Aluminium Windows
Our thermal break aluminium windows combine slim profiles with superior insulation. Available in sliding, casement, and tilt-and-turn configurations, they achieve U-values down to 1.4W/mK. Bespoke options include dual-colour finishes and integrated security hardware.
Bi-folding Doors
High-performance bi-folding systems with minimal thresholds and seamless corner openings. Load capacity up to 120kg per leaf accommodates extra-large glass panels. Available in 28-57mm glazing thicknesses with multi-point locking systems.
Curtain Walling
Structurally-engineered curtain wall systems for commercial buildings. EW50 series offers three configurations: standard, structural, and linear. Certified to ISTEDIL standards with thermal break technology achieving U-values below 1.8W/mK while maintaining structural integrity.
Glass Balconies
Low-maintenance glass railings with aluminium support systems. Available in in-floor, on-floor, and external models. Compliant with UNI EN 10807 standards, featuring optional top rails and multiple finish options including wood-effect coatings.
Sealed Units
Manufactured on-site using Saint-Gobain glass with 5-10 year anti-misting guarantee. Options include Georgian bars, security-enhanced laminated glass, and argon gas filling. Available in standard and custom shapes with rapid 2-5 day turnaround times.
Questions
Do you supply both standard and custom window sizes?
Yes, we manufacture made-to-measure units alongside standard sizes, with bespoke shapes and dimensions available for architectural projects.
Can existing conservatories be upgraded with your glass roofs?
We provide complete replacement roofs with enhanced thermal performance, transforming traditional polycarbonate structures into energy-efficient living spaces with minimal disruption.
What security features are included in your door systems?
All aluminium doors feature multi-point locking systems, reinforced frames, and optional integrated security sensors. Our composite doors meet PAS 24:2012 standards.
How are large commercial curtain wall installations managed?
We offer full project management including structural calculations, planning submissions, and phased installation to minimise operational disruption for commercial clients.
Are your products energy-efficient?
All systems exceed building regulation requirements, with aluminium windows achieving A+ energy ratings. Thermal break technology and low-E glass coatings optimise year-round temperature control.
What glazing options are available for sound insulation?
We offer acoustic laminated glass with dB reduction ratings up to 40dB, ideal for properties near busy roads or in conservation areas.
