METALLIC COATINGS

SENDZIMIR system continuous hot-dip galvanized steel (UNI EN 10346), precoated on continuous lines with polyester, high-resistance polyester or PVDF (polyvinylidene fluorides) resin-based cycles, 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 subject to request)
-  Thermal conductivity coefficient λ = 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 as material is more than 95% closed cell
-  Adherence to support surfaces 1 kg/cm²
-  U-value thermal transmittance coefficient in accordance with    EN14509

JOINT

 

The Clack panel joint has been designed to prevent any kind of leakage and has thermal bridges. A continuous gasket is inserted during the production process.

STATIC FEATURES

Clack panels are classed as self-supporting in accordance with that defined in 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.

LATTONEDIL’s technical department is always happy to assist in the event that the designer, based on the climate in the place of installation and the colour of the external support, deems that a detailed investigation is required into stress caused by thermal action and long-term effects.
The designer remains responsible for verifying the fastening system in terms of the number and arrangement of the fastenings.
