Retrofit double glazing - winter story

  • A warmer house in winter comes from using Low E double glazing as it helps to keep the heat in your home, meaning less need for heating systems, so you’ll be reducing energy consumption, which saves on your power bills.

  • During winter, homes with single glazing can lose significant heat through the windows. retrofitting these with new Low E double glazing can make a huge difference to the comfort levels of your home. The glass you choose will make a difference to the comfort of your home and the size of your energy bills.

  • If thermal insulation and keeping your home warm is important to you we have a Low E solution that can help reduce heat loss through your glass by up to 79%*. Resulting in a warmer home, and reducing the likelihood of condensation, mould and mildew.

Retrofit double galzing - Summer story

  • A lot of sunshine can start overheating your home especially if you have large east - or west - facing windows.

  • Think about your location/climate and the orientation of your home, this will help you decide how much solar control do you need.

  • Solar control is when you can limit or control the amount of excess sun's heat from building up inside your home during the hot summer months.

  • We have a range of solar control option glass types that you can combine in your double glazing to help reduce the excess heat. These glass types are ideal for windows and doors exposed to a lot of sunshine.

Retrofit double glazing - aluminium joinery

  • Our retrofit double glazing systems are compatible with most aluminium joinery systems, it is rare for us to come across a home that we can’t retrofit. 

  • Our retrofit aluminium process involves removing the single glazing out of your window. We change the glazing bead that holds the single glazing in place with a new bead to accommodate the new double glazing unit, without changing the window frame.

  • There is a subtle change in the surround of your sash windows and we upgrade hinges and stays for the heaver double glazing. Sliding doors may need adapters depending on the age of the system but are also easily upgraded.

Retrofit double glazing - wooden joinery

  • We would recommend keeping your timber frames unless there is severe rot on the outer frame where you may need new replacement windows.

  • Our dry glaze RetroFit system uses new timber beads to hold the new double glazing, with the system having a better performance than traditional putty or wet glazing such as silicone. You should also consider getting draft seals as sometimes timber windows have gaps that do not close fully, which will help prevent unwanted excess airflow in and out.

  • Timber is an excellent insulating material which is why we recommend retrofitting it. This also allows you to maintain the character of your home and gives you the thermal performance of double glazing.
