Agate grey flush sash windows

Modern flush sash windows with a heritage look

We recently completed the installation of agate grey PVC flush sash windows at a residential property in Lancaster, giving the home a clean, contemporary finish while retaining a traditional appearance.

Flush sash windows are designed so the opening sash sits perfectly flush within the frame, creating a smooth and elegant look that works beautifully on both period and modern homes.

Project overview

The homeowner wanted to replace older, tired window units with something that would:

• Improve energy efficiency

• Enhance kerb appeal

• Maintain a classic window style

• Require minimal maintenance

• Complement the character of the property

Agate grey was chosen for its subtle, sophisticated tone – a softer alternative to anthracite grey that works perfectly with brick and stone properties common throughout Lancaster.

Why choose flush sash windows?

Flush sash windows offer the charm of traditional timber joinery with the performance benefits of modern PVCu. Key benefits include:

• Authentic flush finish

• Energy-efficient multi-chambered frames

• High-performance double glazing

• Secure multi-point locking systems

• Low maintenance (no sanding or painting required)

• Long-lasting colour finish

These windows are ideal for homeowners who want heritage styling without the upkeep of timber.

Agate grey – a popular contemporary colour

Agate grey has become an increasingly popular choice across the North West. It provides:

• A softer, more refined appearance than darker greys

• Excellent contrast with white interiors

• A modern yet timeless finish

• Strong kerb appeal

The finished installation has transformed the property, giving it a fresh, modern feel while maintaining its traditional character.
