Cladding elements (PERLITTI cladding element) is mineral board based on MgO/MgSO4 binders, filled by filler (e.g. SiO2 or sawdust), and with glass-fibre mesh reinforcement on both sides. These cladding elements are characterized by density (980 – 1080) kg/m3, minimal value of the equivalent bending strength 6,0 N/mm2. Thickness of cladding element is 12 +0,5 mm and area weight is 13 kg/m2.

Cladding fixing devices

The cladding elements are mechanically fastened to the subframe by through visible punctual fixings (screws). Screws are made of stainless steel minimum Class C3, and differ according to the used subframe:

Wooden subframe: Screw, type (4,0 x 40) mm

Metal subframe: Screw, type (4,2 x 32) mm

Only screws made of stainless steel must be used.

• Subframe can be in two variants:

Wooden subframe (alternative 1) is formed by vertical and horizontal studs (the dimensions of vertical studs are min. (30×98) mm and the dimensions of horizontal studs are (48X98) mm) as defined in EN 14081 1, subframe fixing devices between vertical and horizontal studs (screws are made of stainless steel minimum Class C3, type (6×100) mm) and fixing devices between vertical studs and substrate (screws are made of stainless steel minimum Class C3, type (5×90) mm).

Wooden subframe (alternative 2) is formed by vertical studs (the dimensions of vertical studs are min. (30×98) mm as defined in EN 14081-1 and fixing devices between vertical studs and substrate (screws are made of stainless steel minimum Class C3, type (5×90) mm).

Metal subframe is formed by vertical profiles (the vertical profiles are made of stainless steel, thickness 1 mm and they are formed by 2 pieces of profiles shaped U (channel no. 1, dimensions (36×90) mm and channel no. 2, dimensions (42×92) mm)), washer to keep channel no. 1, firmly to substrate (the washer is made of stainless steel minimum Class C3), fixing devices between channel no. 1 and channel no. 2 from both sides (self-drilling stainless steel screws (4,5×25) mm) and auxiliary components e.g. thermos stops which is placed between channel no. 1 and substrate and reduce thermal bridges (material: XPS 700, dimensions (10x50x90) mm).

• Ventilated air space: A layer air between the substrate and cladding elements. The minimum recommended width of the ventilated air space is 25 mm for wooden subframe and for 30 mm for metal subframe.

Auxiliary components: The fixing devices (between subframe and substrate and between Anchorage to substrate). The fixings between the subframe and the substrate are not part of the kit, therefore have not been assessed, even so it is important define type, position and number of anchorage according to the substrate material and the resistance required due to the envisaged actions and when possible, CE marking according to the ETA via EAD is recommended.

2. Specification of the intended use(s) in accordance with the applicable European Assessment Document (hereinafter EAD)

2.1 Intended use The PERLITTI ventilated facade system is intended to be used for external wall claddings in ventilated facade (rainscreens) to be fixed to external vertical walls. They can also be used on inclined surfaces where are not exposed to precipitation. The substrate walls are made of masonry (clay, concrete or stone), concrete (cast on site or as prefabricated panels), timber or metal frame in new or existing buildings (retrofit).

The kit is a non-load-bearing construction element. They do not contribute directly to the stability of the wall on which they are installed but can contribute to durability by providing enhanced protection from the effects of weathering. The kits can improve thermal resistance of walls by applying thermal insulation directly on the wall substrate.

The provisions made in this European Technical Assessment are based on an assumed working life of 25 years as minimum, provided that the cladding kits are subject to appropriate use and maintenance.

Visual inspection of the facade system, Repairing of localized damaged areas due to accidents,

The aspect maintenance with products adapted and compatible with the facade system (possible after washing or ad hoc preparation). Regarding the panels: Appearance of any damage such as cracking, delamination or detachment due to permanent and irreversible deformation. ETA 19/0732 of 24/11/2019 – page 5 of 27 060-047384 English transtation by TTIC Prague – branch Brno

• Regarding metallic components: Presence of corrosion or water accumulation.

Necessary repairs should be performed as soon as the need has been identified.

It is important to be able to carry out maintenance as far as possible using readily available products and equipment, without spoiling appearance. Only products which are compatible with the facade system shall be used.
