Riga Shade Net for 14x14 Riga IV or IVS Greenhouses
Aluminet 50% Shade Net for Riga IV & Riga IVs Greenhouse
⚠️ Custom Made to Order — Ships in 4–5 Weeks. This shade net is custom manufactured when ordered and cannot be expedited. Please plan accordingly before purchasing.
The Riga Aluminet Shade Net is a 50% aluminum reflective shade net designed for exterior installation on the Riga IVs (7x14) and Riga IV (9x14) greenhouses. It blocks approximately half of incoming solar radiation during the hottest part of the day, reducing interior temperatures and protecting heat-sensitive plants — while still allowing 50% of sunlight through the mesh structure for continued plant growth. The net is sized at 14' wide × 14' long — wider than the greenhouse footprint — so it wraps over the roofline and down the sides for full coverage. Roof vents remain fully functional with the shade net installed.
What’s Included

Why Use a Shade Net on a Riga Greenhouse?
Polycarbonate greenhouses transmit a high percentage of solar radiation, which is ideal for winter growing but can cause overheating in summer — even with roof vents open. Interior temperatures can exceed 100°F on hot sunny days, stressing or killing heat-sensitive plants. The Aluminet shade net reduces solar heat gain by approximately 50%, keeping the interior cooler during peak summer heat while still providing sufficient light for most crops. Unlike solid shade cloth, the aluminum reflective mesh reflects heat away from the greenhouse rather than absorbing it, making it more effective at reducing radiant heat load.
Aluminet vs. Standard Shade Cloth
| Feature | Aluminet (this product) | Standard Shade Cloth |
|---|---|---|
| Material | Aluminum reflective mesh | Woven polyethylene or polypropylene |
| Heat Reduction Method | Reflects solar radiation away from greenhouse | Absorbs solar radiation (can re-radiate heat) |
| Light Transmission | ~50% (this net) | Varies by shade percentage |
| Durability | High — aluminum resists UV degradation | Moderate — UV exposure degrades over time |
Frequently Asked Questions
Why does the shade net measure 14' wide when the greenhouse is only 7'8" or 9'8" wide?
The 14' width is intentional — the net is designed to drape over the peak of the roof and hang down both sides of the greenhouse. This provides full coverage of the roof and upper side panels where solar heat gain is greatest. The extra width ensures the net reaches far enough down the sides to be secured with the brass grommets.
Does this fit both the Riga IVs (7x14) and the Riga IV (9x14)?
Yes — the 14' × 14' net fits both models. The Riga IVs is 7'8" wide and the Riga IV is 9'8" wide; both are 14' long. The 14' net width provides adequate overhang for both widths, and the 14' net length matches the greenhouse length exactly.
Can I still open the roof vents with the shade net installed?
Yes — the shade net is designed to allow the roof vents to open normally. The mesh is flexible and the net is positioned so that the roof windows can push through or lift the net as they open. The Riga IVs and IV each have 2 automatic roof openers; ventilation is not blocked by the shade net.
Is this shade net for interior or exterior use?
Exterior use only. The net is draped over the outside of the greenhouse. Exterior installation is more effective at reducing heat gain because it intercepts solar radiation before it enters the polycarbonate panels, rather than after.
How long does it take to receive this shade net?
This shade net is custom manufactured when ordered. Lead time is 4–5 weeks from the order date. It cannot be expedited. If you need the net for a specific date (e.g., before summer heat peaks), order at least 5–6 weeks in advance.
How is the shade net attached to the greenhouse?
The net has a taped edge with brass grommets for secure attachment. You can use bungee cords, rope, or zip ties through the grommets to secure the net to the greenhouse frame. The grommets are positioned around the perimeter of the net for even attachment points.
