Why Do Conservation Officers Prefer Secondary Glazing?


For owners of listed buildings or those in conservation areas, home improvement isn’t so simple. You face restrictions on what changes you can make to your property, requiring permission from conservation officers before going ahead with work.

Renovation is easier, however, when you know what changes are acceptable and preferred. Read on to see why secondary glazing is more likely to be approved by conservation officers.

The benefits of renovation

As a homeowner, it’s always a good idea to renovate your property. It adds value, as well as improving your quality of life and potentially saving you money over time. But with historical buildings, things like windows, doors and walls – the structure of the building – are protected by law.

It’s a tricky dilemma. You own a beautiful building, soaked in heritage, but you need your local authority to give you the go ahead before you can maintain and improve it. It’s not impossible, though. You just need to understand why they’re protecting the building in the first place.

Protecting heritage

English Heritage, the organisation in charge of listing and conservation, aim to protect the historical interests of buildings. This means stopping any changes that would markedly alter the appearance or structure of the building – what makes it significant.

They also recognise, however, that it’s in the interest of the building to make certain changes. Renovating and refurbishing certain features can avoid deterioration and reduce the vulnerability to vandalism, which would cause more damage to the property.

Essentially what they’re looking for are changes that improve security, strength and longevity without damaging the building’s original features and compromising its heritage. With double glazing, this can be problematic. It requires the original frames and glazing bars to be widened, which has the potential to damage the frames and the authenticity of the windows. Sometimes, it’s simply not possible with the original frames – and will be rejected as a result. Fortunately, there is a solution…

What’s different with secondary glazing?

Secondary glazing is a practical alternative to double glazing that’s ideal for historic buildings. The original windows are left fully intact, with a secondary sheet of glass added to the interior side of your window frame. When renovation is required, secondary glazing is often the preferred option, according to English Heritage.

There are two reasons for this:

• Firstly, it doesn’t damage the heritage of the original window frames.

• Secondly, because it’s a reversible adaptation. There’s no interference with the building’s original fixtures, and the secondary glazing can be removed if needed. Some secondary glazing systems can even be installed to allow quick and easy removal by homeowners themselves.
