FAQs

how to fit a double glazed window?

Did you just purchase a double glazed window and confused about how to have it installed? Fitting the window yourself can be quite easy with the help of this step by step guide. However, if you lack proper training or experience, we’d recommend you reach out to a trustworthy professional who can guarantee the best results for help. That said, now let’s take a look at the process.

• Remove the old windows by detaching the old beading and glass window safely. Then make some interval cuts using a hand saw before using a crowbar to pry it out.

• Cut the external double glazed window seal. Once done, take a measurement of the window area’s width once empty. Then transfer the measurement to the window sil to face outside and cut using a handsaw.

• Seal the window sil. Add a bead of clear silicone along both inside lip as well as the centre to seal the sil.

• Screw the double glazed window to the sil. Position the window on the top of the lipped section that was siliconed. Then pre-drill them together and screw in three places. You should make sure the screws do not go totally to the sil’s bottom.

• Install the double glazed window. After successfully screwing the double glazed window to the sil, you can now fit in the double glazing. Make use of packers to make sure it’s even in the slot.

• Screw the uPVC window to the wall. If you’re happy and satisfied with the position of the window, you can then pre-drill through the frame of the window and the brick wall. Once done, simply screw it in place using masonry screws or Spax screw as they do not require crawl plugs in bricks.

• Seal around the window. To do this, simply fill any gaps with expanding foam, wipe out the excess and seal with silicone.

what is a window sash?

Windows, being a very crucial feature in every home, are one of the things you simply can’t afford to ignore in your home. Having a good understanding and solid knowledge of your windows’ components like the window sash will help you stay up to date with them and able to identify any minor mishaps early on before it leads to a much bigger problem. So what exactly is a window sash?

Well without much fuss, a window sash is simply that part of your windows that’s able to open and close. And there could as well be more than one window sash that’s operable depending on your window’s type. Window sash usually possess a very basic design as well as structure. What’s more? This section of a window happens to be a frame that’s designed in such a way to make for easy placement inside the whole window casement. You’ll discover inside the sash frame, the window glass alongside any framework possessed by your window which includes grids.

Usually, the sash is fitted into the frame of the window on a runners’ set in such a way that allows for both upward and downward movements. And finally, the window sash’s frame typically comes with a locking system which provided for extra safety and security.

The window sash is a vital feature that can determine the durability and overall performance of the windows. In the event whereby your window sash is malfunctioning, it can result to numerous problems which includes both drafts as well as leaks. As a result, it’s very important to keep your window sashes in a great working condition as failure to do so will make opening and closing your windows a really difficult task.

Do I need to stay at home while my windows are being replaced?

Most installers will not need you to be at home while they are fitting your windows. It is a good idea to be present though, just in case they have any questions for you and perhaps for your own peace of mind. If you cannot be there, you will need to arrange access to the property and/or agree securing the property at the end of the day.

Will double glazing stop condensation?

If you’ve got a problem with condensation and don’t have double glazing, you should find that getting new windows will help. Condensation is caused by warm air meeting a cold surface which then turns into water droplets. With two panes of glass, less heat will escape from your home and keep the window warmer, meaning when steam from the bathroom or kitchen touches your windows there should be less condensation.
