Crafted energy-saving secondary glazing and insulation for period homes and listed properties in Northamptonshire.
Mitchell & Dickinson’s CosyGlazing is a unique secondary glazing system that is elegant and effective.
Designed specifically for period homes and listed properties, it is the perfect solution when it comes to insulating the elaborately detailed entrances and bay windows of Northamptonshire’s grand Victorian buildings.
Made of a modern, lightweight equivalent to glass, it’s fixed using magnetic strips so is easy to remove and virtually invisible. Choose a finish to complement your period or listed property.
We also provide high quality draught proofing for period properties such as sheep’s wool insulation.
With the government now announcing Britain will be virtually greenhouse gas free by 2050 and David Attenborough stating that we can all help achieve this goal by insulating our period properties, there is no better time to become part of the solution – and save money on your winter heating bills.
With our team of craftsmen in Warwickshire, we work for owners of listed and period properties across the region. Our innovative secondary glazing and insulation solutions are well suited to preserving Bristol’s celebrated Victorian architecture, fine examples of which can be found in areas of Northampton, Kettering, Corby, Wellingborough, Rushden, Daventry, Brackley, Desborough and Towcester and other areas in this beautiful county.
