Sliding Sash Windows
Traditional sliding sash windows combining period charm with modern uPVC technology and energy efficiency.
CONTEMPORARY WINDOW SOLUTIONSOur flush casement windows create a sleek, contemporary appearance where the openable parts sit perfectly flush with the outer frame. Unlike regular casement windows that have a protruding lip, this modern flush casement design delivers clean lines and sophisticated aesthetics. We install both uPVC options from the renowned Residence Collection and premium Sheerline aluminium windows to suit every home.
Having enjoyed a surge in popularity over the past decade, flush casement windows offer a contemporary alternative to standard casement windows, with the sash sitting perfectly level with the outer frame. This creates clean, uninterrupted lines that really boost any property’s appearance.
The flush sash design provides excellent weather sealing and improved security compared to traditional designs. You’ll enjoy impressive thermal efficiency, reduced maintenance, and a modern aesthetic that adds real value to your home.
Choose from an extensive palette including classic whites, contemporary anthracite, and authentic timber finishes like Irish Oak and Silvered Oak. Our dual-colour options let you match your interior décor whilst creating the perfect external impression.
Our flush casement windows achieve excellent thermal performance with U-values as low as 1.0 W/m²K with triple glazing and 1.4 W/m²K with double glazing. This translates to lower energy bills, and a more comfortable home environment. Security features include:
Our uPVC flush casement windows come from the prestigious Residence Collection, featuring advanced multi-chamber designs and authentic timber aesthetics, with the low maintenance benefits of uPVC. The R7 and R9 systems offer seven and nine-chamber profiles respectively, delivering exceptional thermal performance and durability.
For those preferring aluminium windows, we use Sheerline systems with slim profiles and superior strength. The slim frames that aluminium is renowned for allows larger glass panes to be fitted, leading to a higher amount of natural light in the home. Aluminium is also incredibly secure, long-lasting, and durable.
