How to Verify (for Tomato Projects)
- Specify glaze correctly: low-iron + diffused (haze 50–70%) with optional AR for PAR gain. Ask for target LT (%) and haze in the PI/contract.
- Safety: require
EN12150(or ANSI Z97) tempering reports tied to batch/lot; confirm edge finishing and dimensional tolerance for your frame. - AR durability: request salt-spray/UV aging data, cleaning SOP and a written warranty (abrasion, hydrophilicity, coating peel).
- Packing & logistics: export crates with paper/interleave + desiccant + corner guards; crate photos/videos before sealing; insurance with exact spec on invoice.
- Pilot first: 5–10 m² sample cut to your sizes; check haze uniformity, scratches, condensation behaviour, and do a crate drop-test on site.
FAQ
Which thickness should I choose for tomato houses?
4 mm tempered is the most common for Venlo roof/walls. 3.2 mm exists for lighter frames, but verify wind/snow loads with the structure supplier.
Is AR coating worth it?
Vendors claim +2–3% LT for single/double-AR. In high-value crops (tomato), this can pay off; it adds cost and cleaning care. Evaluate ROI by climate and lighting strategy.
What should be in the purchase order?
Exact glass type (low-iron/diffused/AR), thickness, target LT & haze, tempering standard, cut sizes, edge finish, coating side(s), packing spec, warranty, inspection rights/penalties, Incoterms, and delivery milestones.
