When to Choose your Windows

Making sure you don’t leave it too late to order windows is really important when you embark on your self build project; and budget especially will always be a key consideration, so it’s always advisable to consider the options as early on as possible so that you're prepared for all costs. Typically your window choices can account for up to 20% of the build cost so it's worth making a decision to suit budget sooner rather than later as you can always then amend your design should budget get out of control. But as a key structural element of the project it’s best to ensure they meet with all your requirements as after all you’ll want then to last as long as possible.

Bespoke windows for specific build projects 

The choice in whether opting for standard off the shelf windows or bespoke windows made will also play a key part in the process as for bespoke you will need to allow for longer delivery periods than with ready-made alternatives. The bonus with bespoke is that your build design will determine the size of the windows, however with off the shelf windows, they will actually determine the build design. Your architect will be able to advise you on what is best for your project.

Energy efficiency - check the U-values

The positioning of the window is also important and in most cases windows will be set 30mm back from the front brickwork, although in aid of thermal efficiency some windows can be installed in line with the wall cavity which will provide greater insulation and improve U-values.

Unusual window styles to retain can still retain excellent U-values

 A U-value, which is the measurement of the rate of heat loss through a material, will impact on the energy ratings of the windows. Legislation states that windows have to comply to a U-value rating of 2.0W/m²K to meet building regulations. Achievable U-values will depend on the size of the window panels, the type of frame, sealants used and also glazing and glazing coatings, so by choosing bespoke windows in particular you could potentially lower the rating and save further on long-term energy bills. So by choosing the right supplier and installer in particular you could potentially lower the rating and make additional savings.

Do I need to replace my windows?


If you’re renovating and not sure whether you need replacements or not keep a look out for the tell tale signs:

• Feeling draft through the window resulting in poor insulation
• If the window sticks or no longer holds open
• If weather stripping is missing or peeling 
• Windows are fogged with condensation there could be a problem with sealant
• Exterior damage such as flaking or crumbling specifically on wooden frames or visible damage through other materials
• External noises are loud within the property

It’s always best however to seek a professional opinion relating to whether the windows can be repaired, but there are wide ranging solutions available to help in the interim until windows can be replaced to help with insulating etc.
