Choosing the ideal double glazed doors for your home is about more than just about aesthetics. It is a smart investment in your Gloucestershire home that enhances its energy efficiency, security, and long term quality. With so many options like double glazed front or back doors, french doors and patio doors on the market, as your local installer, C&L Windows is here to guide you through your options and help you decide with confidence. 

Understanding the Types of Double Glazed Doors

1. Double Glazed Front Doors

Often, the first thing visitors notice about your home is the front door. Double glazed front doors combine curb appeal with performance. At C&L Windows, you can choose between classic uPVC or modern composite styles. Both are reinforced with multi-point locking systems and A-rated insulation to improve the comfort and security of your home. 

2. Double Glazed French Doors

Being timeless and elegant, double glazed French doors feature two hinged leaves that open inwards or outwards. Making them ideal and highly suitable for garden access or connecting indoor living spaces. C&L offers custom colours and finishes to match your home’s character too, so you can decide on which one you like best.

3. Double Glazed Patio Doors

If you want seamless indoor to outdoor living, double glazed patio doors, especially sliding variants, are perfect. They are not only space saving but also crafted for thermal efficiency, thanks to insulated double glazing. With large glass panes, you will also have the best view of your garden and be able to enjoy it even from the comfort of your home. 

4. Double Glazed Back Doors

Back doors often prioritise durability and thermal performance over style. You can choose from robust uPVC or composite options with easy to clean glass, low thresholds, and strong locking mechanisms for busy rear entrances. 

Choosing the Right Glass & Glazing

The performance of double glazed doors depends heavily on the panes and glazing used. C&L consistently installs efficient, A-rated double-glazed units with features such as argon gas fill and warm edge spacers, which reduce heat loss and noise pollution. These measures meet the modern industry standards and are designed to reduce draughts. Making your doors feel extra secure yet easy to open, with the added benefit of a ten-year insurance-backed guarantee on us.

Frame Materials & Energy Efficiency

Frame material significantly impacts performance. For example, when you choose uPVC doors, you should expect excellent thermal performance as they are commonly known for their insulation properties. But also low maintenance and cost effectivity, making them the perfect choice for busy homeowners or those on a tight budget. 

Whereas composite is a door frame material that is the perfect alternative to wooden doors. They are highly durable and give a premium aesthetic appearance, making them ideal for front doors. If you are upgrading from timber or cottage style doors, composite front doors would be the perfect option for you.

Personalisation & Security Features to Prioritise

With C&L Windows, you can make your door uniquely yours. We not only offer a wide selection of materials and styles but also colours.
