German-engineered timber curtain wall systems combining natural warmth, Passivhaus thermal performance, and bespoke configuration for residential and architectural projects.
Glazing Solutions for Grand Design Projects
From double-height atriums to panoramic facades, our curtain walling systems combine structural integrity, thermal insulation, and clean sightlines – available in both aluminium and timber to suit every architectural vision.
What Is Curtain Walling and How Does It Work?
Curtain walling is a non-structural glazing system applied to the exterior of a building facade. Using lightweight materials, curtain wall systems carry their own weight and transfer wind loads and environmental forces to the primary building structure, without contributing to the structural load themselves.
The primary function of curtain walling is to protect the building interior from the elements while maximising natural daylight penetration. Modern curtain wall systems also play a critical role in thermal insulation, reducing heat loss in winter and managing heat gain in summer – making them a key consideration in energy-efficient building design.
Curtain Walling for Residential and Architectural Projects Across the UK
Zyle Fenster supplies premium curtain walling systems for architect-led residential projects, bespoke self-builds, and commercial developments across the UK. Whether you are replacing a solid wall to open up a living space or specifying structural glazing for a high-performance new build, our team provides full technical support from specification through to installation.
Our curtain wall systems are available in two distinct configurations: the Reynaers CW50, a high-performance aluminium curtain wall system, and our Timber Curtain Wall, a wood-aluminium composite system built to Passivhaus thermal performance standards. Both deliver exceptional durability, functionality, and visual appeal – and both can be specified to meet the most demanding energy efficiency requirements.
