Our flagship high efficiency platform

Steel Core uPVC is designed around slim, symmetrical European profiles that maximize daylight while delivering strong insulation and tightness. The system is built on a technology platform focused on stiffness, security, and long term performance, including bonding inside, foam inside, safetec inside, and powerdur inside. Optional glazing bonding increases sash stiffness and burglary resistance, while multi seal options support improved air and water tightness and comfort.

• Modern symmetrical design that fits contemporary architecture 
• Narrow profiles for more glass area and natural light 
• Advanced technology options that improve stiffness, security, and insulation 
• Double seal or triple seal configurations for comfort focused builds
