Further information


From toughened glass and safety glass to hidden hinges and multi-point locks, there are many ways to make your back door more secure. The most important thing is to have good overall burglary protection without leaving obvious external weak points. Even a door as thick as a bank vault wouldn't secure your property if you had unsecured windows.

We recommend an overall security level of at least RC2 for windows and doors leading to the exterior. At this level, breaking your external door takes enough time to make would-be burglars nervous. In many cases, this is enough to scare off burglars as they aren't willing to risk being discovered while working on your door. Make sure not to leave any weak points, such as unsecured glazed surfaces.

High-quality doors

A back entrance door isn't just any door. It's an essential part of your home. And to ensure it's up to the task, it needs a robust frame, well-insulated glass elements, and a reliable multi-point locking system.

That's why our windows24.com doors are produced by experts to the highest quality standards, ensuring all of your new door´s individual parts work together perfectly and that you can get this level of quality at an affordable price.

Online configurator

You can use our online configurator to go through the entire design process step by step. You can mix and match all of the available external and internal options for back doors and front doors, such as:

  • Material (steel and hardwood / uPVC)
  • Type of door (double / single doors / bi-fold etc.)
  • Glazed inserts (type of glass / pattern etc.)
  • Extras like panels (side panels / side lights / fanlights etc.)
  • Opening direction and side of the door handle
  • Colours (from white or anthracite grey to special RAL colours)
  • Measurements and door styles

There are many more options for you to choose from. For example, you can choose which type of external and internal door handle you prefer. Clicking on the question mark symbol will give you information on each aspect of your new door, making your choice much easier. And the best thing is that the configurator lets you preview what your fully customised external door (or internal door) will look like and its price before sale, allowing you to easily keep within your budget.

Government subsidies

With today's increased focus on energy-efficient housing, many local or federal government institutions provide subsidies for well-insulated single or double front doors, installing energy-saving glazing elements and other measures to modernise your home. Check with your county council to see if you qualify for subsidies.

Frequently asked questions

You'll find a wide range of standard measurements on Windows24.com and you can also choose a custom size. Naturally, the ideal size of your back door depends on how much space is available, who will use the back entrance and so on. As a general suggestion, you may not want to make your back door narrower than the front door since the back entrance is typically what you'll use to get the shopping home. Or maybe you'll want to store your bike inside during the cold winter months. Use our online configurator to customise the width and height of your back entrance door.

The price of your new back door depends on many factors, such as the material and which external and internal fittings you choose. Back doors are typically less costly than front doors, and you can further lower the price by choosing a more affordable material (such as uPVC instead of steel with a hardwood / softwood core) or a standard colour (such as white). The most affordable option is probably a single white uPVC patio door without any extras like panels.

While you shouldn't try to lower the price by foregoing security features on exterior doors (such as hidden hinges), you may be able to reduce it by putting less emphasis on thermal insulation. Back doors often lead to rooms which aren't heated. One way or another, you'll want to plan with a low four-digit number when it comes to the projected price of your new back door.

Yes, Windows24.com always provides you with both the leaf and the frame (and any panels you may want). All of these parts must fit together perfectly to provide maximum burglary protection and thermal insulation. So, if you just need a new door leaf for an existing frame, it's best to just order the complete package from Windows24.com and replace the frame as well.

Back doors are often more plain than front doors since they aren't as important to the overall visual aesthetic of your home. After all, you'll probably want to welcome guests through the front door in style, won't you? Thus, back entrances typically don't feature side panels, sidelights, glazed elements or similar extras. In terms of functionality, however, back doors are every bit as intricate as front doors.

The security levels of both doors are typically similar since would-be intruders look for the path of least resistance. All of the exterior security features on your front door may end up being pointless if you skimped on burglary protection for your property and installed non-safety glazed inserts, for example.
