*We have installed Extraglaze Secondary Glazing magnetic secondary glazing in all types of listed buildings, in conservation areas and in World Heritage sites. In every case, after discussion with the relevant bodies, no formalities/consent was required. We advise that customers always make appropriate enquiries in case an exception should arise, however usually a phone enquiry is all it takes to get clarification. Should you need information to send to your Conservation Officer please call or email with your request: we can send diagrams for this purpose. Please also order a Free Sample.


**In tests conducted for us at Coventry University, Extraglaze Secondary Glazing suffered 78% less condensation than the aluminium framed glass secondary glazing, when fitted to a sash window, with high humidity 'indoors' and temperatures of between -5 and -10 centigrade 'outdoors'.


***In tests conducted for us at the Building Research Establishment, we compared Extraglaze Secondary Glazing against an aluminium system stiffened by sliding framework running down the centre of the window. This stiffness gave it a slight advantage. Whereas the Extraglaze Secondary Glazing had no stiffeners, and looked much better for it. Had we stiffened it we believe they would have been more comparable.

 

Fitting Service - or DIY

We can expertly install for you or supply fully assembled panels for you to fit with our full guidance. Order your free sample pack here.

Solutions for listed buildings & conservation areas

Extraglaze Secondary Glazing is the ideal secondary glazing solution for Listed Buildings and for those in Conservation Areas, being particularly suitable for buildings of historic significance. Planning Permission or Listed Building Consent will almost certainly not be required from your local authority. "most authorities encourage the fitting of secondary glazing to increase the thermal efficiency of period windows."

Fitted by Us service – for a fuss free installation

We provide a complete Supply and Fit service, from the initial survey right through to fitting and after sales care. You can get an initial estimate online here without the need for our surveyors to call. If you are happy with your online estimate you can book a comprehensive survey comprising a site visit and fixed price quotation.

Alternatively, to conveniently obtain an initial, informed estimate please send us your own approximate measurements and large, good quality photos of your windows in the first instance.

Where do we install?

van medWe are constantly expanding our network of installers. Some will, and frequently do, travel anywhere they are required to go. Use our Fitter Finder tool to find an installer near you. Most installers will come to you for free within a 50km radius, except for inner city areas where congestion impacts on travel time. If you are beyond a reasonable distance, we will ask a fair and reasonable charge for travel time and fuel.

DIY - fully assembled for you to install

We supply DIY secondary glazing panels ready to install. These are not kits, they are made to measure, fully assembled and ready to apply. In many cases all you need to do is open the box and fit the panels to your windows. We will supply a comprehensive set of fitting instructions and are available to offer help via our helpline phone number or via Skype or Facetime. Download our measuring guide here and then enter your measurements into our online estimator where you can also place an order.

Extraglaze in Telford, formerly in Shrewsbury, is both a supplier and installer of specialist secondary glazing services, with a rapidly expanding network of trained fitters. Our customers include home owners, offices, schools, even holiday resorts with single glazed windows. We frequently install our secondary glazing in listed buildings and conservation areas, as well as church conversions, often with arched and stone framed windows. Extraglaze will even turn double glazing into triple glazing, and stop condensation. If you live in a noisy city or town centre, especially with draughty, badly sealed sash windows, it will bring you the sound insulation you never imagined possible, even as you watch the traffic pass by! We insulate sash windows and insulate casement windows. All our panels are made to measure. We make special shapes, arches and out-of-square panels, even bowed (3 dimensional) panels for windows that follow curved facades. We supply and fit magnetic secondary glazing for sash windows and casement windows, and of course stained glass windows. If you require energy saving windows then insulating sash windows is a great alternative to window replacement or window renovation. The low cost of secondary double glazing is affordable compared to replacement sash windows & replacement casement windows. Extraglaze offers window thermal insulation and sound insulation for existing windows including stained glass windows. Both double glazed sash windows and triple glazed sash windows are possible. Extraglaze can turn draughty old windows into energy efficient windows. We have Fitters in Newark, Grantham & Nottingham, also in Newcastle upon Tyne in the North East. Installations are taking place in Hove, Lewes & Brighton. Additionally in Central London: Islington and around Mile End. We have installers in Weymouth and Swanage, Dorset.

Important advice


Monday 5th August 2024


Currently new orders will be dispatched within 3 weeks.

Great summer news! Many customers say Extraglaze is keeping their homes cooler in the summer. So, yet another benefit, and another energy saving if you have air conditioning.

DIY customers: please order a Free Sample and Measuring Guide, and spend time in our FAQs. You may get your answers immediately, instead of waiting for a reply from us.

Want to have Extraglaze installed by one of our fitters? Please request our services well in advance of the winter period - after that time we may be fully booked up, but don't hestitate to ask, because we are steadily increasing the number of fitters available throughout the UK. Please consider, if you know a good trades person locally then they could be your best first-point-of-call. We want to support them, rather than disappoint you altogether. For their benefit please order a Free Sample and Measuring Guide in advance. When your windows prove challenging we can work with them to survey your windows from photos and approximate dimensions, or a video conversation. If you need the expertise of a Master Fitter we will make this clear.
