Business Details
We established Heka Windows Group in 1994, beginning with uPVC Schco and Rehau windows before expanding into aluminium systems. Our expertise now spans aluminium, timber, steel, and composite windows, utilising world-leading systems like Schco, Panoramah, Reyners, and Sunflex. We serve architects and planners across the UK, Germany, USA, and beyond, delivering bespoke solutions with distinctive design qualities. Our products meet stringent UK and EU certification standards, including Certass, and come with a 10-year guaranteed warranty. We specialise in high-performance fenestration, combining thermal efficiency, security, and aesthetic appeal.
Our timber windows achieve passive house U-values, while steel frames offer ultra-sleek elegance for maximum glass area. Aluminium systems provide up to 98% glazing coverage, and our seamless sliding designs maximise luminosity. Composite windows merge external aluminium durability with internal timber warmth for minimal maintenance. We take pride in our ability to support global projects with tailored, certified solutions. Our decades of experience ensure we meet the highest industry standards. We remain committed to innovation, sustainability, and client satisfaction in every project we undertake.
