Attaching Greenhouse Plastic To Wood: Best Methods

how to attach greenhouse plastic to wood

There are several ways to attach greenhouse plastic to wood, including staples, screws, duct tape, rope, and grommets. Some methods are more permanent than others, and some are more effective at preventing tears in the plastic. For example, while staples are a budget-friendly option, they can create a lot of waste and may not withstand high winds. Screws with rubber washers are a slightly more expensive but longer-lasting alternative. Other options include using batten tape (non-adhesive vinyl or woven polypropylene tape), PVC clamps, and wiggle wire channels. When attaching greenhouse plastic, it is important to consider the size of the structure, the local weather conditions, and whether the covering will need to be removed or replaced.

Use staples, screws, nails, and duct tape

When attaching greenhouse plastic to wood, staples, screws, nails, and duct tape can be used in a variety of ways. One method is to staple the plastic directly to the wood frame, creating a secure and budget-friendly hold. Overlapping the plastic and using staples can further reinforce the attachment. However, duct tape is not recommended as a long-term solution as it may not withstand harsh weather conditions.

For added support and ease of replacement, screws can be used instead of or in conjunction with staples. Screws with neoprene or rubber washers can enhance the hold and make it easier to remove the plastic when needed. When using screws, it is important to ensure that the edges of the wood are smooth to avoid tearing the plastic.

Nails are another option for attaching greenhouse plastic to wood. Trim boards can be nailed over the wood to hide and strengthen the plastic edge. Alternatively, small plastic grommets can be driven through the plastic and into the wood using large-headed nails. Nails can also be used in combination with staples for added security.

When using staples, screws, or nails, it is crucial to ensure that the wood is free of sharp edges and splinters that could damage the plastic. Additionally, batten tape, a non-adhesive vinyl or woven polypropylene tape, can be stapled over the plastic to provide further reinforcement. This method creates a permanent attachment, so it may not be suitable if the greenhouse cover needs to be frequently removed.

Try lock channel and spring wire

The spring wire is PVC-coated and is used to secure greenhouse coverings into a lock channel. To install the spring wire, pull the plastic tight and wiggle the wire back and forth into the channel. Each section of wire is 6.5 feet long, so you will need to cut the wire to fit using bolt cutters or a metal saw.

Spring wire and lock channel are preferable to staples and batten board as they allow the grower to remove and reinstall the plastic without causing damage. This method also creates a contiguous seal, allowing you to install the plastic without damaging the greenhouse.

You can also use spring lock wire, or wiggle wire, to hold the air between two layers of plastic and help them inflate. This provides temperature consistency for your greenhouse, which is essential for plant growth. Wiggle wire also creates a stronger attachment, preventing air and wind from getting under the plastic and causing it to fail.

Use rope and grommets

Using rope and grommets is an effective way to attach greenhouse plastic to wood. This method is ideal for those who want to avoid the use of adhesives or hardware such as nails or screws.

To begin, unroll your plastic film lengthwise along the structure, ensuring that the label is visible from inside the greenhouse. Most plastic is folded to facilitate easy unfolding as you pull the corners. Have two people grab a corner of the film on the ends and begin lifting it over the hoops of the greenhouse. As you do this, work with the wind to avoid the plastic being pushed onto the ribs, making the job more challenging. Tennis balls can be placed on pole ends to protect the plastic when guiding it over the structure. They can also be tied into a corner of the plastic with rope and used to pull it over the length of your structure.

Once the plastic is in place, you can use rope and grommets to secure it. First, create holes in the plastic using grommets. Then, thread the rope through the grommets and tie it tightly to the frame. Braided Nylon Rope, similar to the type used for securing boats, is recommended for its ability to withstand the elements without stretching.

For added security, you can apply strong adhesive tape on both sides of the plastic before driving the grommets through. This method is particularly effective for heavier, thicker plastic and requires an Eyelet Hole Punch Set.

It is important to note that grommets and washers are a popular way of attaching greenhouse plastic to a wood frame, but they may not be suitable for all types of fabric or plastic. Smaller eyelets, for example, can pull loose with too much tension and may not be suitable for plastic, as the metal may not encase the edges properly.

Bury the plastic in a trench

Burying the plastic in a trench is an effective way to secure greenhouse plastic without damaging it. This method is simple and does not require additional materials or tools. It is also easy to adjust the tension on the plastic after attaching the top edge.

To bury the plastic in a trench, start by digging a trench that is approximately 6 to 12 inches deep and wide. This depth and width are sufficient to hold the plastic securely, even in severe wind conditions. Place the plastic inside the trench, ensuring that it is properly positioned and aligned.

Backfill the trench with soil, firmly packing it down as you refill the trench to ensure that the plastic is securely held in place. This method is not only effective in securing the plastic but also helps to maximize tension, especially after attaching the top edge.

Additionally, you can enhance the functionality of the trench by incorporating it into a water capture system. For example, you can direct the end of the trench to dump into a barrel or reservoir, allowing you to collect rainwater for watering your plants. This dual-purpose design not only secures your greenhouse plastic but also provides an eco-friendly and sustainable water source for your plants.

Opt for PVC clamps

Opting for PVC clamps is a great way to attach greenhouse plastic to wood. This method is one of the favourites and can be done by purchasing pre-made PVC clamps or making them yourself. The latter option gives you the freedom to customize the size of the clamps to fit your needs.

To make your own PVC clamps, you will need to cut out sections of a PVC pipe. The cutouts should be smooth, with no sharp edges that could puncture the plastic. The clamps should be designed so that they are tight and require some effort to snap onto the hoops.

If you don't feel confident in your ability to cut and make your own clamps, you can purchase pre-made PVC clamps online. These clamps can be screwed to a wood frame and then snapped into place, providing a secure hold for your greenhouse plastic.

Using PVC clamps is a more comfortable and convenient option than other methods, such as stapling or duct taping, which can create a lot of waste and are more likely to cause tears in the plastic. With PVC clamps, you can avoid these issues and create a strong, long-lasting hold for your greenhouse plastic.

Overall, opting for PVC clamps is a great choice for attaching greenhouse plastic to wood. It offers a secure, customizable, and convenient solution that will keep your greenhouse plastic in place without the risk of tears or waste.
