The gap in between the panes is generally filled with an inert gas like argon and sealed securely around the edges with a main and secondary sealant. Inside the spacer bar lies a desiccant (a drying representative) designed to absorb any residual moisture caught throughout production.

Over time, due to age, weathering, or bad installation, these boundary seals can break down. When the seal stops working:

1. Outside air and wetness permeate into the cavity in between the panes.
2. The desiccant eventually becomes saturated and can no longer take in the inbound moisture.
3. When temperature level changes take place, this caught wetness condenses on the interior surface areas of the glass.

This consistent growth and contraction locations tremendous pressure on the window seals. Furthermore, homes exposed to high winds-- common throughout open Hertfordshire fields and raised parts of the city-- may experience sped up wear on window frames and seals.
