Double & Triple Glazed Windows

Windows and Doors UK are a UK manufacturer of beautiful, energy efficient, single, double & triple-glazed windows that can be made to fit any residential or commercial property type. Buy your windows directly from us today!

We can supply bespoke windows for single residential applications or commercial applications & premises. Our Window joinery can also supply to builders, house builders & trade suppliers.

Our energy efficient windows are manufactured from premium hardwoods, selected for their quality, durability & sustainability.

Modern timber windows are as robust, hardwearing and energy-efficient as their UPVC counterparts. Thanks to advancements in precision engineering, wooden windows can be made with ultra-fine precision to ensure joints and gaskets form tight seals to maximise heat retention.

Our windows achieve excellent thermal U-Values with minimal heat loss. By trapping air between two layers of glass, double-glazed windows create a barrier that effectively regulates temperature – keeping homes warmer in the winter and cooler in the summer. The space between these layers is usually filled with argon gas, which helps insulate the window and reduce noise.

Window customisation options include sizes available from standard to bespoke sizes, a large selection of premium frame styles & colours, wood stains, paint finishes & ironmongery. Whether you are sourcing new timber windows & doors for your home, or an architect looking for a specific window style for applications, we can assist.

Our articulate manufacturing process involves using premium timbers combined with expert craftsmanship and precision CNC machining to deliver a product of exceptional quality.

Wood treatment technology and insulation mean that our wooden windows are long-lasting, weather, mould and rot-proof (low-level maintenance is required).

We also manufacture and supply a range of timber doors which complement our timber windows.
