Secondary Glazing Installation in Balham, South West London

Improving Thermal Comfort and Reducing Heat Loss for Tenants

Invision Secondary Glazing recently completed a residential secondary glazing installation at a property on Marius Road in Balham, South West London.

The property owner contacted our specialist team looking for an effective way to improve the thermal performance of the existing windows and reduce heat loss throughout the property. With tenants living in the accommodation, creating a warmer and more comfortable indoor environment was an important priority.

Our solution was to install professionally fitted, made-to-measure secondary glazing, providing an additional layer of insulation while retaining the property's existing windows.

The Challenge – Reducing Heat Loss Through Existing Windows

Windows can be a significant source of heat loss, particularly in properties with older or less thermally efficient glazing.

For landlords, improving thermal efficiency can help make rental accommodation more comfortable for tenants, particularly during the colder winter months.

At this property in Balham, the objective was to improve heat retention without the need to remove and replace the existing windows.

Secondary glazing offered a practical solution, allowing the property owner to upgrade the thermal performance of the windows while preserving their original appearance.

Our Solution - Made to Measure Secondary Glazing

Our team supplied and installed bespoke secondary glazing designed to work alongside the property's existing windows.

By creating an additional glazed barrier and an insulating air space between the primary and secondary windows, secondary glazing can help reduce heat transfer and minimise cold draughts.

The installation was carried out with careful attention to detail, ensuring the new frames were neatly fitted and integrated with the existing window openings.

In addition to improved thermal insulation, secondary glazing can offer other benefits, including reduced external noise and improved everyday comfort.

The Finished Installation

The completed secondary glazing provides the property with an additional layer of thermal protection, helping to retain warmth and create a more comfortable environment for the tenants.

The discreet design also allows the existing windows to remain in place, making secondary glazing an attractive option for landlords looking to improve their properties without undertaking extensive window replacement work.

At Invision Secondary Glazing, we take pride in delivering high quality installations with precise measurements, professional workmanship and careful finishing.

Every installation is completed by our specialist team, with all secondary glazing backed by our 10-year warranty.
