a better indication of the window’s energy saving potential.

The most energy efficient type of glass for double and triple glazing is low emissivity (low-E) glass. Low-E glass has a microscopically thin coating of metal oxide on one of the internal glass surfaces. This coating reflects heat back into the home but still lets in the light from outside. All Duckworth’s double and triple glazed units use low E glass.
