What Are Sandwich Panels 40mm
sandwich panel 40mm are advanced composite building materials made by sandwiching a 40mm thick insulating core between two durable metal sheets. This core typically consists of materials like PIR, PUR, or mineral wool, providing excellent thermal insulation while keeping the panels lightweight. The metal facings give these panels structural strength, making them a reliable choice for roofing, wall cladding, and interior partitions.
At Shanghe, we focus on using top-grade raw materials and cutting-edge manufacturing processes to ensure every 40mm sandwich panel delivers superior performance. Our panels meet strict quality standards to offer consistent durability, insulation, and weather resistance, setting us apart in the market.
Compared to other thickness options, 40mm panels offer a balanced combination of insulation efficiency and material cost. Thicker panels provide higher insulation but come with extra weight and expense, while thinner panels might fall short in thermal performance. The 40mm thickness is an optimal choice for many commercial, industrial, and residential projects, especially where energy efficiency and structural integrity are key.

How to Choose the Right 40mm Sandwich Panel
Picking the right 40mm sandwich panel starts with understanding your project’s specific needs. Here’s what to focus on:
Assess your project requirements
- Think about how much insulation you need. For example, cold storage needs tighter thermal control than general roofing.
- Consider the panel’s structural role—will it support load or just cover surfaces?
- Don’t forget aesthetics if the panel will show on walls or facades.
Choose the right core material by budget and performance
- PIR sandwich panels offer excellent thermal insulation and fire resistance, great for energy-efficient buildings.
- PUR sandwich panels are cost-effective and lightweight, perfect for general roofing or interior walls.
- Mineral wool panels provide superior fireproofing and sound insulation but may cost a bit more upfront.
Evaluate your supplier carefully
- Look for a company that delivers on quality and timing.
- Check if they offer reliable customer support and installation guidance.
- Consider their reputation and reviews, especially in the U.S. market.
Factor in your local conditions
- Weather plays a big role. For example, harsh winters demand panels with better insulation and moisture resistance.
- Review local building codes and regulations to make sure the panel meets all standards.
- Choose a supplier with a nearby warehouse or fast shipping options to avoid delays.

Installation and Maintenance Tips
Installing 40mm sandwich panels right is key to getting their full benefits. Here’s a quick guide for smooth setup and lasting performance:
Best installation practices Ensure the surface is clean and level before placing the panels. Use proper fasteners and follow Shanghe’s recommended spacing to keep panels secure. Overlap edges correctly to prevent water leaks and air gaps. Handle panels carefully to avoid dents or damage to the PIR, PUR, or mineral wool core. Allow for thermal expansion by leaving slight gaps where needed. Maintenance for long-lasting use Clean panels regularly with mild soap and water—avoid harsh chemicals. Check seals and joints every few months to catch any cracks or gaps early. Inspect for signs of corrosion or damage, especially around fasteners. Replace damaged panels quickly to maintain insulation and weather resistance. Safety during installation Wear gloves and safety glasses to protect hands and eyes when handling panels. Use proper lifting techniques or equipment since even lightweight panels can be awkward to move alone. Follow local building codes and guidelines for construction safety. Support from Shanghe
