Sash windows are a timeless choice for homes in Cobham, combining traditional looks with modern performance. Whether you’re renovating a period property or upgrading a more modern home, sash windows can offer style, practicality, and improved energy efficiency.
What is a Sash Window?
A sash window is a type of window that opens by sliding vertically or horizontally. It consists of one or more movable panels, known as sashes, which hold the glass panes in place. Traditional sash windows are usually made from timber and use a system of weights and cords to open and close. Modern versions may use springs and come in materials like uPVC or aluminium.
The design is commonly seen in Georgian, Victorian, and Edwardian houses, but it has also been adapted for use in contemporary homes due to its elegant proportions and ease of use.
Why Choose Sash Windows in Cobham?
Cobham is known for its period properties, character homes, and leafy neighbourhoods. Sash windows fit well with this setting and often meet planning regulations in conservation areas or for listed buildings. Homeowners often choose them for several reasons:
- They preserve the original appearance of older homes.
- They provide good ventilation through the top and bottom sashes.
- They can be upgraded with double glazing and modern seals for energy efficiency.
- They suit both heritage and new-build properties with the right style.
Styles of Sash Windows
There are three main types of sash window mechanisms, each offering slightly different features:
1. Single-Hung Sash Windows
These have one fixed sash (usually the top) and one movable sash (usually the bottom). They are a good choice for homeowners looking for a more affordable sash option, although they offer less flexibility for airflow.
2. Double-Hung Sash Windows
Both sashes move up and down, providing excellent ventilation. Warm air escapes through the top opening while cool air enters through the bottom. This traditional design is common in Georgian and Victorian homes.
3. Sliding or Horizontal Sash Windows
Less common in period properties, horizontal sashes are sometimes used in cottages or modern applications. They open by sliding left or right instead of up and down.
Materials Available for Sash Windows
Sash windows can be made from several materials. Each has its pros and cons depending on the property type and budget.
Timber Sash Windows
Ideal for listed buildings and traditional homes. They offer excellent visual appeal and can be painted to match the property. However, they do require regular maintenance to prevent rot and warping.
uPVC Sash Windows
A popular choice for modern homes or replacement projects due to their low maintenance and cost-effectiveness. uPVC sash windows offer good thermal performance and can be designed to replicate traditional timber.
Aluminium Sash Windows
Slim and strong, aluminium sash windows offer a modern look and maximum light. They are long-lasting and weather-resistant but tend to cost more than uPVC.
Key Benefits of Sash Windows
Sash windows offer a number of advantages, especially when chosen with the right glazing and frame material.
- Aesthetic appeal – Their design suits period homes and adds charm to newer properties.
- Ventilation control – Opening both sashes improves airflow.
- Security features – Modern sash windows come with locking systems and safety stops.
- Energy efficiency – Double glazing and draught-proofing make modern sash windows more efficient than older models.
- Noise reduction – High-quality glazing reduces outdoor noise.
Energy Efficiency in Cobham Homes
Many older sash windows in Cobham still have single glazing, which can lead to heat loss. Replacing them with double-glazed units helps reduce energy bills and carbon footprint. Modern FENSA-certified installers ensure windows meet building regulations for energy performance.
You can also ask your supplier about U-values. A lower U-value indicates better insulation, with modern sash windows achieving values as low as 1.2 W/m²K.
Sash Windows and Planning Permission in Cobham
If your home is in a conservation area or is listed, you may need planning permission to replace windows. Local rules aim to preserve the historic character of Cobham properties. Replacing like-for-like timber sash windows is often acceptable, but switching from timber to uPVC may require approval.
A good sash window supplier in Cobham will understand local planning requirements and can offer advice or assistance with permissions.
Customisation Options
Sash windows can be customised to match your home’s style. Popular options include:
- Glazing bars – Georgian, Victorian, or Edwardian grid layouts.
- Glass options – Clear, frosted, acoustic, or stained.
- Colours – From classic white to grey, black, or timber finishes.
- Ironmongery – Traditional or modern handles and locks in brass, chrome, or black.
Maintenance Considerations
Traditional timber sash windows require ongoing care to prevent deterioration. This includes painting every few years, checking for rot, and replacing seals. uPVC and aluminium sash windows are much lower maintenance—usually needing only occasional cleaning and hardware checks.
Sash Window Prices in Cobham
Prices for sash windows vary depending on material, glazing, and size. Here’s a rough guide for a standard-sized double-glazed sash window:
