Condensation - The Facts



The Problem

Condensation on windows and in conservatories, and the damage it does to paintwork, curtains, wall coverings and window fittings, are problems frequently encountered in all types of building.

What is condensation?

Condensation is the water which results from the conversion of water vapour in the atmosphere.

How double glazing helps

Double glazing is an insulator, designed to reduce the loss of heat by conduction from the inside to the outside of a building.

The location of condensationon the glass

When attempting to reduce the degree of condensation it is important to note on which surface of the glass it forms; its location indicates the cause, and so points to the solution.

Summary

Condensation is a ventilation problem and cannot be caused purely by the installation of double glazing. By acting as a heat barrier and providing an inner pane which is considerably warmer than the outer pane, condensation may be reduced.
