The loss of seal could also be caused by environmental factors, such as exposure to direct sunlight or by the use of chemical cleaners which can damage the glass and cause damage to the seal.
When a seal fails it can create a snoring sensation in a home and it is not unusual to notice an increase in the energy efficiency of a home as a result. It is important to perform a visual inspection of your double-glazing regularly.

When replacing a double-glazed sealed unit, it is essential to measure the proper size of the existing window. This is because the UPVC frames they sit in are not tolerant of movement, and if a new unit is too big it will not fit. To make sure that this is done correctly it is crucial to remove the beads and measure them. This will ensure that the new sealed unit is of the correct size.

Depending on the design of the window, it may be required to prime or paint the window prior to applying the sealant. It's important that any paint or varnish is allowed to dry completely before the sealant is applied.

Position the blade on the edge of the bead, and then gently pull it away from the frame. To avoid damaging the window frame, make several shallow cuts instead of one deep cut. Once you have removed your bead frame, gently lift it away from the glass pane that remains and set aside.
Shave any remaining sealant off the bottom of your glass with an instrument or knife. replacement window gaskets will ensure a strong bond when the glass is re-sealed in the future. When the glass is clean thoroughly clean both sides of it to remove any residues or smears.

If you choose double-glazed units that are a few millimeters bigger than the original the frame will not seal properly. To avoid this issue make sure you measure the width and height of the window you have previously installed and relay the measurements to the supplier.
A double-glazed unit's seal can break down for a number of reasons however the most common is the result of condensation between two panes of glass. This can cause unattractive calcium deposit or a draught on the glass. This is a sign of an issue with the sealed unit's gas filler or moisture that has entered the frame.
