Secure Composite Door

One of the key benefits of our composite doors is their advanced security features. We prioritise  the safety of your property and loved ones, which is why our doors are equipped with advanced multipoint locking technology. Our composite doors also feature a 48mm thick timber core which acts as a sturdy barrier to entering your home, they are also coated with a aluminium coating that acts as a protective layer to your door. Choose a door that can withstand strong forces and harsh weather conditions. All of our glazing within our composite doors is double glazed which is almost impossible to break so no point of your door can be exploited. This ensures that your home is protected against unwanted intruders, giving you peace of mind. Here at DL Windows, you can trust that your property is secure.
