Frequently Asked Questions About Sandwich PUF Panels

Introduction

Now energy efficiency, quick construction, and long-lasting durability have become criteria for the material selection in modern construction. The sandwich PUF panel is among the most revolutionary materials satisfying these requirements-a light building solution with great insulation used in warehouses, cold storages, modular houses, and industrial roofs.

But what exactly are these panels? And what makes them so popular? Whether you are a contractor, an architect, or a facilities manager looking for roofing and walling systems at a price, PUF panels will serve as a major highlight for you to explore and make an informed decision.

At MountRoof, a trusted name in PUF panel roof sheet manufacturing with years of industry experience, we’ve compiled this comprehensive FAQ guide to address the most common queries about sandwich PUF panels, their features, benefits, applications, and key factors to consider when selecting the right solution for your project.

1. What Are Sandwich PUF Panels?

These PUF panels are manufactured as pre-engineered building components and consist basically of three layers: a core of polyurethane foam bonded between two outer metal sheets, generally of galvanized steel, aluminium, or colour-coated ones. It is called “sandwich panel” construction from the layered build, giving superior structural integrity and insulation.

✅ Key Features:

• High thermal insulation
• Moisture, fire, and pest resistance
• Quick installation due to modularity
• Lightweight yet durable
• Low maintenance over decades

Use Cases:

• Cold storage and refrigerated units
• Clean rooms and pharmaceutical labs
• Pre-engineered buildings
• Roofs and walls of factories and warehouses
  

Temporary site offices, kiosks, and mobile shelters

MountRoof PUF panels are manufactured using high-density foam that meets stringent IS Standards, ensuring consistent quality and performance. These panels offer excellent structural strength combined with superior resistance to moisture, weather, and environmental wear and tear. Their lightweight yet durable nature makes them an ideal choice for constructing temporary site offices, kiosks, mobile shelters, and other modular structures that require quick installation and reliable insulation.

2. What are the advantages of using PUF panels in the construction industry?

Who would not want to use panels that benefit contractors, developers, or end-users from so many aspects? Inferior benefits can increase the demand for PUF panels.

🔹 Thermal Performance

PUF panels stop heat transfer and so are good candidates for cold rooms, projection-free, warehouses, and buildings within highly extreme climates. It cuts energy bills as the possibility of artificially heating or cooling a place is reduced.

🔹 Easy and Fast Installation

Pre-fabricated panels mean that the installation process will take less time and require fewer labor hours, getting the project ready sooner and saving on costs.

🔹 Durability

With corrosion resistance, waterproof, fire-retardant (B2 grade), and free from termites and fungus, the superior properties of PUF panels guarantee durability.

🔹Lightweight

Being lightweight in nature, sandwich panels, coupled with their high strength, thus reduce the weight of structures and simplify logistics.

🔹 Low Maintenance

Mount roof panels with special protection resist dust and weathering, rendering surface cleaning and maintenance almost negligible.

3. What Are the Applications of Sandwich PUF Panels?

PUF panels are incredibly versatile and are used across various industries:

4. How Long Do Sandwich PUF Panels Last?

PUF panels, when manufactured with quality materials and proper insulation density, can last for 25–30 years or even longer with minimal maintenance. The metal skins protect the foam core from external elements, and coatings (like polyester or PVDF) enhance UV resistance.

Mount Roof panels come with corrosion protection and superior joint sealing to extend the panel’s lifespan in diverse climates.

Pro tip: Regular inspections and cleaning can further extend the panel’s life.

5. How to Choose the Best PUF Panel Manufacturer? 

Since in finishing the project, all safety, insulation, and quality measures must be met, it is of utmost importance for you to choose a steadfast PUF panel manufacturer for your project.

🔍 Factors to Consider:

• Foam density and thermal performance
• Sheet thickness and metal type
• Manufacturing certifications (ISO, ISI)
• Customisation options (lengths, profiles, coatings)
• Delivery timelines and installation support

At MountRoof, we offer:

• ISO-certified manufacturing
• Custom design and sizing
• On-time delivery across India
• Competitive pricing with no compromise on quality

6. Is Everything About PUF Panel Eco-Friendly?

Even so, PUF Panels ensure energy efficiency, limit carbon production, and limit resource use with regard to traditional brick-and-mortar construction. As the foam has a low GWP and is CFC-free, so it is suitable for green buildings.

Steel and aluminium outer sheets can also be recycled, further strengthening the cause of sustainable construction.

7. What Is the Difference Between PUF Roof Panels and Wall Panels?

Both the core material is similar but differ in profile design and thickness:

• Roof Panels: Usually trapezoidal/ribbed for load distribution, with anti-leak overlaps
• Wall Panels: Flat or lightly profiled for better aesthetics

The thickness may range from 30mm to 150mm, both for the roof and wall panels, according to application requirements.

8. What Sizes and Thickness Are Available?

PUF Panels are typically varying in: 

Width: 25 mm, 30mm, 50mm, 75mm, 100mm, 120mm, 150mm, 200mm Plank Size 

Length: 55 feet (Customizable)

Width: 1060mm (approx., effective coverage)

MountRoof shall customize the dimension of the panels as per your project structure and insulation needs.

9. Are There Any Limitations to Using PUF Panels?

While PUF panels are incredibly versatile, there are a few considerations:

• It may not be ideal for multi-storey load-bearing structures
• Requires proper joint sealing to prevent thermal bridging
• Can deform under very high mechanical stress if not properly installed

However, with a trusted supplier like MountRoof and expert installation, these limitations can be mitigated effectively.

Final Thoughts

Sandwich PUF panels qualify as a very innovative and sustainable solution for modern construction needs. Their balance between thermal performance, durability, ease of installation, and low maintenance obviously makes them very attractive for many applications.

So the PUF panel manufacturer you choose will make an enormous difference on cold storage, clean rooms, and prefab office developments.
