ACRYLITE 16 mm Multi-Skin Greenhouse Panels (Resist and Alltop)
Pros
- 86% light transmission (Resist 16 mm) and 89–91% (Alltop 16 mm), against 72–76% for 16 mm polycarbonate
- Non-prorated, full-replacement warranties: 30 years against yellowing, 10 years on light transmission, 10 years on hail
- R-2.04, U-0.49 twin-wall insulation; the maker cites up to 40 percent energy savings over single glazing
- NO DRIP coating spreads condensation into a film instead of drops that scatter light and drip on plants
- UV-stable through the sheet, so a scratch does not expose unprotected plastic
- Stiff: a 47-inch-wide 16 mm sheet needs no cross supports for uniform loads to 15.7 lb per sq ft
Cons
- Roughly double the price of 16 mm polycarbonate, and freight only
- About 1 lb per sq ft, nearly twice polycarbonate's weight; check the frame
- Combustible, ASTM D-635 class CC2, with area limits in some codes
- Moves 1/16 in per foot with heat and moisture; wood battens and screws through the sheet will crack it
- Seasonal stock-outs are routine, and custom lengths under 20 sheets carry a repacking charge
ACRYLITE Corrugated Greenhouse Panels (High Impact Wave)
Pros
- 90 percent light transmission, and independent testing found 81 to 88 percent still coming through after ten years
- Same 30-year non-yellowing warranty as the multi-skin sheet, plus a 10-year hail and weathering warranty
- 3 mm sheet at about 0.8 lb per sq ft; the wave profile gives it the stiffness to span purlins
- UV-blocking, so plants and benches are protected
- The lowest-priced rigid acrylic glazing sold by the bundle
Cons
- Single skin: R-0.91, U-1.10, no meaningful insulation
- The corrugated profile needs matching foam closure strips and profiled fasteners at every edge
- Freight only, sold out in season, and 41-inch panels take more laps than 47-inch flat sheet
- Combustible acrylic with a 160°F service limit, same as the flat sheet
