WFJ

HIGH THICKNESS WALL PANEL WITH FOAMED JOINT

The choice of the high thickness WFJ panel requires on-site foaming, i.e. the injection of polyurethane inside the connecting profiles between the panels, guaranteeing completely watertight walls and ceilings. Ideal for low and very low temperature cold rooms.

– The specifications below are not to be considered product standards, but vary depending on the design needs and what is required during the contractual definition phase. –

DIMENSIONS

Width 1015 mm.
Length upon request from continuous production process.

THICKNESSES

100 – 120 – 140 – 150  – 160 – 180 – 200 – 220 – 240 mm
Panels of not standard thicknesses can be supplied upon request previous agreement on minimum quantities.

SUPPORTS

  • FE S250GD galvanized, pre-painted or plasticized galvanized steel.
  • Stainless steel.

INSULATION

Polyurethane resins (PUR) and (not standard) polyisocianurate foams (PIR), density 39 ±2 Kg/m³.
Declared value of thermal transmittance for a panel after 25 years of its installation, (Appendix C – EN 13165) Initial value of thermal conductivity: λ = 0,020 W/(mK).

JOINT

In the illustration can be seen the foamed joint in two stages:

  1. Before foaming with the containment profiles.
  2. Section of the completed foamed joint.

 

The foamed joint is the solution that definitively solves the problem of thermal bridges in low temperature cells.
The foaming carried out inside the joint makes the wall monolithic and completely sealed against the passage of air, gas or steam.
This solution requires specialized personnel and equipment designed for this type of application and is indicated in cases where there are extreme environmental conditions.

PROTECTIVE TREATMENT

  • Pre-painting with polyester.
  • Superpolyester (HD).
  • PVDF.
  • Polyurethane PUR/PA.
  • Plastisol.
  • Plasticized PVC with thicknesses between 15 e 200 µm.
  • Availability on request of other films and non-toxic coatings for occasional contact with food.

INSIGHTS PIR FOAM

On request is available in PIR foam version (polyisocyanurate), a particular polymeric structure that guarantees excellent characteristics of fire behavior. The entire range of ISOLPACK panels has been certified in Class B-s2,d0 at CSTB (France) and at KIT (Germany) in compliance with UNI EN 13823 (SBI) * where, “B” expresses the quantity of heat produced during the first 600 seconds of the test <7.5 MJ (best value obtainable for foamed products); “S2” represents a very low development of the fumes and “d0” indicates the absolute absence of drops and/or inflamed particles. In last years, the SBI test has become a standard requirement in Europe for fire behavior of building materials. The new European standard for sandwich panels – UNI EN 14509 – uses the SBI system for fire classification purposes. ISOLPACK is the only one in Italy to design light, highly insulating applications with unequaled fire reaction requirements. In many cases it can replace the rock wool panel considering its fire reaction characteristics combined with the very high thermal insulation power.

EPD CERTIFICATION (CAM)

The entire range of roofing and wall panels in steel and aluminium in PIR, PUR and mineral wool, single metal sheet panels and corrugated metal sheets in steel and aluminium, possess the EPD type III – EN ISO 14025 certification, meeting the requirements of compliance with the regulation construction DM 23 June 2022, and satisfying the required CAM criteria.
