Did You Know Your Sash Windows Were Designed to Keep Your Home Cool?

 Many homeowners don't realise that traditional sash windows were designed to do much more than simply let light into a room. They were also engineered to improve airflow and help keep homes cooler during the summer months.

If your sash windows still open correctly, they can provide an effective form of natural ventilation that has worked for hundreds of years.

How do sash windows cool your home?

Traditional sash windows have a unique design that allows both the top and bottom sash to open independently.

When you open both:

• Cool outside air enters through the bottom sash.
• Warm air naturally rises and escapes through the top sash.

This creates a gentle circulation of fresh air throughout the room, helping reduce heat and stuffiness without using electricity.

It's one of the reasons Georgian and Victorian homes were designed with sash windows long before air conditioning existed.

Make the most of your sash windows this summer

For the best airflow:

• Open the top and bottom sash by around 100–150mm.
• Open windows on opposite sides of your home where possible.
• Ventilate your home during the cooler morning and evening hours.
• Close curtains during the hottest part of the day to reduce solar heat gain.

Used correctly, your sash windows can make your home noticeably more comfortable during warm weather.

Are your sash windows painted shut?

Over the years, many timber sash windows become difficult to open because of layers of paint, worn sash cords, swollen timber or broken weights.

If your windows won't move, you're missing one of the biggest advantages of owning a period property.
