TTack

Metallic coatings

Hot dip and galvanized steel, SENDZIMIR system (UNI EN 10346) pre-painted on continuous lines with cycles based on polyester resins, high resistance polyester, PVDF (polyvinylidene fluorides), on the exposed side.
A primer is applied to the underside of the panel.

Insulation
Composed of rigid polyurethane foam that complies with European regulations concerning reaction to fire.
- Composition of polyurethane resin type formula (PUR, PUR B2 or PIR on request)
- Thermal conductivity coefficient 􀁨 = 0.023 W/Mk 
- Average density 40 kg/m³ ± 10%
- Compressive strength 􀀪 0.11 MPa (at 10% deformation)
- Tensile strength 􀀪 0,1 Mpa
- Shear strength 􀀪 0,1 Mpa
- Non-hygroscopic since more than 95% of it features closed cells
- Adherence to support surfaces 1 kg/cm²
- U-value thermal transmittance coefficient in accordance with EN14509

Joint
The TTACK® panel joint is designed to prevent any kind of leakage and thermal bridges. A continuous gasket is inserted during the production process.

Static features
Clack panels are classified as self-supporting in accordance with the definition established by the UNI EN 14509 regulation “… a panel capable of supporting, by virtue of its materials and shape, its own weight and in case of panels fixed to spaced structural supports, all applied loads (snow, wind, air pressure), and transmitting these loads to the supports.”
The loads vary depending on the supports and are defined in LATTONEDIL’s catalogue.The load values refer to panels installed horizontally and subject to a distributed load, without taking into consideration thermal effects, which are verified by the designer.
The creep effect for insulating material, caused by accidental overloads, is taken into account in the static calculation.
