Frequently Asked Questions

What is a vertical sliding window?

A vertical sliding window uses two sash panels that move up and down to open. It is designed to preserve traditional sash proportions while integrating modern frame technology and glazing performance.

Are vertical sliding windows suitable for conservation areas?

They can be, depending on local authority requirements. Heritage-style detailing such as sash horns, glazing bars and period-aware colour choices can help satisfy design expectations, but approvals vary by property and location.

Can I get modern security standards with sash-style windows?

Yes. Vertical sliders can be specified with modern locking hardware, and standards-led options such as PAS 24 and Secured by Design upgrades can be reviewed during survey where needed.

Do vertical sliding windows improve energy efficiency?

Compared with aging or poorly sealed units, modern vertical sliding systems with current glazing and perimeter seals can reduce heat loss and support more stable indoor comfort.

Do vertical sash windows tilt in for cleaning?

Selected systems include tilt-in functionality and restrictor options, which can make upper-storey cleaning safer and more practical from inside the home.
