Condensation on the windows is a common issue for many UK homeowners, specially in homes with single-glazed windows. Apart from being a big inconvenience, condensation may do serious damage to your property, often resulting in mould growth in the home, and it can even infiltrate walls and enter cavities, causing structural damage over time. Not to mention the health risks, as residents of damp or mould buildings are more likely to develop infections, allergic rhinitis and asthma.

At Astral Direct, our double glazing windows are supplied with thermally insulated materials, which assist in maintaining your home and windows at an optimal temperature. These materials are crucial in preventing condensation because they maintain a steady temperature in your windows and home, reducing the likelihood of condensation forming. However, not all condensation is bad, some signs of condensation can indicate that your double glazing windows are working properly, therefore it’s important to identify the type of condensation you have.

What’s Double Glazing?

Double glazing, often known as insulated glazing, is a sophisticated design that consists of two glass panes separated by a layer of air or gas that is inserted. This innovative design creates an excellent insulating barrier, reducing heat exchange between the building’s interior and outside. The sealed space between the glass panes protects against moisture infiltration, making it a potential solution for issues related to condensation. 

Understanding Condensation and how it Occurs

When warm, humid air comes into contact with a cold surface, the moisture condenses and forms droplets. Due to their large surfaces in comparison to the surrounding air, windows are often a good area for condensation to form. The issue is particularly common in single-glazed windows, where the temperature difference between internal and external surfaces is quite significant. 

The Role of Double Glazing in Preventing Condensation

Double glazing can prevent condensation by reducing the temperature difference between the interior and exterior glass surface. The layer between the panes acts as a buffer, reducing heat transfer while keeping the warmth of the inner pane. As a result, the risk of condensation accumulating on the interior of the glass surface decreases dramatically. Furthermore, the sealed airspace within double-glazed units functions as a moisture barrier, preventing warm, humid indoor air from entering the cool external pane and reducing condensation formation. 

The Key Factors Influencing the Efficacy of Double Glazing

Installation Quality

An adequate installation is required in order to improve the performance of double glazing. Any failures or defects in sealing could affect its ability to prevent moisture penetration. At Astral Direct, our experienced installers assure precise installation, ensuring long lasting quality and performance. 

Insulation Properties

The choice of gas filling and airspace thickness between the glass panes have a significant impact on double glazing’s insulating capacities. High quality units with large gaps and low emissivity coatings improve thermal insulation, reducing the risk of condensation. 

Ventilation

Adequate ventilation is vital for maintaining indoor humidity levels. While double glazing reduces condensation, it does not eliminate the need for ventilation. Proper ventilation promotes the elimination of excess moisture, resulting in a healthier indoor environment.

External Influences

External factors such as ambient temperatures and humidity have a substantial impact on condensation. The effectiveness of double glazing in condensation control is determined by the indoor humidity levels and the magnitude of temperature differences between indoor and external environments. Double glazing is a powerful solution for condensation control, taking into account that the installation is executed properly, insulation properties are optimised and ventilation is appropriate and that the external impacts are properly handled.
