HIGH THICKNESS WALL PANEL
Dry panel for cold rooms that allows insulation to be obtained through the use of gaskets and sealants. The 200 mm thick version features a labyrinth joint, a conformation that increases the vapour barrier standards, as it has a larger adhesion surface and guarantees greater thermal insulation and risks associated with air leaks.
– 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
30 – 40 – 50 – 60 – 80 – 100 – 120 – 150 – 160 – 180 – 200 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
One-component thixotropic polyurethane sealant or other silicone sealant (applied on site).
The perfect configuration of the labyrinth joint allows the thermal insulation performance of the wall to be significantly improved.
With the same thickness of the panels, the contact surface between the elements in the labyrinth joint is greater compared to the classic male-female one.
This leads to greater resistance and tightness to the passage of air between neighbouring environments that have pressure and/or temperature differences.
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.
