Bespoke Finish

As with all of our products, our uPVC windows are completely tailored to the needs of you and your property. We have a host of options for you, with a variety of colours, finishes, and glazing options. Each window is made individually using your choice of frame and glass.

Highly energy efficient

Our uPVC casement windows are A+ rated as standard and made-to-measure for a perfect fit. The frame and sash have multi-chamber profiles to prevent heat from escaping and low-e internal glass to reflect heat into your home. New Look Double Glazing uPVC casement windows also keep out the cold by filling the gaps between the panes with Argon gas. Then there are the double weather-resistant Q-lon seals to keep out rain and draughts. It’s all this that keeps your home warmer, quieter and helps save you money on energy bills. In addition to this, our multi-chamber uPVC casement window profiles trap air and create a thermal barrier for increasingly better thermal performance. On average, the U-values of our uPVC casement windows are 1.2W/m2K.

Exceptionally secure

With New Look Double Glazing you can rest assured you’re getting windows that meet the British Standard for security, so your home is offered the highest level of protection. We use an internal glazing bead, to prevent the glass from being removed from the outside. Our uPVC windows are also fitted with multi-point locks to ensure your safety.

Practically maintenance-free

Our uPVC windows are built to last and extremely easy to maintain. uPVC is a sturdy material that will never rot, rust, peel or flake and is also lead-free and fully recyclable. They also come fitted with easy to clean hinges, requiring just the sporadic clean using warm, soapy water to keep your windows looking brand new.


uPVC is certainly the long-term solution for your property, with a lengthy lifespan of up to 35 years. uPVC windows do not rot, warp, split or corrode – common problems among other materials.


As a Britain based company, we can understand the importance of weather-proof windows in the damp British weather. We have designed our uPVC casement windows to protect homeowners from any weather-related problems. Our uPVC casement windows will not swell or rot and our coextruded bubble gasket – also known as a compression seal, will ensure that our uPVC casement windows will remain resilient to air and water. This seal is added during the extrusion process meaning the seal is continuous and covers every inch of the window, ensuring that draughts are kept out for longer.

Environmentally friendly

At New Look Double Glazing, we take great pride in serving the planet. We recycle our uPVC and our window frames are completely lead-free, making them environmentally friendly. Our uPVC is also family friendly as it is produced from non-toxic substances including salt. Overall, PVC is one of the most non-toxic, energy efficient, versatile, and cost-effective materials available today.  In terms of recycling, uPVC windows are 100% recyclable and can be recycled up to 10 times, meaning each window has an estimated lifespan of around 350 years. It is for these reasons that uPVC is the most popular material on the market today.
