Slim Profile System Curtainwall
A 35 mm pressure-plate and cover-cap system (PB35 Slim Fix), engineered for a minimal exterior sightline.
Minimal expression, engineered retention: the system retains insulated glazing mechanically while keeping the external sightline narrow — a slim 35 mm module expresses the façade grid at every mullion, transom, jamb, head, and sill.
System Reading
- Slim cover cap — 35 mm mullion and transom face expresses the grid.
- Pressure plate — Central fasteners clamp glazing to the carrier profile.
- Insulated glazing — Single or double glazing up to 32 mm thick.
- Thermal separation — Adaptors and gaskets isolate the exterior cap zone.
Performance Envelope
The PB35 platform combines a minimal module with robust glazing capacity.
Design
Feature-cap appearance · Continuous glazing option · Floor-to-floor construction
Application
Single or double glazing · Thermally broken curtain wall · Integration with Technal minimal sliding systems · Tested to ASTM standards
Jamb Detail — Mullion Jamb Section
Section 01 shows the perimeter condition at a reinforced concrete edge.
- 35 mm external module
- 178 mm overall mullion depth
- Steel bracket by others
- Sealant and gaskets form the perimeter air/water seal
- Concrete edge and anchor design to be verified structurally
Typical Mullion Section
Section 02 keeps the same 35 mm exterior expression at an intermediate gridline.
- 35 mm visible cap width
- 178 mm overall depth
- Shared central retention zone
- Continuous internal and external gaskets
- Symmetrical glazing support on both sides
Head and Sill
The 32 mm infill sits within the same 35 mm slim module at both horizontal perimeter conditions.
- Head — Steel bracket by others.
- 178 mm profile depth, pressure plate and exterior cap, seal continuity at concrete soffit.
- Sill — 32 mm glass infill.
- Thermal breaker and gaskets; bent sheet and insulation by others; anchor and bracket coordinated structurally.
Load + Seal Path
The pressure plate transfers clamping force while gaskets and thermal breaks protect the envelope: structural carrier → fastener → pressure plate → gasket → glass.
- Glass — Up to 32 mm infill.
- Gaskets — Continuous compression seals.
- Thermal breaker — Isolates the cap zone.
- Pressure plate — Mechanically clamps glazing.
- Screw — Transfers load to the carrier.
- Capping — Creates the 35 mm face.
Design Basis & Coordination
Use the PB35 limits as a starting point, then verify the complete façade package project by project.
