Seals
Seals are an essential component of double glazing because they improve the energy efficiency and insulation of the windows. They are situated between the glass panes of uPVC frames and provide an airtight seal that helps to keep out wind and rain, drafts and condensation which can cause damp on the walls and window sills. Additionally, the window seals help to keep warm air inside and cold air out, which can drastically reduce heating bills.
It's not unusual for the window seals to fail. This is typically due to weathering and exposure to harsh elements like high winds or rain, ice or snow. However, it can be due to improper installation or the use of chemicals, such as paint strippers, which can damage the rubber.
If the window seals fail, it can cause moisture and humidity may seep through the glass panes and cause fogging or misting of windows. Double glazing can lose its insulation properties when the inert gasses between the panes are not present.

Certain manufacturers also produce high-efficiency double glazed units. They use insulated glass and special films to keep the internal temperatures stable, so heating and cooling systems don't have to be as efficient to maintain a comfortable temperature in your home.

If yours is a casement type window, consider installing a Canzak Window Restriction Cable, which works like a chain lock for a door and can be secured to either side of the moving part to stop it from opening too wide. It's also easy to fit and is among the few types of locks that can be used on casements.
A hinged wedge lock could be used to stop the lower sash of sash windows from being lifted enough to allow an intruder to gain access. Cut a strip of wood to match the width of the channel that controls the lower sash, fit it in, and secure it to the frame and wall.
You can also add a sash or casement lock. They are stronger than latch locks, and are often employed together to secure windows. They are found on the side of windows and can be used on double and single hanging windows, as well sliding windows.
