Choosing Your Windows

23 Aug

One of the most important things to consider when you decide to replace your old windows is which type of window to choose. There are many different styles of double glazed windows to suit our many styles of property. In this blog post we will just tell you about some of the different types so you can make an informed decision.

  • One type of window is the casement window. These tend to suit larger properties as they are hinged rather like a door and can open inwards or out away from the property. They let in a lot of light and are very versatile.
  • Tilt and Turn windows are another flexible alternative. As the name suggests this type of window can be opened from the side as a traditional window but also from the top. This makes them popular with families as they open more safely but there is still a nice through draught in hot weather. Oh and they also make window cleaning much easier!
  • If you have an older style property you will find the next type of window of great interest. Georgian Bar windows resemble the windows that were seen on Georgian properties. This makes them perfect for older properties making the seamless match with modern technology but still in keeping with the distinctive look of the property.
  • A very traditional style of window is the sash window. These windows open with one or two glazed panels that slide up and down vertically with the use of weights and pulleys. These were very popular in the Georgian and Victorian eras. The original windows were prone to rot and rattling in the wind but with the advent of modern double glazed windows, it is possible to have them installed in your property and still retain the look of traditional sash windows. You can even have them with the weight and pulley system.


Ok let’s look at another factor which needs to be considered in your choice of double glazed windows. What sort of frame do you want your windows to sit in?

Basically there are three types of frame:


  • PVC frames are very popular for a number of reasons. They are usually the lowest cost option, provide good insulation and there is little maintenance required. An added bonus is that the frames are available in different colours including ones that resemble wood grain. They are not the strongest frames and can sometimes be reinforced with galvanised steel when necessary.


  • Timber frames can be very expensive as they are made from varieties of hardwood such as tropical mahoganies and European oak, beech and ash. They provide great insulation as wood is a low thermal conductor. Timber frames give your property a lovely traditional look but do require a high level of maintenance. Bear that in mind if you choose these frames and don’t like DIY!

Aluminium Frame

  • Aluminium frames were very popular when double glazing began to appear in the sixties and seventies. They are very strong and require very little maintenance. They are very long lasting and are particularly suitable for areas in strong sunlight or where there is a lot of wet weather. To improve their insulation a thermal break is incorporated between the frame and the double glazed window. This is insulating material that stops heat being lost from the room to the outside and cold air from entering the room.

    Not sure if I’d agree that Georgian bar windows are a type of window; this is simply a glass option. Good blog, I’ll forward people from my site to here, keep up the good work 🙂

    I rent my house from a private landlord and the local council’s Private Sector Housing dept has had to get involved over some repair and window issues I’ve been having. I have been looking on this site at various blog entries but can’t seem to find anything about size of openings in relation to room size. Is there such a thing in the FENSA regs? If so can someone point me in the right direction? I have 4ft high windows with crappy little openings at the top and want to know if this is “legally allowed” under FENSA regs

      Hi Cindy Thanks for your query which we are looking in to for you.

        With regards to ventilation sizes: Windows must be replaced with openings that are the same size as the ones removed or they can be made smaller if the ones in situ exceed current building regulation minimums. The building regulation minimum for most windows is that the opening must be at least equal to 5% of the floor area of that room. So if the window had an opening greater than 5% of the floor space then it can be made smaller. If the existing window has openings below 5% (for example 3%) then the replacement window would only have to match the current openings size (3%). There are no regulations that say the opening size has to be increased from what is presently available
