Close-up dark sliding doors


Our patio doors always deliver exceptional levels of security, incorporating individual elements to give homeowners ultimate peace of mind. Sliding doors utilise Yale branded four hook bolts, plus two shoot bolts at the top and bottom for enhanced reinforcements. Being such a popular choice for back doors throughout Essex and the rest of the UK, it is vitally important that our sliding doors will be able to provide a significant amount of security. Our high security patio doors are expertly fitted with a number of important features that will keep your home safe. From the multi-point locking systems to the naturally durable uPVC and aluminium materials and reinforced glass, the patio doors here at Double Glazing Essex are designed to keep you and your property secure. You will not have to worry about any break ins with our secure doors at Double Glazing Essex.

Choice of materials

There is a wide range of customisable options here at Double Glazing Essex, featuring a range of colours and finishes that will seriously enhance your back entrance. We offer our customers the choice of having their sliding patio doors engineered in either low maintenance uPVC or sleek and stylish aluminium. Our aluminium sliding doors feature a large array of colour options and narrow yet strong frames. These help to provide some incredible sightlines fit for Essex homes all around the county. Our uPVC sliding doors offer a range of different colours, from Chartwell Green to Irish Oak to Rosewood. Both are equipped to meet the demands of the modern home – albeit with their slight bespoke benefits. Aluminium panels feature slimmer frames to let in more light, for example, while uPVC is durable enough to create complex shapes and stay easy to look after.

Dark sliding door interior


The frames of our sliding patio door styles utilise a uniquely five-chambered design, making them easily some of the most efficient and energy saving patio doors on the market. These additional chambers allow both products to easily trap warmth that would likely otherwise escape from the home. Therefore, the doors will be able to generate A-rated thermal performance as well as naturally causing a reduction in energy bills. After all, one of the best ways to improve thermal efficiency is to ensure that your doors are as energy efficient as possible. These multi-chambered designs help to decrease the U-value of the doors, with the lower the better. The U-value is centred around how effective a door is at keeping heat inside, especially during the winter months. As a result, you will notice your home is kept warmer and those heating bills decreasing.

Frequently Asked Questions

Are sliding patio doors worth it?

Put simply, sliding doors have a higher glass to frame ratio. There is little to obstruct views of your garden or fields behind. Sliding doors may be a better option if your priority is maximum natural light or wider, all-year-round views of your garden.

Can you replace just the sliding door on a patio door?

If the glass panels are the only issue, you may be able to replace them without replacing the frame. However, if the door or frame is damaged or in poor condition, you may need to replace the entire unit. Assess your current sliding glass door situation and take note of any irregularities or damage.
