What is a Sash Window?
A sash window is a type of window that consists of one or more movable panels, known as sashes, that slide up and down within a frame.
These sashes are typically crafted from wood, although modern variations may incorporate other materials. The defining feature of sash windows is their vertical sliding motion, which allows for easy opening and closing. This design not only provides excellent ventilation but also adds a touch of timeless elegance to any property. Sash windows are renowned for their energy efficiency, as they can be fitted with double glazing to reduce heat loss and improve insulation.
Their aesthetic appeal makes them a popular choice for both period properties and contemporary homes, blending seamlessly with various architectural styles.

Installing double glazed sash windows ensures that your property benefits from energy efficiency without compromising on the visual appeal. These windows are designed to fit seamlessly into existing box sash window frames, preserving the historical look while offering modern performance.
The sliding sash window system remains intact, allowing for smooth operation and easy maintenance, which is ideal for busy homeowners.
Timber Sash Windows: A Sustainable Choice
Opting for timber sash windows is a popular choice for those who value sustainability and durability. These windows are often made from engineered softwood, a material that is both environmentally friendly and long-lasting.
Timber windows offer a natural, warm aesthetic that enhances the look of any home, whether it's a period property or a modern build.
One of the key advantages of timber sash windows is their durability. When properly cared for, these windows can last for decades, making them a worthwhile investment for any homeowner.

Many homeowners today choose wooden sash windows for their unique ability to blend traditional craftsmanship with modern technology.
The counter balance system in wooden sash windows ensures smooth operation, while the use of double glazing enhances energy efficiency. This combination of traditional and modern elements makes wooden sash windows an excellent choice for those looking to maintain the character of their home while improving performance.

Sash Window Hardware and Security
The hardware and security features of sash windows are crucial to their overall performance and functionality.
Traditional sash windows typically utilise a counter balance system, which employs cords, weights, and pulleys to ensure smooth operation of the sashes. This system not only facilitates easy opening and closing but also maintains the balance of the window.
Modern sash windows have taken security to the next level with advanced features such as multi-point locking mechanisms and secure hinges. Additionally, contemporary sash windows may include tilt-and-turn mechanisms and restrictors, providing enhanced security and functionality.
These advancements ensure that sash windows remain a secure and reliable choice for homeowners.

FAQs about Box Sash Windows
What is a box sash window?
A box sash window is a type of traditional window where the sashes, or the sliding parts of the window, move vertically within a frame. The "box" refers to the enclosed area on either side of the window frame where the counterweights are housed, allowing the sashes to move smoothly up and down. This system balances the weight of the sashes using cords, pulleys, and weights.
How to repair box sash windows?
To repair box sash windows, first assess the damage, which may include broken cords, worn weatherstripping, or damaged sashes. Replacing the sash cords is one of the most common repairs and involves removing the window and accessing the weights. You can also improve the window’s insulation by replacing weatherstripping or repairing rotten timber sections. For significant damage, it's often best to contact a professional specializing in sash window restoration.
What is a window sash pack?
A window sash pack refers to a kit that includes all the components needed to replace the movable sashes in an existing window frame. This pack typically includes the sash itself, balance systems, hardware, and sometimes additional materials like weatherstripping. It is designed for homeowners who want to upgrade or repair their existing sash windows without replacing the entire frame.
Is there a cheaper alternative to sash windows?
Yes, a cheaper alternative to traditional sash windows is using uPVC casement windows or mock sash windows, which mimic the appearance of sash windows but operate with a more affordable and less complex system. These alternatives can reduce costs while maintaining a similar aesthetic appeal.
What is the disadvantage of a sash window?
The primary disadvantage of sash windows is that they can require more maintenance than other window types due to their moving parts, including cords, weights, and pulleys. Additionally, older sash windows may not be as energy-efficient unless they are upgraded with double glazing, leading to potential heat loss and higher energy bills.

A mock sash window mimics the appearance of a traditional sash window but does not have the same sliding functionality. Instead, it often opens using a hinge mechanism, making it look like a sash window without the cost and complexity of the traditional sash mechanism.
What is a cottage sash window?
A cottage sash window is a type of sash window where the upper sash is smaller than the lower sash, creating a distinctive asymmetrical appearance. This style is commonly found in traditional cottages and rural homes, adding charm and character to the property.
What is a dummy sash window?
A dummy sash window looks like a traditional sash window but is fixed and does not open. It is often used for aesthetic purposes to maintain the appearance of sash windows in parts of a property where an operable window isn't necessary or desired.

What is an Oriel sash?
