Suntuf BH is Palram’s flagship 2.8 mm corrugated sheet, three times thicker than standard polycarbonate roofing and engineered for projects that demand exceptional impact strength, quiet rain performance and 100 % diffused daylight. The prismatic beehive texture scatters light evenly, cutting harsh glare while still brightening the space beneath. Made from UV-stabilised polycarbonate, every sheet blocks 99.9 % of harmful UV rays, shrugs off hailstones and maintains clarity in temperatures from –50 °C to +120 °C. Compliance with AS/NZS 1530.3 and a 10-year weather-breakage warranty give long-term confidence for both residential and commercial builds.

Why specify Suntuf BH?
- Maximum resilience – laboratory tests show up to 50 % greater hail resistance than conventional corrugated sheeting, with an impact rating of 75 J (ISO 6603-1 E50).
- Thermal comfort – the honeycomb prism disperses solar radiation, lowering internal heat build-up without the need for tints that darken the area below.
- Low-noise profile – the extra mass cuts rain drumming compared with lighter 0.8 mm sheets, making alfresco areas more enjoyable.
- Fire safe – self-extinguishing classification B-s1-d0 (EN 13501) for peace of mind in bush-fire prone zones.
- Easy installation – lightweight (≈3 kg m²), drills and cuts with standard tools, and fixes with 65 × 14 g Clearfix screws and matching infill strips.
Typical applications
Pergolas, patios, verandas, carports, covered walkways, sunrooms, greenhouse roofs and architectural canopies where glare-free daylight and high impact resistance are essential.
