1.noise isolation: average Sound insulation ≥37dB(50mm);
2.smooth and clean: water-proof and fire resistance;
3.easy installation: hide hook with sealing gel ;
4.light and durable: easy transportation, stable chemical characteristics of the material, double side color steel;
5.strong heat preservation: different thickness suitable for different needs for the insulation;
6.strong compression and shock resistance: with the 36kg/m³ or more density wight, reasonable structure to keep the panels firm .

I. Food Cold Chain (Core Application)
1. Low Temperature Freezing Warehouse (-25℃ ~ -18℃)
Applicable: Meat, seafood, frozen food, ice cream for long-term storage
2. Fresh Preservation Cold Warehouse (0℃ ~ 5℃)
Applicable: Fruits, dairy products, fresh eggs, flowers for short-term preservation
3. Food Processing and Central Kitchen
Multi-temperature zone cold storage (-18℃~5℃): Pre-prepared food, semi-finished products classified storage
Low-temperature processing workshop, cooling room, rapid freezing tunnel.
4. Fresh Food Logistics and Supermarkets
Cold Chain Center, e-commerce warehouse, supermarket back-up cold storage
Chain restaurant small cold storage (quick assembly)
II. Medical and Biological Cold Chain (High Precision Temperature
III. Special Industrial Low Temperature Environments
IV. Cold Chain Transportation Equipment
V. Other Special Scenarios:
Aerated storage/Ice buildings / ice sculpture halls/Agriculture / Aquaculture
1. Line alignment
Use a laser instrument to mark: floor trench line, wall panel edge line, partition line, wall corner reference
The corner is the starting point for installation, ensuring that the first panel is straight and vertical
2. Installation of trench / base plate
Fix U-shaped trench (spacing ≤ 600mm)
Seal the base plate groove, make a tight connection, gap ≤ 2mm
Horizontal deviation ≤ 2mm/2m
3. Wall panel installation (core)
Step 1: Groove sealing
Uniformly apply sealing glue to the convex groove (φ6 - 8mm), use a 45° glue gun
Apply glue to the mushroom head bolt hole and the bolt body
Step 2: Vertical board and connection
Start from the corner, connect the convex groove upward and the concave groove downward
Control the board gap: 3mm ± 1mm (预留 cold shrinkage)
Vertical error ≤ 2mm/2m
Step 3: Fixation
Top: spacing ≤ 200mm;Middle: ≤ 300mm; Bottom: ≤ 150mm (densified)
Use L-shaped corner band +points to fix at the corner
4. Top plate installation
Sequence: Install first around, then in the middle
Four-point hoisting, level positioning, precisely fit with the wall panel groove
Fixation spacing ≤ 600mm, add anti-shear parts
Apply glue to the board gap + seal
5.inside and outside corner and special areas
Sunken corner: L-shaped corner board + double sealing + corner band
Sunken corner: Apply glue + glass fiber cloth for crack prevention
Door frame / window: Surrounding foaming + fireproof mud sealing + glue
Through-wall pipe: Ω-shaped compensator + seal + insulation bridge
6. Board gap sealing (double-layer process)
Internal: Polyurethane foam filling (7/10 full, leave expansion)
Surface: Low-temperature resistant silicone sealant, press concave arc shape (prevent water accumulation)
