When it comes to roofing solutions, PUF panels and UPVC roofing sheets are among the most durable, energy-efficient, and cost-effective materials available today. At Viraat Industries, we specialize in the manufacturing of high-quality PUF and UPVC products that are designed to perform in diverse environments. However, even the best materials can underperform if they are not installed correctly.
Improper installation can lead to premature wear, energy loss, water leakage, and reduced structural strength. Whether you’re a contractor, builder, or property owner, being aware of common installation errors can help you avoid unnecessary expenses, delays, and complications in the future.
In this blog, we’ll explore the top 5 mistakes to avoid when installing PUF or UPVC roofing panels—and how to do it the right way.
Ignoring the Manufacturer’s Guidelines
PUF Panel Installation Mistakes
Many installers make the error of not thoroughly reviewing or following the manufacturer’s installation manual. PUF and UPVC panels are engineered with specific structural and insulation properties, and deviating from the recommended method can compromise their performance.
The Right Approach:
Always follow the manufacturer’s guidelines provided by Viraat Industries or your supplier. These instructions cover critical aspects such as:
- Recommended screw types and spacing
- Panel overlap requirements
- Ideal slope and pitch for water drainage
- Handling and storage practices
By sticking to the official recommendations, you can ensure the product functions exactly as it’s designed to—delivering maximum durability, insulation, and weather resistance.
Improper Handling and Storage of Panels
The Mistake:
PUF and UPVC panels may appear sturdy, but mishandling them can lead to dents, cracks, or edge damage. Similarly, storing them incorrectly—such as stacking them on uneven ground or exposing them to harsh sunlight—can warp the sheets or degrade their quality.
The Right Approach:
Store panels on a flat surface in a shaded area and avoid stacking them too high. During transportation or movement, always lift panels with care instead of dragging them, especially over rough surfaces. For UPVC sheets, keep them covered to avoid UV exposure before installation, as prolonged exposure can impact surface integrity.
Incorrect Fastening Techniques
The Mistake:
Using the wrong type of fasteners or placing them improperly can lead to leaks, weak joints, or even roofing failure in high winds. Over-tightening screws on UPVC panels may cause cracks, while under-tightening can lead to loose panels.
The Right Approach:
Use recommended fasteners—typically self-drilling screws with EPDM washers—to ensure waterproofing and secure attachment. For PUF panels, ensure that the fasteners go through the metal facing and into the supporting structure.
Spacing of fasteners should also follow guidelines, typically around:
- 300–400 mm on overlaps and edges
- 500–600 mm along internal purlins
And most importantly, never fix panels too close to the edge where expansion or contraction is likely.
Neglecting Thermal Expansion and Contraction
The Mistake:
Both PUF and UPVC materials expand and contract with temperature changes. Installers who fail to account for this may end up with buckled sheets, broken fasteners, or noisy roofs.
The Right Approach:
Leave sufficient room for thermal expansion by not fixing panels too tightly. For UPVC sheets, allow for a slight gap in overlaps and use slotted holes when fixing to purlins to allow movement. For PUF panels, avoid rigid end-to-end contact—use appropriate sealants or gaskets.
Thermal movement might seem minor, but over time it can have a serious impact on your roof’s integrity.
Poor Overlapping and Sealing
The Mistake:
Improper panel overlapping or inadequate joint sealing can result in water seepage, which may cause rusting and structural damage over time, thermal loss, and even mold formation in PUF cores.
The Right Approach:
Overlap UPVC sheets according to wind direction—usually a minimum of one corrugation. In PUF panel installations, maintain a tight and aligned joint between panels and use compatible PU foam sealants or joint tapes to prevent gaps.
Additionally, for both PUF and UPVC panels, ensure proper side and end laps and consider using silicone sealant in high-moisture or coastal areas for extra protection.
Bonus Tips for Successful Installation and Avoiding PUF Panel Installation Mistakes
Work with Experienced Installers
Installation plays a major role in the long-term performance of your roof. Always hire trained professionals familiar with insulated panels and UPVC systems.
Inspect the Roof Framework
Make sure your roof’s structure is level, clean, and suitable for panel attachment before starting the installation. An uneven base can create stress points and shorten the life of the panel.
Weather Considerations
Avoid installing during rainy or high-wind conditions. Moisture trapped during installation can lead to internal condensation and reduce panel effectiveness.

Frequently Asked Questions
Inadequate sealing can result in air and moisture infiltration, reducing thermal insulation efficiency and potentially leading to mold growth or structural damage over time.
Misaligned panels can create gaps, leading to thermal bridges where heat transfer occurs, thus diminishing the insulation effectiveness and increasing energy costs.
While DIY installation is possible, professional installers have the expertise to ensure proper alignment, sealing, and fastening, maximizing the panels’ performance and longevity.
Regular inspections for seal integrity, cleaning to prevent debris accumulation, and prompt repairs of any damages help maintain the panels’ insulation properties and extend their service life.
