Key Features
Advanced Thermal Efficiency
Behind the clean, contemporary exterior lies our innovative Thermlock® multi-chamber technology. This sophisticated thermal design provides exceptional insulation against harsh British weather conditions.
The specialised insulating chambers function as an effective thermal barrier, working together with high-performance glazing to deliver industry-leading thermal retention that significantly outperforms traditional polyamide thermal breaks.
Balanced Aesthetics
Our Prestige bi-fold doors effectively dissolve the boundary between indoor and outdoor spaces, creating a seamless transition that enhances your home’s sense of openness. When fully opened, these doors allow you to embrace your garden as an extension of your living area.
Our uniquely engineered single roller system eliminates the need for floating mullions, ensuring consistent 138mm sightlines between door panels. This careful attention to detail creates our signature balanced aesthetic across all door styles.
Comprehensive Security
Every aluminium bi-fold door is built with security as a priority, featuring robust 5-point locking mechanisms and double deadbolts throughout the design. For additional protection, we incorporate full-length security interlocks on appropriate configurations, which firmly secure the door panels together against attempted forced entry.
Sophisticated 'Thunderbolt' Locking
Our passive door options include an integrated finger pull lock, removing the requirement for a secondary handle and maintaining the clean, minimalist appearance. An innovative mishandling prevention feature ensures doors are secured in the proper sequence. This premium locking system provides exceptional security without compromising on aesthetics, giving you complete peace of mind while maintaining the sleek, architectural lines of your bi-fold doors.
