To improve performance of existing sash windows, secondary glazing can be installed discreetly to the inside of frames, providing an extra layer of insulation that keeps your home warmer in winter and cooler in summer.
In Grade I and Grade II Listed buildings and conservation areas where changes and upgrades to windows are not possible, our bespoke secondary glazing (including slim double glazed units) can reduce heat loss by up to 65% and noise levels by up to 80%. Adding additional windows also slashes a building’s CO2 emissions and enhances security by providing a barrier against unwelcome guests. All whilst preserving the character and charm of your property.
Our secondary glazing units are custom manufactured to your specifications for easy installation and available in the following styles:
All units are designed for easy cleaning and come finished in your choice of over 200 RAL colours.
First class service from sales through to completion. A top quality product, fitted by a highly professional team in an efficient, timely and very tidy process. We would have no hesitation in recommending ERW to friends and family
Mr & Mrs R, Linthorpe
ERW has been a major contributor in improving the physical appearance and energy conservation in our property which sits in the middle of Stokesley’s conservation area. In four phases of design and installation since early 2018 you have helped transform our property with complete distinction.
From assistance given to lodging planning applications with Hambleton District Council through advice on window design and final installation, I can give no higher praise than commending ERW on every aspect of installation.
I first visited your showroom and workshop in the Autumn of 2017 and was impressed with the factory tour afforded me by Kirsty Semark (Customer Service Supervisor). I was convinced that ERW could provide the solution to upgrading our ageing timber windows and appreciate the help and courtesy extended from you and all your staff – many of whom I have met during our four phases of installation.
The very recent installation of a new ‘Eton’ front door enhances the front elevation with perfection.
Please convey our sincere thanks to everyone involved with the workmanship, installation and administration.
Mr U, Stokesley
Having just recently had wooden windows installed by your company, I would like to thank you for the professional and efficient service you provided. From my initial phone call to ERW through quotation and survey it all went very smoothly. I congratulate you on your work force who were all polite, punctual, reliable, tidy, helpful, considerate and very hard working. A CREDIT TO ERW! Needless to say I am delighted with my new windows and would not hesitate to recommend ERW to anyone who wants to deal with a professional family run firm.
Mrs B, Wolviston, Billingham
All staff I met were very professional from office to the 4 installers not forgetting the man who did the survey. I have had lots of compliments from friends and family. Thank you for the attention to detail and the efficiency of the work carried out.
