Improved Energy Efficiency

Sash windows with secondary glazing provide important advantages in terms of energy efficiency. In the winter, they offer an extra layer of insulation to assist in preventing heat loss and maintaining interior warmth. This may result in cheaper energy costs and cozier living conditions. Due to its ability to reflect heat back into the space, low-emissivity glass can further improve the energy efficiency of secondary glazing sash windows.

Noise Reduction

Secondary glazing sash windows can also help to reduce noise levels in the home. The additional layer of glass helps to block out external noise, such as traffic, aircraft, and other sources of noise pollution. This can lead to a more peaceful and relaxing living environment, particularly for those living in busy urban areas.

Enhanced Security

Secondary glazing sash windows can provide enhanced security for the home. They offer an additional layer of protection against intruders, as they are more difficult to break than single-glazed windows. The use of toughened or laminated glass can further enhance the security of secondary glazing sash windows, as it is more resistant to impact and breakage.

Preservation of Character

Sash windows with secondary glazing can aid in maintaining the personality and history of older buildings. They can be made to match the current windows, preserving the building’s attractive appearance. This is crucial for buildings that are either listed or situated in conservation zones, where the installation of contemporary windows could not be allowed.

Sash windows with secondary glass often provide a number of advantages, such as increased energy efficiency, reduced noise, increased security, and character preservation. For individuals wishing to update their windows without sacrificing performance or style, they are an affordable and useful option.

FAQ’s

What are the advantages of installing secondary glazing on sash windows?

Secondary glazing on sash windows can provide numerous benefits, including improved energy efficiency, noise reduction, and enhanced security. It can also help to preserve the original aesthetic of the property and provide a cost-effective solution for improving the performance of older windows.

Can sash windows be effectively secondary glazed?

Yes, sash windows can be effectively secondary glazed. Secondary glazing can be fitted to both single and double-hung sash windows, providing an effective barrier against noise and heat loss.

What are the U-value requirements for windows?

The U-value is a measure of the rate of heat loss through a window. The Building Regulations in the UK specify that windows should have a U-value of no more than 1.6 W/m²K. However, lower U-values are desirable for improved energy efficiency.

What is the lowest U-value glass available for windows?

The lowest U-value glass available for windows is triple-glazed glass, which can achieve a U-value as low as 0.5 W/m²K. However, this type of glass is more expensive than standard double-glazed glass.

Are A-rated windows the best option for energy efficiency?

A-rated windows are a good option for energy efficiency, but they are not necessarily the best option for every property. Factors such as the orientation of the windows, the size of the property, and the local climate should be taken into account when choosing the most appropriate glazing solution.

Is secondary glazing a cost-effective solution for improving energy efficiency in older properties?

Yes, secondary glazing is a cost-effective solution for improving energy efficiency in older properties. It is often more affordable than replacing windows with new, energy-efficient units and can provide similar levels of performance. Additionally, secondary glazing can help to preserve the original character of the property.
