Interweaving modern-day facilities and comfort with the traditional features of historic properties is one of the major challenges faced by architects and builders renovating period houses. Creating a characterful property that caters effortlessly to the needs of 21st century homeowners is something that takes careful planning and, very often, ingenuity. 

Sourcing the right materials and expertise is crucial to any build project, but when the care and conservation of historic architecture is involved, this becomes even more critical. Windows in particular can create difficulties when listings prohibit replacement or alteration.

Secondary glazing is an ideal solution. By creating an internal window, on the inside of the original window, you can have all benefits in terms of reducing thermal and noise pollution, but without compromising the integrity of your original windows since the glazing is not visible from the outside of the building.

It is vital that you choose a company with specific experience in working with period homes. Storm Bespoke Secondary Glazing is a recognised supplier to heritage buildings, from private period homeowners to organisations such as English Heritage, the National Trust, Historic Scotland and Cadw.

Effectively draught proof

One of the most common challenges with original windows is draughts. These are caused when there is a gap between the window and frame causing cold air to enter the house and warm air to leave. Regardless of severity, it is vital that windows are effectively draught-proofed to improve the insulation of the home. The severity of the problem dictates the appropriate response. Some draught-proofing can even be done on a DIY basis. Use foam, metal or plastic draught strips, or brush seals for sash windows, available from any DIY store. Alternatively, employing a professional will still be a fraction of the cost of a replacement.

Find sympathetic window replacements

When it comes to original features you should always try to repair rather than replace. Even if your windows may look irreparable, having succumbed to rot and broken glass, you’d be surprised at the restoration that can be achieved. If you do need to replace the windows find a company who are used to working on Listed Buildings.
