Winterproofing Series: Windows

This week in our Winterproofing Series, we are looking at windows and exploring ways in which we can improve energy efficiency in older homes. This week’s blog is a long one so credit to you if you stick it out until the end!

Windows are an essential part of any building, providing natural light, ventilation, and views to the outside world. In historic buildings, windows are often not only functional but also beautiful works of art that reflect the architectural style of the period.

There are many different types and styles of windows in historic buildings, each with their own unique characteristics. To understand the most appropriate ways to improve energy efficiency, the type and style of window must first be identified to determine the most appropriate course of action.

Types of Windows

Some of the most common types of windows include:

Styles of Windows

Architectural styles have evolved over time, and windows have reflected these changes, taking on distinct characteristics that define different eras and styles.

Medieval: these windows were typically small and narrow, reflecting the limitations of construction techniques at the time. They were often decorated with stained glass.
Tudor: Tudor windows were characterised by their rectangular shape and often featured diamond-shaped panes, creating a distinctive pattern. They were commonly used in Tudor-style homes.
Georgian: these windows were known for their symmetry and proportion, reflecting the classical ideals of the Georgian era. They were typically large and sash-style, providing ample natural light.
Victorian: Victorian windows were characterised by their elaborate designs and varied styles, including bay windows, oriel windows, and sash windows with decorative embellishments. They reflected the Victorian era's love for ornamentation.
Queen Anne: Queen Anne windows were often bay windows or sash windows with intricate detailing, such as stained glass, geometric patterns, and decorative mouldings. They reflected the Queen Anne style's emphasis on asymmetry.
Art Deco: Art Deco windows were characterised by their geometric shapes, bold lines, and sleek forms, reflecting the Art Deco style's emphasis on modernity and geometric abstraction. They were often used in public buildings and commercial structures.

Window Materials

The materials used to design these windows depended on the period in history and availability of resources.

Wood was the most common material used for windows in historic buildings, especially in medieval and Tudor-style buildings. Wood is a strong and durable material that can be easily carved and shaped. It was also relatively inexpensive and readily available.
Stone was also a common material used for windows in historic buildings, especially in medieval and Tudor-style buildings. Stone is a strong and durable material that can withstand the elements. It was also a status symbol, as only wealthy people could afford to have stone windows.
Lead was used to hold the panes of glass together in windows. Lead is a soft and malleable material that can be easily shaped. It was also a good sealant, which helped to prevent drafts and leaks.
Glass was a luxury material in historic buildings, as it was expensive and difficult to produce. Early glass was often flawed and uneven, but it became clearer and more refined over time.
Stained glass was used to decorate windows in churches and other important buildings. Stained glass is made by adding metal oxides to glass, which creates a variety of colours.
Iron was used for window frames in historic buildings, especially in Georgian and Victorian-style buildings. Iron is a strong and durable material that can withstand the elements. It was also a relatively inexpensive material.
Steel was also used for window frames in historic buildings, especially in Art Deco-style buildings. Steel is a strong and durable material that can withstand the elements. It was also a relatively inexpensive material.
Aluminium was used for window frames in historic buildings, especially in mid-century modern-style buildings. Aluminium is a light and strong material that is resistant to corrosion. It was also a relatively inexpensive material.
In the late 20th century, PVCu was introduced as a material used for constructing window frames. PVCu is a strong and durable material that is resistant to corrosion. It was also a relatively inexpensive material. However, its use in historic buildings is not recommended as the visual character and operational differences are unsuitable for the character of the building. In addition, the components used to manufacture PVCu windows result in them being weaker than timber which means they are made thicker. There is also a common misconception around the service life of PVCu, their life expectancy being less than 25 years, compared to well-maintained traditional windows which can survive for upwards of 100 years.

Identify Draughts

Draughts are common in all buildings, regardless of age. Once areas of draughts are identified within windows, there are a few options to consider:

Weatherstripping: this is a flexible seal that can be applied to the gaps between the window sash and the frame. It helps to block draughts and prevent air from leaking out of your home.
V-stripping: a type of weatherstripping that is specifically designed for gaps between the sash and the frame. It is a good option for older windows that have larger gaps.
Draught excluders: these are long, thin strips of material that can be placed along the bottom of windows to block draughts. They are a simple and effective way to improve window insulation.

Repairs and Thermal Upgrading

Once initial draught proofing has been undertaken, if you wish to further increase the thermal efficiency of your windows, it is advised to first do a basic recording including photos and basic measurements before undertaking repairs.

When repairing window joinery, always rectify the source of the problem first - such as where damp is getting in. If you need to apply preservative treatments, these can be brushed onto the affected area after the decayed wood has been cut out.

The following are localised repair suggestions taken from Historic England’s guidance ‘Traditional Windows Their Care, Repair and Upgrading’:

Loose joints should be re-secured by cramping, gluing, re-wedging and pinning.
Decayed joints should be taken apart and defective members repaired by piecing-in.
New wood and as much of the existing as possible should be treated with a solvent-borne preservative before fitting.
Metal angle-repair plates, let in flush, may be used as a temporary repair to the corners of sashes.
New timber cills should be made of durable hardwood, such as oak, thoroughly primed and painted and where appropriate incorporating a drip.
Spliced repairs should be made by cutting out rotten wood and splicing or scarfing-in timber inserts which are shaped to obtain the maximum strength and to match the existing profiles. The new timber should always be worked to the line of the existing and should follow any existing deformations in the line of the window.

Where the window is to be painted, small areas of loss can often be made good with fillers based on wood dust mixed with a two-part epoxy resin or polyester resin. The worst decay is first cut away, but not back to sound wood; instead, weakened areas are strengthened with a resin consolidant. Removed material is then replaced with a filler or a combination of filler and timber.

Final Thoughts

When it comes to maintaining energy efficiency, understand your building first and always repair before considering replacement, particularly within historic buildings. This is usually a much cheaper option and retains the significance of the building, if done right.

Maintenance work, such as redecorating and repair of windows will not generally require consent for listed buildings or buildings in conservation areas.

If you are uncomfortable repairing windows yourself, consider hiring a professional window contractor.
