TECHNAL TENTAL Visible Grid Aspect
TENTAL Visible Grid Curtain Walling
Dortech Architectural Systems Ltd designs, manufactures and installs TECHNAL TENTAL visible grid curtain walling systems for commercial and public sector projects across the UK. TECHNAL extrudes the aluminium system profiles, and Dortech transforms those 6 metre aluminium extrusions into project-specific façade packages through design, fabrication and installation.

TECHNAL TENTAL Visible Grid Aspect
TECHNAL TENTAL is a modern aluminium curtain wall system designed to combine architectural creativity, transparency, thermal performance and sustainability.
TECHNAL extrudes the aluminium curtain walling profiles into 6 metre bars. Dortech then designs the project-specific façade, manufactures the system in our UK factory and installs the completed curtain walling package on site.
This relationship between TECHNAL system design and Dortech project delivery allows architects and contractors to benefit from a recognised aluminium façade platform, supported by specialist fabrication and installation expertise.
Feature Caps & Bead Glazing
TENTAL visible grid aspect includes two key aesthetic routes: Feature Caps and Bead Glazing.
Feature CapsProvide a bold, structured visible grid appearance with customisable cap designs.
Bead GlazingCreates a refined framed look and a contemporary alternative to traditional pressure plate and cap detailing.
Architectural FlexibilityAllows designers to create clean, modern façades with controlled sightlines and strong visual rhythm.
Design Performance
TENTAL is designed around sleek 50mm and 60mm profiles, supporting transparency, thermal efficiency and contemporary façade design.
Feature Caps support faceted façades up to ±20°, while Bead Glazing supports faceted façades up to +10°, giving architects flexibility when developing shaped, angled or expressive building envelopes.
The system can accommodate large glass panels and integrates concealed opening solutions for ventilation, helping retain a clean external appearance while supporting practical building use.
Weather Performance
TECHNAL publishes strong weather performance values for TENTAL 50 and TENTAL 60 visible grid configurations, supporting long-term façade performance across demanding commercial projects.
Air PermeabilityBead Glazing: AE 1200 Pa. Feature Caps: up to AE 1500 Pa for TENTAL 50 and AE 1200 Pa for TENTAL 60.
Water TightnessBead Glazing and Feature Caps: RE 1500 Pa configurations published by TECHNAL.
Wind ResistanceService 2000 Pa and Security 3000 Pa for TENTAL 50 and TENTAL 60 configurations.
Glazing CapabilityFeature Caps support glazing from 6mm to 62mm. Bead Glazing supports large glass panels from 28mm to 44mm.
Carbon-Conscious Façade Design
TENTAL is positioned by TECHNAL as a carbon-conscious façade system, integrating at least 75% recycled content and being 95% recyclable.
TECHNAL also references Hydro CIRCAL aluminium, which contains at least 75% end-of-life aluminium and achieves a CO2 footprint of 1.9 kg CO2e/kg of aluminium.
For clients, contractors and design teams focused on sustainability, this means the curtain walling specification can support wider environmental goals while still delivering architectural quality and technical performance.
Dortech’s Role
Dortech does not extrude the aluminium system profiles. TECHNAL extrudes the aluminium into 6 metre bars, and Dortech uses those system profiles to deliver the façade package.
Our role is to provide the specialist design coordination, manufacture, fabrication and installation required to convert the TECHNAL TENTAL system into a completed curtain walling installation on your project.
With more than 20 years of experience working with TECHNAL systems, Dortech is well placed to support architects, main contractors and developers with visible grid curtain walling packages across the UK.
