Coreboard – 1.8m x 1.2m Horticultural Cladding (4.0mm / 750GSM)

Our 1.8m x 1.2m Coreboard is a high-performance, extruded polypropylene sheet engineered for the demanding environments of professional nurseries and agricultural facilities. Featuring a twin-wall construction with two flat skins connected by vertical ribs, this 4.0mm thick board offers a superior strength-to-weight ratio, making it an ideal choice for cladding growing structures, creating bench liners, or providing durable weather shielding.

Specifically manufactured with advanced UV stabilisers for Australian conditions, this 750GSM Coreboard is designed to resist brittleness and degradation under intense sun exposure. The polypropylene co-polymer material is naturally water-resistant, non-toxic, and highly resistant to common horticultural chemicals and fertilisers. Whether used for temporary partitioning, protective signage, or structural lining, Coreboard provides a cost-effective, impact-resistant, and 100% recyclable solution for modern horticultural projects.

Key Features and Benefits

• Twin-Wall Structural Integrity: The ribbed extrusion provides excellent rigidity and impact resistance while remaining remarkably lightweight and easy to handle.
• Advanced UV Stabilisation: Engineered to withstand prolonged outdoor use, ensuring the board maintains its physical properties and structural strength over time.
• Hygienic & Water Resistant: The non-porous surface is easy to clean and does not support the growth of rot or fungus, making it ideal for sterile nursery environments.
• Chemical & Toxin Resistance: Safely stands up to the rigours of agricultural sprays, fertilisers, and cleaning agents without degrading.
• Easy Fabrication: Simple to cut, fold, and convert with standard tools, allowing for rapid on-site customisation for benches, shields, or transport dividers.

Installation & Best Practice

To get the most out of your Coreboard panels, consider these professional application tips:

• Fixing & Mounting: For cladding applications, ensure panels are secured with broad-headed screws or washers to distribute pressure and prevent pulling through in high winds.
• Edge Sealing: If using in environments where debris or moisture buildup inside the flutes is a concern, the open ends can be sealed with specialised tape or u-profiles.
• Cutting: The material can be easily scored and snapped or cut through with a heavy-duty utility knife for precise fitting around greenhouse frames or benching.

Ideal Applications

• Growing Structure Cladding: Providing a durable, lightweight skin for specialized propagation areas or protective shelters.
• Nursery Bench Liners: Creating a flat, cleanable surface for tubestock and seedling trays that resists moisture and chemical spills.
• Signage & Labelling: A perfect substrate for weather-proof point-of-sale signs or block identification in retail and production nurseries.
• Protection & Partitioning: Creating temporary windbreaks, equipment shields, or hygienic dividers within packing sheds and laboratories.

FAQs

Is Coreboard the same as Corflute?
Coreboard is a similar twin-wall polypropylene product, often referred to generically as Corflute. Our Coreboard is specifically chosen for its horticultural-grade durability and 4.0mm thickness, which offers more rigidity than standard 2.5mm or 3mm variants.

Can I use Coreboard for permanent greenhouse roofing?
While Coreboard is highly durable and UV stabilised, it is generally used for side cladding, shielding, or temporary structures. For permanent high-clarity roofing, we recommend our specialized polycarbonate or greenhouse film ranges.

Is the material safe for edible crops?
Yes. Polypropylene is non-toxic and chemically inert, making it safe for use in close proximity to vegetables, herbs, and other food-producing plants.
