    Brilliant solution for beautiful, but cold, sash windows.
    Excellent, from the time they sent the sample product and the informative booklet. Ordering was simple and when I queried the delivery date they responded with a personal phone call.
    The secondary glazing arrived as ordered, fits perfectly and we are now so much warmer in our...

    Great product, great service.
    It took us a while to decide to invest in secondary glazing from Extraglaze but we are glad we did!
    From the measuring and fitting instructions to checking details and requirements for accessories and arranging delivery to suit, the service was first class.

    Seems a good product and blends in very well with our decor.
    I had internet quote which was straightforward with good tips and advise on the measuring. Felt confident when I sent it that it would be ok.
    I sent for quote as diy and fitted by extra glaze and my only thought was that their quote for fitting sounded quite high.

    Thank you Lee for the positive feedback. It is true that the labour cost of our Fitted by Us service can be quite high. This is dependent largely on the distance from our nearest fitter and whether the work can be done in one or a series of days that might include overnight stays, etc. Just like we...

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.
