How to Order the Correct Width and Length
Width
Our standard screen widths are designed to fit most greenhouse section widths:
| Screen Width: Meter / Feet |
Suitable for Section Width: |
|
| 3.35 m / 11.0 ft | (*) 3.00 – 3.20 m / 9.8 – 10.5 ft | |
| 4.30 m / 14.1 ft | 4.00 m / 13.1 ft | |
| 4.70 m / 15.4 ft | 4.50 m / 14.8 ft | |
| 5.30 m / 17.4 ft | 5.00 m / 16.4 ft | |
| 5.70 m / 18.7 ft | 5.40 m / 17.7 ft |
(*) A 3.20 m/10.5 ft width requires a separate, fixed strip for proper closure of the screen
Length
A little extra length should be ordered so that the installed screen is long enough without being tensioned. We advise you to follow the guidelines below.
For all screen types: order at least 1.5% extra
Order Calculation:
| Net Greenhouse Size | |
| + | 1.5% Overhang_____ |
| = | Number of Meters/Feet to Order |
Sufficient overhang is important for correct installation. Keep in mind when it comes to overhang, it's easier to cut off extra material later than add extra.
We recommend the following overhang sizes at different screen lengths:
| Screen Length | Size of Overhang | |
| 10 - 50 meters/ 33 - 164 feet | Min 0.7 meters / Min. 2.3 feet | |
| 50 - 100 meters / 164 - 328 feet | ±1 meter / ±1 3.28 feet | |
| > 100 meters / > 328 feet | > 1 meter / 3.28 feet |
Example:
A greenhouse with 6 trusses, truss length 8.00 meters:
6 x 8.00 m = 48.00 m - (0.10 m + 0.10 m) = 47.80 m + 1.5% = 48.52 meters
(Subtract 2 x 0.10 m because end wires are usually 0.10 m from the gable)
Overhang 2 x 0.7 meters
Total order length: 49.95 m
