TTACK®

The world’s only panel for flat roofs

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 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 TTACK® panel joint has been designed to prevent any kind of infiltration and thermal bridges.

A continuous gasket is inserted during the production process.

STATIC FEATURES

TTACK® panels are classed as self-supporting in accordance with the definition in 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 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 the insulating material, caused by accidental overloads, is taken into account in the static calculation.

TOLERANCES (See UNICMI regulation)
Coating thickness: in accordance with reference standards for the products used.
Length: if ≤ 3000 mm ± 5 mm; if > 3000 mm ± 10 mm
Panel thickness: if ≤ 100 mm ± 2 mm; if > 100 mm ± 2%
Perpendicularity deviation: so = horizontal deviation
so ≤ 0.6 % of the nominal width covered
Out of square: max. 3 mm

PROTECTION OF METALLIC COATINGS
All panels precoated with the metallic coatings mentioned above are supplied on request with an adhesive polyethylene protective film to prevent damage to the coated layer. LATTONEDIL will not be held liable for any damage to the coating in the event that the material is to be supplied without the protective film.
The protective film must be completely removed during installation of the panels and, in any case, within thirty days of when the material is prepared. Panels still covered with the protective film must not be exposed to direct sunlight for long periods of time.
