Double Glazed Front Doors: Sustainable External Doors (2021 UK Guide)

Become More Sustainable with Double Glazed Front Doors

In 2019, the goal of most home modernisation projects is to improve the house's energy efficiency and eco-friendliness. This has become increasingly important as energy bills have been rising by 28% for thousands of UK homes. Thus, most homeowners are now in search of making their estate more sustainable.

In most cases, the blame is on the external doors and windows, as they are responsible for 25% of the heat loss. By using double glazed doors one can save over three times more heat than having traditional windows. This is why contemporary front doors are built using the double glazing technology.

Similar to double glazed patio doors, modern front doors are durable and low maintenance, and are a lot more secure than regular, non-glazed doors. While it is important that all units are modernised, double glazed front doors are also essential for first-class noise insulation.

Contemporary House with A Double Glazed Front Door

What Are the Differences between Double Glazed Doors and Front Doors?

Double glazed doors can be used for many different situations: internally for separating rooms, as well as for the exterior as front doors, back doors, patio doors, barn doors, and more.

Double glazed entrance doors, however, are much sturdier structure and have usually a remarkably different style than regular doors. Even though traditional doors are often made of simple wood panels, double glazed front doors can be built incorporating many glass elements for a more contemporary design.

Types of Double Glazed Entrance Doors

Double glazed front doors can be purchased ready-made but a number of companies also offers made-to-measure doors. While double glazed front doors can be matched in style with traditional homes, their energy efficiency and security remain state-of-the-art.

What Is the Cost of Double Glazed Front Doors and Frames?

Despite the technology used, it is possible to get access to cheap double glazed front doors starting from £289. Pre-produced doors are accessible at discount prices and are sold in standard sizes that fit many UK homes. In certain shops, free delivery can also be part of the package. Even made-to-measure windows are usually shipped within two weeks.

Cost Breakdown of Double Glazed Front Doors
Type Style Price without installation
Single door Flat panel from £289
Half panel from £299
Full glass from £295
Half panel with lead strip from £339
Victorian, Georgian, Edwardian from £359
Single door with side panel Flat panel from £439
Half panel from £455
Full glass from £449
Half panel with lead strip from £515
Victorian, Georgian, Edwardian from £545
Double door Flat panel from £1,088
Half panel from £1,195
Zinc glazed half panel from £1,256

As a rule of thumb, the custom fitted doors are pricier than ready-made ones. The size of the door is a major influence, too. Front doors can be bought as single doors or double doors. Different styling and accessories add to the complexity which, in fact, increases the prices. Accessories such as letterboxes, door numbers, knockers, spyholes, vents, and more are available as well. Yet, regular units can be fetched for a reasonable price and still increase the energy efficiency, the security, and the value of the house.

Is It Worth Investing in Double Glazed Front Doors?

Equipping your house with modern front doors is a smart investment for a number of reasons:

  1. The increasing household expenditure can be held back by installing a double glazed front door. Double glazing can save £175 per year for a single detached house. For mid terrace houses, savings are still above £100 per year. That means, within a couple of years, the investment is returned.
  2. Double glazed front doors conform the UK energy efficiency standards.
  3. You can reduce your carbon footprint and help the environment.
  4. Having a modern entrance door, your home will be more comfortable as it reduces heat loss and helps to achieve an even temperature throughout the rooms.
  5. Thanks to its heat insulation, the glass on double glazed front doors are less likely to condensate.
  6. Double glazed exterior doors insulate sound better, keeping your home quiet.
  7. Being stronger and being equipped with more advanced locking systems, double glazed front doors are more secure than old doors.

Can Double Glazed Front Doors Have Custom Styles?

Made-to-order front doors enjoy a wide popularity as the custom production allows special requests, such as the size of the glazed element, the size and shape of panel inputs, sculptured design, accessories, lever handles, adjustable hinges, and lead strips, but also the material of the frame, the threshold, and the door, as well as the glaze engraving, the backing glass pattern, and the inside and outside colour of different elements. Technical aspects can also be personalised, such as choosing thermal argon filling between the two sheets of glass for even better thermal properties.

Obviously, heavy customisation affects the end price of the product. Depending on the supplier, you have access to endless combinations of colours, materials, and styles.

Double Glazed Front Door Materials

Despite generally known as uPVC front doors, double glazed front doors can be ordered in several different materials. Depending on the material, different colour or wood pattern can be chosen. Each material has its own design and advantage.

uPVC Double Glazed Front Doors


Simplistic and functional, uPVC suppliers provide a cheap material for double glazed front doors.

Fibreglass Double Glazed Front Door


Similar to uPVC doors, fibreglass offers good protection for a reasonable price. They can even be made to look and feel like real wood.

Wooden Double Glazed Front Door


While more expensive than artificial materials, timber doors offer the ultimate natural look, though at the price of high maintenance requirements.

Aluminium Double Glazed Doors


Metal doors are less popular as they are more prone to thermal conductivity. Their sturdiness and unique look makes them a viable option regardless.

Tips for Additional Security

The preferred material does have a certain influence on the safety of the front door to a limit, though all mentioned materials are considered safe for the regular households living under everyday conditions. There are three main ways to improve the door sturdiness:

  1. Materials: the most durable front door material is galvanised steel. For a cheaper option, uPVC doors can be ordered with a reinforced frame. For a sturdier solution, composite doors may be an option for you.
  2. Safety glass: security glass, that actually looks exactly the same as regular glass, can be used in double glazed front doors while still achieving the same energy efficiency. Different levels of protection can be achieved depending on how toughened the glass is.
  3. Advanced locking systems: there are many accessories available to toughen the lock systems, such as cylinder guard, anti-drill pins in the barrel, and multi-point locking systems.

Double Glazed Front Doors and Frame Colouring

When choosing traditional timber for the entrance door material, numerous natural wood types are available depending on the supplier. Moreover, regular paint can be used to recolour timber doors. Fibreglass and uPVC doors are harder to paint at home, however, manufacturers often offer a vast range of colours, wood imprints, and engraving.

Metal doors are usually painted in the supplying company's paint shop, though some people prefer the raw version due to its contemporary look. However, with clever choices, any material can look fresh and modern. If you opt for the better insulation and cheaper price of uPVC doors, you can give your home a fashionable look by purchasing coloured uPVC windows and doors.

Double Glazed Front Doors with Security Glass

As burglaries are relatively common, it is vital to invest in quality front doors to protect your belongings in your home. In case of a front with large glass units, such as uPVC French doors, the durability of the double glazed front doors becomes even more important.

Security glass can be used for double glazed front doors so well as regular glass. While security glass cost significantly more, producers on the market offer highly toughened glass against crashes, penetration but even against bullets or for resisting explosions.

Reinforced Double Glazed Front Door with Security Glass

How Secure Are Double Glazed Front Doors with Stained Glass?

Traditionally, stained glass doors are considered energy-inefficient and unsafe. This is because of the single layer of protection they offer. Nevertheless, there is a solution for combining the advantages of regular double glazed doors and stained glass. Manufacturers solve this problem by placing a security glass in front of the stained glass element. As a result, the stained glass can be seen from the interior, while the security glass protects the building from break-ins.
