Unrivalled Engineering

Thanks to a cutting-edge multi-chambered structure, our UPVC sliding sash alternatives deliver better thermal performance and energy ratings than their original timber counterparts. Often used in conservation areas due to their authenticity, common issues such as draughts, warping, rotting, and repainting become a distant memory. Whatever the taste or style of your home, our sliding sash windows offer lasting character and designs to suit.



Multi-chambered, ‘A’ rated frames as standard. U-values up to 1.49W⁄m2k. Double or secondary glazing. Excellent weatherproofing.


Safe & Secure

Exceed building regulation standards. 2 locks, 2 tilt knobs, 2 pole eyes & 2 sash lifts as standard. Extra security options available, e.g. limit stops, double-stage keeps and D-handles.


Full Colour Range

Classic woodgrain collection & unlimited RAL colour palette to choose from. Dual colour options.


Made To Measure

Range of extras, including run-through horns, bar designs, cill options & trickle vents. Our surveyors are IQ Level 3 NVQ Certified in Fenestration surveying, so you’re in safe hands with Aim Windows!
