Cords & Weights Sash Windows

Cords & Weights

Traditionally operated with weights and pulleys for smooth and reliable function.

Fixed

Non-opening sash windows designed to maximise light and insulation.

Spring Balance

Operated with a modern spring-loaded mechanism for effortless use. Discover more here.

Our cords & weights sash windows can be customised with an external cill extension and a window board, both tailored to your project’s specific dimensions and requirements.

Single colour

Both sides of the window painted to one choosen colour.

Dual colour

Internal & external sides of the window painted to different colours, including colours from different palettes.

Annealed (Float)

A basic type of glass with a smooth, clear finish and excellent light transmission. It is commonly used for internal applications or secondary glazing where safety is not a primary concern, as it breaks into large, sharp shards when shattered.

Toughened (Tempered/ESG)

A safety glass that is heat-treated to be up to five times stronger than standard glass. It shatters into small, blunt fragments to reduce injury risk. Toughened glass is our standard option for windows and doors, offering excellent durability and impact resistance.

Laminated (VSG)

Formed by bonding two or more panes with a PVB interlayer, laminated glass holds together when broken, preventing shattering. It provides added security, noise reduction, and is ideal for entrance doors or areas requiring enhanced protection.

Argon

The most popular insulating gas for double glazing, ideal for cavities over 8mm. It improves thermal performance by reducing heat transfer compared to air-filled units.

Krypton

Perfect for narrower cavities under 8mm, krypton gas offers better insulation than argon in compact units. Commonly used in slim double glazing or heritage-style windows.

Vacuum

Using a vacuum between glass panes eliminates gas conduction entirely, providing exceptional insulation. Ideal for ultra-slim units where thermal performance is critical.

Fire Rated Glazing (Critical)

Also known as fire-resistant or safety glass, it’s designed to withstand high temperatures and slow the spread of flames and smoke. Commonly used in escape routes, it’s vital for meeting safety regulations in critical areas.

Acoustic Isolation Glazing

Often called soundproof or acoustic control glass, this glazing reduces noise transmission – ideal for homes near traffic or noisy environments. It improves indoor comfort without sacrificing light or thermal efficiency.

Thermal Isolation Glazing

Also referred to as energy-efficient or insulating glass, it reduces heat transfer using advanced coatings, multi-pane setups, and gas fills like argon or krypton – helping lower energy costs and maintain stable indoor temperatures.

Stained Glass

Also known as decorative or coloured glazing, it features textured or tinted panes joined by lead strips to create distinctive designs. Traditionally used in period properties, modern stained glass can be double-glazed offering both visual charm and practical performance.
