SeaHawk - Premium Reflective Mylar – Commercial-Grade Mirror-Finish Reflector Sheeting Bonded to 110-Micron Heavy-Duty Non-Tear Poly Backing
Optimize your indoor cultivation facility's light efficiency, structural durability, and climate control consistency with the commercial-grade SeaHawk Premium Reflective Mylar. Specifically engineered to meet the strict architectural tolerances and biosecurity standards of large-scale wholesale nurseries, vertical farms, and advanced cultivation facilities, this specialized reflective lining acts as a high-performance perimeter envelope for your growing zones. Achieving peak photosynthetic photon flux density (PPFD) across your entire canopy requires absolute light containment and maximum reflection efficiency. Standard thin-gauge retail Mylar films frequently suffer from extreme creasing, effortless tearing, and rapid degradation under intense high-output grow light arrays. Our advanced, structural poly-bonded material solution permanently eliminates these operational bottlenecks.
The core architecture of SeaHawk Premium Mylar relies on a high-purity reflective film bonded directly onto a robust, 110-micron industrial black poly backing. This co-laminated engineering strategy provides exceptional tensile strength, drastically reducing material tearing, pinholing, and wrinkling during high-stress facility installations. Featuring an uncompromised mirror-smooth finish, this technical sheeting maximizes light bounce to reclaim lost perimeter illumination and drive deep lower-tier leaf photosynthetic activity. The heavy-duty black backing guarantees total opacity, preserving strict photoperiod isolation while ensuring the film naturally hangs straighter and stays flat against walls or frame infrastructure. To accommodate varying facility footprints and retrofitting projects, this premium material is supplied in a standard 1.2-meter roll width across two versatile lengths: a bulk 30-meter master roll for comprehensive room fit-outs, and an easy-to-handle 7-meter roll pre-measured for modular grow cells, propagation racks, or localized workstation isolation.
Best For: Enclosing high-output commercial indoor grow rooms, lining multi-tier vertical rack shelving, fabricating custom propagation cells, and strict dark-period photoperiod insulation.
Key Features & Technical Advancements
- 110-Micron Heavy-Duty Backing: Reinforced with a dense, industrial-weight black poly layer that drastically enhances tear resistance and mechanical longevity compared to unbacked foils.
- Super-Reflective Mirror Finish: High-purity polished metallic layer provides exceptional direct light reflection, throwing maximum available lumens back onto the edges of the crop canopy.
- Enhanced Structural Flatness: The specialized multi-layer composite construction resists curling and creasing, allowing the film to remain perfectly flat against flat boards, framing, or drywall surfaces.
- 100% Light-Tight Boundary Isolation: The heavy black poly backing serves as an absolute light blockout shield, preventing light leaks and protecting sensitive dark photoperiods from external pollution.
- Flexible Commercial Roll Capacities: Available in high-volume 30-meter rolls for large facility fit-outs, as well as compact 7-meter configurations for quick maintenance turnarounds or smaller grow tents.
- Streamlined Handling and Layout: Formulated with a fixed 1.2-meter width, making it perfectly sized for one-man installations, standard vertical rack boundaries, and wall section drops.

Advanced Environmental Conditioning & Reflective Layout Tips
- Maximizing Lower-Canopy PAR Delivery with Mirror Reflection: Mount the smooth mirror-finish side facing directly toward your plant layout. Because smooth Mylar creates specular (direct) reflections, adjust your overhead grow lights precisely to direct excess wall reflection into lower leaf zones, boosting under-canopy development without drawing extra power.
- Securing Flat Wall Fits and Eliminating Micro-Pockets: When fixing the film to grow walls, utilize heavy-duty spray tack, industrial hook-and-loop strips, or flat-headed staples. The rigid 110-micron poly backing allows you to pull the sheeting taut across vertical studs or drywall, avoiding sagging air pockets that can trap stagnant moisture or disrupt light pathways.
- Total Photoperiod Isolation and Seam-Sealing Protocols: When overlapping adjacent sheets during high-volume facility fit-outs, maintain a strict 5cm boundary overlap. Permanently secure and seal the joins using high-tack aluminum foil tape or heavy-duty black vinyl tape to create an airtight and completely light-tight barrier, safeguarding sensitive flowering cycles from ambient hallway light leaks.
- Facility Sanitation and Reflection Maintenance Loops: The durable poly backing prevents the material from buckling under routine washdowns. Between cultivation cycles, mist the mirror surface with a 10% solution of food-grade hydrogen peroxide or a specialized agricultural quaternary ammonium sanitizer. Gently wipe down with a soft microfiber mop or cloth to clear residual dust and mineral deposits, ensuring your high-reflectivity workspace remains clean and sterile.
Ideal For (Uses)
- Commercial Indoor Cultivation Facilities: An exceptional selection for lining large commercial grow spaces, providing a durable, high-efficiency reflective skin over raw walls, dividers, or insulation boards.
- Multi-Tier Vertical Propagation Racks: Perfect for space-restricted facilities looking to line the ceilings and walls of narrow shelving systems, turning standard racking units into highly enclosed, intensely illuminated cloning cells.
- Phenotype Isolation and Custom Grow Cells: Provides a clean, highly durable, puncture-resistant boundary layer ideal for segregating experimental mother lines, breeding zones, or sensitive genetic trial rooms.

Oversized Item Delivery Options
Since oversized items require special handling, we may need to provide a custom freight quote for your order and will contact you with an updated shipping rate.
Available options include:
✔ Delivery to your closest depot for pickup - default method
✔ Direct delivery - requires forklift on site
✔ Direct delivery with tailgate lift truck (extra fees apply)
✔ Forklift loading at our warehouse (no extra charge if you arrange your own freight)
✔ Direct truck delivery (available in Victoria)
Important Notes:
- Shipping costs vary by location and method
- Because of the forklift requirement, delivery to the nearest depot is the default option and will be the method used unless you contact us to request otherwise.
Business Delivery:
- Business delivery is available for commercial customers only
- If you select business delivery and your products are bulky, it is your responsibility to ensure you have appropriate equipment (including forklifts) to unload products from the delivery truck
- If you select business delivery and you are not a business, you risk your product not being delivered and may incur additional fees to retrieve your order
- Business delivery customers must provide a valid business address and contact information
- Additional fees may apply for failed delivery attempts due to lack of appropriate unloading equipment
Let us know your preference, and we'll arrange the best solution for you!
Important Note on Availability & Shipping
Our warehouse serves as our office and logistics centre rather than a retail showroom. Because we ship from multiple locations and manage high-turnover stock, not all items are available for immediate pickup.
Lead Times:
- In-Stock Items: Usually ready for dispatch the same day.
- Supplier-Dependent Items: Usually take 2–8 weeks to arrive, depending on supplier availability. Products from Adloheat may take 8–12 weeks to manufacture—they are made to order in Australia by a small business, and longer lead times reflect the care put into quality.
While we strive for fast delivery, some timelines are subject to supplier availability and are beyond our control. We appreciate your patience as we source the best quality gear for your project.
Biosecurity & Interstate Shipping Restrictions
Due to strict state biosecurity regulations, we are unable to ship some products to certain states and territories:
- Potting Mixes cannot be shipped to Western Australia (WA), the Northern Territory (NT), or Tasmania (TAS).
- Seeds cannot be shipped to Western Australia (WA).
Orders placed for these items to restricted states will be cancelled and refunded. It is the customer's responsibility to ensure that the items being ordered can lawfully be delivered to their state or territory.
