Raising the Bar in Daylighting & Cladding

Why SUNTUF® is the SMART Alternative to GRP Sheets

When considering sidewalls, roof lights, or façades for industrial and agricultural buildings, specifiers often opt for GRP sheets. However, are they truly the optimal choice?

Current performance requirements necessitate a superior solution. Palram’s SUNTUF industrial polycarbonate sheets offer enhanced performance, a cleaner appearance, and an extended lifespan, all while aligning with the profiles of most metal roofing systems.

Real-World Proof: 5-Year Case Study

In a long-term side-by-side comparison conducted in two identical machine shops, each measuring 12,910 ft², SUNTUF sheets were installed on one roof while standard GRP was used on the other.

Key Findings after 5 Years:

• Illumination Levels: GRP experienced a 64% drop, while SUNTUF saw only a 5% decrease.
• Artificial Lighting Demand: GRP required full-time lighting after Year 3, whereas SUNTUF required none.
• Energy Savings: SUNTUF provided 30% more cumulative energy savings, amounting to $8,562.92.
• Maintenance & Replacement: GRP sheets exhibited severe yellowing and reduced opacity, while SUNTUF panels continued to perform and appear as new.
