Alamentti acid-resistant wall sandwich panel

Durability, chemical resistance and hygiene in one system.

The Alamentti acid-resistant sandwich panel has been developed for the most demanding operating conditions—where standard building materials are not sufficient. Thanks to the use of acid-resistant stainless steel facings and insulation cores (EPS or mineral wool), the panel offers high resistance to chemicals, moisture and temperature, while also meeting sanitary and fire safety requirements.

An acid-resistant panel for the food industry—and beyond

Alamentti acid-resistant panels are specifically designed for facilities exposed to intensive action of acids, alkalis, water vapour, professional disinfectants and elevated humidity. They are successfully used in the following industries and facilities:

• Meat, fish and dairy processing plants
• Slaughterhouses, distilleries and professional industrial wash bays
• Laboratories and clean areas with heightened cleanliness requirements
• Cold stores and specialist process/technical rooms

Advanced construction and technical parameters

Facing specification:

• External and internal facings: acid-resistant stainless steel with a smooth surface, ensuring easy cleaning and outstanding resistance to chemicals and corrosion processes.
• Optional: Upon request, a variant is available with stainless steel facing on one side only and a standard facing on the other.

Insulation core options:

• EPS (expanded polystyrene) – low self-weight, excellent thermal insulation performance and easy installation
• Mineral wool – enhanced acoustic insulation and significantly higher fire performance

Dimensional parameters:

• Modular width: 1000 mm or 1150 mm
• Available panel thicknesses: 40 to 250 mm (standard in 20 mm increments)
• Maximum production length: 12,500 mm

Available profiles:

• External profiling: GL, RO, MF, SN, MA, LA, FP, P47 (P47 profile available only for the 1000 mm module)
• Internal profiling: GL, RO, LA, P25, P47

Key advantages and technical performance

1. Exceptional chemical resistance – the use of high-grade acid-resistant stainless steel provides excellent resistance to strong acids, alkalis and aggressive

2. Hygienic surface to the highest standards – a smooth, non-stick surface structure significantly simplifies cleaning under strict sanitary conditions.

3. Advanced joint system – tongue-and-groove joints with gaskets ensure high airtightness and easy wash-down/cleaning.

4. Flexible choice of insulation core – parameters can be tailored for thermal insulation, acoustic performance and fire resistance requirements.

5. Efficient and cost-effective installation – low self-weight (especially with EPS) and prefabricated design enable fast, economical installation.

Summary

Alamentti acid-resistant wall sandwich panels are an ideal solution for constructing safe, hygienic and durable facilities operating in aggressive chemical environments. The combination of premium-grade acid-resistant stainless steel with insulation cores provides unmatched design flexibility and excellent technical performance—making these panels the optimal choice for investors who do not accept compromises in durability, safety and hygiene in industrial facilities.
