Slimline Aluminium Patio Doors In Slough & Berkshire

The slimline aluminium patio door is a remarkable innovation that maximises light and minimises the visibility of the frame. If you are looking for a modern-day door solution with a stunning look, look no further than this. These doors are simply a work of art! Thanks to their sophisticated design, they can provide any property with a touch of class and comfort. New Look Double Glazing’s slimline aluminium patio doors are produced from thermally broken aluminium, making them a long-lasting and energy-efficient solution. The thermal break can be found within a gap in between the inside and outside of the door frame and is an effective conductor, not allowing heat to escape whilst ensuring any cold does not enter your property.

An alternative to French doors and bi-fold doors

The brilliance of slimline aluminium patio doors cannot be understated, particularly in smaller living spaces. These sliding doors are unlike the outward opening French doors and the folding bi-folding doors, both of which may interrupt your living space and may require some furniture adjustments. Therefore, if you are hoping for a large opening to your garden with large glass panes for an uninterrupted view of the outdoors without compromising your living space, slimline aluminium patio doors can offer the perfect solution.

Whether you are looking for a replacement internal door or a new patio door for easier access to your outdoor space, our slimline aluminium patio doors offer a perfect solution. You can even personalise the colour and door handles of your slimline aluminium patio door to ensure it does not look out of place in your property. We offer a stunning array of colours and customisations to make your new slimline aluminium patio doors your own. Whichever customisations you choose, these doors will be unique to your property.  The sliding opening mechanism is also effortless to use for all ages and is also noiseless for your convenience.  

Energy efficient

Slimline aluminium doors are the ideal doors to lower your heating bills. The thermal break minimises internal heat loss whilst reducing the amount of external cold coming into your property. By choosing these doors you will significantly reduce your carbon footprint as they minimise energy use. Therefore, whilst being kept warm, you will be helping to protect the environment from climate change.  Patio doors are a perfect match for summer settings, allowing sunlight to beam into your property during the day and the cool summer breeze to steam in during the evening. However, we have designed our patio doors to also withstand the harshest of winter weathers. All our door frames are tightly sealed which prevents draughts from entering your property and keeps the heat in. Our A-rated double glazing is one step we have taken to keep the bad weather out and the heat in. This will effectively help you in saving on your heating bills as well as keeping your property warm during even the coldest winter days. The large panes of glass in patio doors also helps to save on energy bills as a large amount of natural sunlight coming into your property allows you to keep the lights off.


Our aluminium bi-folding doors are not just beautifully designed but are also cost-effective. Their premium look adds a touch of class to any property. These doors offer excellent security and insulation, as well as the versatility of fitting with an array of architectural styles, from Victorian properties to modern apartments.

Noise reduction

We design our slimline aluminium patio doors using advanced contemporary technology. A key benefit of this is the noise reduction in your property. Therefore, if you do not wish for external sound to disturb your peace when relaxing or working at home, our slimline aluminium patio doors are the right choice for you.

Low maintenance

Our slimline aluminium patio doors are easy to maintain thanks to our expert manufacturing. They are powder coated which means they will not need to be repainted and the colour will not fade over time. These doors only require a wipe with a damp cloth to keep them looking good as new.  

Extremely secure

Despite being lightweight and slim our aluminium doors are one of our most secure thanks to the inherently strong material that is aluminium. We further ensure the strength of these doors by using the highest quality aluminium combined with advanced contemporary manufacturing.  We have designed our patio doors with security at the forefront of our minds. All our patio doors are secured with advanced multi-point locks as well as Yale cylinder locks. This lock is resistant to picking, bumping, and drilling and is specially designed to prevent burglaries. These doors are also fitted with an anti-lift device which prevents the door from being lifted out of place. The featured glass has been toughened and is much tougher than standard glass to prevent forced entry. The high-performance double-glazed glass is also useful if you live in heavily noise polluted areas as it keeps out external noise, allowing you a peaceful home.

Environmentally friendly

Here at New Look Double Glazing we take all measures to reduce our environmental impact. Our aluminium is infinitely recyclable, making it one of the most environmentally friendly materials on the planet.
