Cleaning the Window Frame

The most effective rubber seal is known as "bubble gasket". This is a round oval or rounded seal, with an arrowhead at one end to aid in keeping it in the grooves of your uPVC frame. Bubble seals are a favorite among homeowners because they're simple to install and keep cold air out while allowing warm air inside.
In addition to the bubble seals, you'll likely have an extra spacer bar inside your double-glazed window, which is used to create an air gap between two panes of glass to provide thermal insulation. The spacer bar contains an emulsifier that's designed to absorb moisture and prevent it from leaking between the two glass panes. But, as with the rest of your double-glazed window the spacer bar is prone to sealant failure, especially when it expands or shrinks with temperature changes.
Applying the New Seal
Apply the new sealant once the area is clean and ready for resealing. Using a caulking gun, press the trigger gently to apply tiny beads of sealant all over the frame. Fill in all crevices and gaps for a secure airtight seal. Use silicone caulk to shield the window frame from water, mould, and other elements. Allow the sealant to dry and cure according to the instructions of the manufacturer prior to returning the window.

In these situations it is recommended to replace the double glazing unit is generally the most cost-effective and efficient alternative than ongoing maintenance work for the windows. Even professional window resealing may not be as effective in dealing with these issues as a full replacement of the double-glazed units.
