Secondary Glazing for Listed Buildings

Traditional Joinery Combined with Modern, Heat Efficient Secondary Glazing

Brocklehurst’s bespoke secondary glazing service is an ideal solution for period and listed properties and homes within conservation areas. Where replacement windows are not a viable option, secondary glazing retains heat and reduces noise without damaging the unique aesthetics of the window.

Why Choose Secondary Glazing

Aesthetics

Our bespoke secondary glazing’s unobtrusive design makes use of durable, slimline aluminium frames that accentuate the stylings of the existing window.

Acoustics

Our frames utilise the latest technology to reduce external noise levels by up to 80%

Heat Retention

By tightly blocking draft and creating a barrier of air between the primary and secondary pane, secondary glazing can reduce heat loss by up to 70%.

Why Choose Brocklehurst

We have been restoring and replacing windows in historic buildings for over 30 years working on some of England’s most beautiful period properties.

Completed Secondary Glazing for Listed, Period and Historic Buildings

Take a look through some of our recent secondary glazing projects.

The Muslim Welfare Centre

The Muslim Welfare Centre comprises a Mosque and facilities to support the local Muslim community. As a former Methodist church the building has traditional large, arched windows, 59 in total. Brocklehurst supplied and fitted 59 secondary glazing units, utilising our extensive experience in restoring period windows, to reduce heat loss significantly while retaining the unique appearance of the building.

“One of the things done by Brocklehurst was the supplying and fitting of 59 secondary glazed units as the building did not retain heat and was proving very costly to heat. After the secondary glazing has been installed not only does the building retain heat but we have managed to save a considerable amount on our energy bills. I would like to thank Duncan, John T, Joe, John M, Mark, and the whole team for the exceptional work that they have carried out on our premises.”

Eccles House Farm

This stone farmhouse dates from 1814 and contains 8 windows of varying sizes, some set in stone surrounds and others with period wooden lintels. Brocklehurst supplied 8 bespoke windows allowing as much light to enter the room as possible whilst keeping as much heat as possible trapped inside the building.
