Structural
Structural Silicone
Bonds glass to frame in structural glazing walls. High strength, 100% modulus retention, UV stable. 25-year design life with certified adhesion to project substrates.
Facade Sealants & Aluminum Profiles
The materials that make a facade weathertight and thermally efficient. Hanart specifies, tests and supplies structural silicones, weather seals, gaskets and thermal-break aluminum profiles — certified to EN/ISO standards.

Sealants
The right sealant for every joint
Weathering
Weather Sealants
Low-modulus silicone for movement joints, PU and MS polymer for perimeter and transition seals. Color-matched, quick-skinning, toolable in one pass.
Edge Seals
EPDM & Gaskets
Wedge and compression EPDM gaskets edge-seal glass in the frame — extruded to profile, UV and ozone resistant, and compatible with all frame finishes.
Profiles
Aluminum profiles engineered for performance
- Standard extrusions: 6063-T5/T6 mullions, transoms, pressure plates and capping profiles in any sightline
- Thermal break: polyamide/glass-fiber strut profiles achieving frame U-values from 1.2 W/m²·K
- Custom extrusions: die design and production of bespoke sections for unique facade details
- Finishes: anodized (silver, bronze, black), powder-coated (RAL any) and PVDF — with certified coating performance
Why It Matters
Sealant and profile selection decides the facade's life
Water, air and heat move through the joints — not the glass. Correct material selection is the difference between a 25-year facade and a 5-year problem. Hanart tests every sealant-substrate combination before production.
Adhesion Testing
Pull-off adhesion tests on the project's actual glass, coating and frame substrates before production — with documented tensile and elongation data.
Movement Capability
Only high-movement grades (25LM/50LM) used at expansion joints; joint widths calculated from thermal movement, wind and structural deflection.
Compatibility
Sealant-to-gasket, sealant-to-coating and sealant-to-glass compatibility verified in testing — no plasticizer bleed, surface staining or adhesion loss.
Ageing Data
UV ageing, heat ageing and accelerated weathering data supplied for every grade, supporting a documented 20–25 year performance claim.
FAQ
Sealants & profiles questions, answered
Curtain walls use structural silicone (for structural glazing), weather sealants (silicone, PU, MS polymer depending on application), and EPDM gaskets for edge seals. Hanart specifies and tests every sealant for adhesion to the project's specific substrates, coatings and glass.
A thermal break aluminum profile splits the frame section into two halves separated by an insulating polyamide or composite strut, cutting heat flow through the frame. Thermal break frames achieve U-values from 1.2 W/m²·K and reduce interior condensation.
Quality structural silicones are designed for a 20–25 year service life with regular inspection and maintenance. Hanart delivers a sealant maintenance schedule with every project and uses only high-movement-capability grades (25LM/50LM) with certified adhesion.
Yes. Hanart supplies aluminum profiles (standard or custom extrusions) and sealants as OEM/wholesale orders to facade contractors, with material certificates, adhesion test reports and compatibility data.
Adhesion failure is prevented by: (1) pre-production adhesion testing on actual substrates, (2) surface preparation standards (cleaning, priming) enforced on site, (3) qualified applicators supervised by our QA team, and (4) classified adhesion tests per EN ISO 11600/11600. Test results are documented per batch.
