    Cannot recommend highly enough - superb service and standard
    First class - I made a mistake on my measuring and Nic and his team could not have been more accommodating. Glazing is now in place and looks superb. The white border on both glazing and inner magnet (ensuring it still looks discreet in summer when the glazing is removed) is very good...

    Product : We fitted one window first to see how they were. Reasonable simple to install for 70 year olds. Brilliant product which looked amazing and prevented the condensation (mostly) straight away. there is still some...
    This condensation is a good sign, that the wooden frames are drying out - moisture is perspiring from it! This is a great result for your precious window frames. You can take the panels off to wipe down the windows (while the moisture is condensed on the outside glass), but don't do this early in the...

    Excellent product.
    Very helpful on the phone. 2 week turnaround. Really good product.
    Product : We have fitted 8 windows so far. They look amazing, almost invisible. Condensation immediately disappeared on 5 windows with just a small amount on the other 3. I think this is due to damp windows which...

Examples of bespoke Extraglaze solutions for listed buildings

While we'd love to say that we have developed our product for English Heritage, or for the Institute of Historic Building Conservation (IHBC), we actually develop Extraglaze for each and every client, just whenever we are asked to. And, as we do this, nothing does us more proud than receiving some approving looks or blatant praise from a local Conservation Officer. Quite simply we take great enjoyment from solving your secondary glazing challenges!

On this page you will read about just a few of those that presented themselves in listed buildings. In each case we developed several ideas, in our heads, on paper or with prototypes before agreeing with the customer exactly how to proceed, and ultimately solved difficult problems. In at least three of the examples here a Conservation Officer was party to discussions before work started, and vetted the end result – to the delight of our clients!

Example 1: A client with a 16th Century Farmhouse with original timber mullioned windows on the northern side with glazing (identified in an English Heritage book) commissioned Extraglaze to provide magnetic secondary glazing. A magnetic panel was developed to disappear into a distorted oak frame, with a draft excluder on the bottom edge to avoid adding an additional room facing surface along the sill. We also developed panels with two new choices of oak effect vinyl edge sourced exclusively for this client.


Example 2: A client with a Grade 2 Listed black and white half timbered detached house built in 1580. This commission was particularly challenging since some of the windows were dramatically trapezoid. For this building a magnetic panel was developed to disappear into the distorted oak frame using a veneer instead of vinyl. Sliding panels were also developed incorporating magnets which were a new and bespoke development peculiar to this building.


Example 3: A client with a Regency listed building with original panel single pane sash windows and a first floor door to a balcony. Extraglaze worked with the local Conservation Officer and gained approval for secondary glazing which took into account the distortions to all windows, ensuring maximum sound and heat insulation. The glazing was developed specially for this building and offered a higher level of sound proofing than a standard Extraglaze installation.


Example 4: A client with an apartment in a grade 2 listed converted Victorian coach house with three large wood framed windows. Extraglaze developed a magnetic panel to work around an extractor fan and still be invisible. As the panels to be installed were very large and exposed to the full force of the summer sunshine for prolonged periods, Extraglaze, through various trials, also changed their adhesive and developed their installation methods to solve problems that presented themselves on this job.
