Quantity pricing:
5 or more $72.58 each

Insulated Glazing Panel

This double-walled polycarbonate is one of the most cost effective greenhouse coverings available. It is popular because of its insulation value, light weight, toughness, easy handling, rigidity, long service life, high light transmission, and neat appearance. Use TwinWall for new installations or reglazing an existing greenhouse. It is an excellent replacement for single-pane roof glass. Most aluminum and glass greenhouses can easily be insulated with TwinWall using the existing glazing clips or bar caps.

Heat Saving: TwinWall channels trap air between 2 walls. This gives up to 50% energy savings over single-wall coverings, keeps your plants warmer, and reduces heating costs.

Light Transmission: TwinWall has 85% of the light transmission of single glass - plenty for growing plants. It also diffuses light better to reduce plant sunburn. Because of the insulating effect of the double wall, there is less condensation (and more light transmission) and little or no dripping from overhead. A special exterior surface coating resists weathering and triples the life of TwinWall over untreated polycarbonate. R Value = 1.6

Precut TwinWall Panels, 6 mm: The flutes (channels) run the length of the panel. Install panel with flutes vertical. Panel ends should be capped or sealed with a special tape that allows interior condensation to escape. Dimensions + or - 1/8".

10 year limited warranty on properly installed MultiWall polycarbonate against
- premature yellowing
- a loss of more than 10% of the original light transmission

Warranty may vary with different manufacturers.

Specifications & Additional Help Files

Sheets come with a thin film on both sides. Do not remove the film until it is ready to be installed. Peel off the film and mark which side of the sheet has the colored or labeled film on it. This side is the outside, which is UV protected.

When prepping the TwinWall for installation, some sheets may need to be cut to size. This is done very simply by using either a power circular saw equipped with a triple chip fine-tooth blade or by a razor knife. It is recommended to make the cuts on both sides of the sheet to ensure a clean cut.

Trouble Shooting:
If film isn't peeling off very easy, the sheet may not have been protected from the sun or was left in a hot environment. Try applying soapy water to the surface and peeling off the film, using caution not to scratch the surface.

To clean TwinWall Panels rinse sheet with lukewarm water. Wash sheet with a mild soap (Freon T.F., Joy, Palmolive Liquid, Top Job, VM&P Grade Naptha, Windex with Ammonia, or Charley's Brillianize #1657) and lukewarm water. Use a soft cloth or sponge and gently wash to loosen remaining dirt and grime. Do not scrub or use brushes or squeegees. Repeat rinse and dry with a soft cloth to prevent water spotting. Here is a list of cleaning products NOT to use on polycarbonate: Lysol, Pinesol, Butyl Cellosolve, Isopropanol, Formula 409.

Common Recommendations:
When preparing sheets for installation, it is recommended to seal the top end of the sheets. This may be done using Aluminum Tape item #1512. To allow moisture to escape from the channels of the polycarbonate, use a tracing wheel to perforate the tape on the top end of the poly sheet.
