MW CH
Product description
MW CH is a cold storage sandwich panel with a hard mineral wool core, available in 100–250 mm thicknesses with 1000 and 1140 mm modules. Class A2-s1,d0 makes it the preferred choice in cold storage facilities with fire requirements — cold stores and freezers in commercial, industrial and logistics buildings where the regulator or insurer excludes the use of PIR. Fire resistance reaches EI 240 at maximum thicknesses. Core lambda 0.044 W/(m·K) is higher than PIR — however the non-combustible character of the wool and acoustic properties (Rw = 31 dB) compensate for this parameter in applications with strict fire requirements. The product is certified by PZH.
Construction and features
- Profiled steel facing gives walls an aesthetic appearance
- Large lock profile radius keeping the paint protective coating intact
- Double lock joining the panels ensuring high fire-tightness performance
- Hard mineral wool core with very good fire resistance and acoustic performance

- freezer walls (temperature below 0°C) with class A2 requirement
- industrial buildings with enhanced fire requirements and refrigeration
Benefits for designers and contractors
- Class A2-s1,d0 — non-combustible — the only viable option when regulations or insurer rule out PIR in cold storage zones
- EI up to 240 — highest fire resistance among cold storage panels in the MW line
- 5 thicknesses (100–250 mm) — full cold storage spectrum from cold rooms to deep-freeze chambers
- Rw = 31 dB — additional acoustic insulation alongside the non-combustible core
- PZH hygiene certificate — hygienic safety for food facilities
- Two module widths — 1000 and 1140 mm for design flexibility
