Upgrades to energy-efficient, high-performance windows helps to regulate humidity levels and reduce the risk of condensation forming within the glass panes.

This occurs when the seal breaks down and moisture is able to enter the space between the glass panes. If this is fogging or condensation, it will not only ruin the aesthetics of the window, but can also affect its efficiency and thermal insulation. There are numerous solutions to this problem including drilling and draining the gaps to full replacements, but it's essential that any work is carried out by a licensed tradesperson who is in compliance with Building Regulations Document L, and will provide a warranty of their work. Double-glazed units comprise two glass panes sealed hermetically with a gap in between. This gap is usually filled with argon or air to increase insulation.
