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 high-tech magnetic tape so it 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.

Quality is at the heart of everything we do. Our team of experienced craftspeople can install CosyGlazing secondary glazing; elegantly seal draughts with concealed brushes and hidden seals; make your lofts and floors cosy with sheep’s wool loft and underfloor insulation; stop the cold spots with sloping ceiling insulation; and restore windows and doors to their former glory.

With our team of craftsmen in Northamptonshire, we work for owners of listed and period properties across the region. Our innovative secondary glazing and insulation solutions are well suited to preserving Northamptonshire’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.
