Sash Windows London

 

 

Sash windows are a classic window style characterised by two vertically sliding sashes within a single frame. They are popular in London for their traditional aesthetic and functionality.

Styles

Sash windows in London typically come in two main styles:

  • Vertical sliding sash: The most common type, where sashes slide up and down.
  • Horizontal sliding sash: Also known as ‘Yorkshire Sash’ windows, where panes slide side to side.
Materials

Sash windows in London are available in various materials, each with its own benefits:

  1. uPVC: The most affordable option, costing between £480 – £1,240 per window. uPVC is low maintenance and energy efficient but lacks the authenticity of timber.
  2. Timber: The traditional choice, priced between £800 – £1,900 per window. Timber offers classic appeal and excellent insulation but requires more maintenance.
  3. Aluminium: A modern option, ranging from £600 – £1,615 per window. Aluminium is durable and sleek but less thermally efficient than other materials.
  4. Composite: Combines wood interior with aluminium exterior, offering durability and classic aesthetics.

Costs

Prices vary based on material, size, and style:

  1. uPVC: £700 – £1,100 per window (including installation)
  2. Timber: £1,100 – £1,900 per window (including installation)
  3. Aluminium: £1,200 – £1,500 per window (including installation)

For a standard 600 x 900mm double-glazed wooden sash window, expect to pay between £360 – £1,485.

Sash Windows Installation costs in London average around £1,200 per window, but this can vary based on factors such as window size and property access

When budgeting, consider that double glazing can reduce energy bills by up to £120 annually. It’s advisable to obtain multiple quotes to ensure competitive pricing.



How does the maintenance requirement differ between uPVC, Aluminium and Timber sash windows in London?



The maintenance requirements for uPVC, aluminium, and timber sash windows differ significantly:

uPVC Sash Windows

  • Require minimal maintenance
  • Need only occasional cleaning with warm soapy water
  • No need for sanding, painting, or staining
  • Oiling twice a year to aid with opening and closing
  • Resistant to rot, corrosion, and pest infestations

Aluminium Sash Windows

  • Require periodic maintenance
  • Need additional care in coastal areas due to salt exposure
  • Cleaning involves removing dirt and grime with mild detergent
  • More durable in extreme weather conditions compared to uPVC

Timber Sash Windows

  • Require regular upkeep and maintenance
  • Need painting or staining every few years to protect against moisture, rot, and insect damage
  • More susceptible to environmental factors like moisture and pests
  • Require sanding, painting, and restoration treatments
  • Prone to splitting and rotting if not properly maintained
  • Overall, uPVC windows are the most low-maintenance option, followed by aluminium, with timber requiring the most frequent and intensive care. However, it’s worth noting that timber windows can last for many years with proper maintenance, while uPVC windows typically need replacing after about 25 years.



Which material offers the best energy efficiency for sash windows in London?

 

Timber appears to offer the best energy efficiency for sash windows. Here’s why:

  1. Timber is a naturally insulating material, providing better thermal efficiency than plastic equivalents.
  2. High-quality timber windows can achieve U-values as low as 1.5 W/m²K when paired with double glazing, competing with modern uPVC alternatives.
  3. Timber frames offer outstanding thermal performance and sustainability. Properly maintained, timber sash windows can last up to 60 years while delivering natural insulation superior to other materials.
  4. While uPVC is often touted as energy-efficient, timber windows are just as effective at keeping homes warm.
  5. Timber’s natural insulating properties minimise heat loss, making it ideal for reducing energy consumption, especially in colder climates.

It’s important to note that the energy efficiency of sash windows depends not only on the frame material but also on other factors such as glazing type, thermal seals, and proper installation. Double glazing with low-E glass, argon gas fills, and quality thermal seals can significantly enhance the energy efficiency of timber sash windows.
