Ultimate FAQ Guide To Polycarbonate Greenhouse Panel

Constructing a greenhouse panel is a tough task.

There are a lot of factors to be considered before deciding on the rooftop.

One major decision is the material to be used for paneling.

The greenhouse roof should be strong enough to withstand extreme temperatures and strong impact.

In other words, the roof needs to be strong and durable.

Hence, polycarbonate qualifies as a good material for the panels.

Polycarbonate is a lightweight and high-performance plastic with carbonate groups in its chemical structure.

The polycarbonate sheets have several advantages and are available in different types.

If you have any questions about polycarbonate greenhouse panels, you have come to the right place.

This guide will answer all of your questions about polycarbonate greenhouse panels.

Why Is Polycarbonate Good For Greenhouse Panels?

Polycarbonate is the most frequently used material for making greenhouse panels.

Various qualities make polycarbonate better than other alternatives.

Some benefits of polycarbonate are:

· Impact resistant and strong

Polycarbonate is a long-lasting material that has a high resistance to impact.

This makes it a good material for you to use for rooftops that can suffer impact due to hail, snow, or even stones.

It is far more durable than glass and will not shatter upon impact.

You will find this provides a sturdy structure for the greenhouse that is resistant to difficult weather conditions.

· Fire resistant

Resistance to flames is an important factor in selecting the material due to safety concerns.

The flammability of polycarbonate is quite low so your rooftops and windows will not catch fire easily.

· Light transmission

Polycarbonate is transparent and provides a high light transmission so you can see through it clearly.

The requirement for the light may vary between seasons and geographies.

If you have windows, you may prefer to use a material with high light transmission and then cover it to reduce glare if needed.

Polycarbonate provides up to 90% light transmission.

· Insulation

This is the most important quality of a greenhouse.

Insulation refers to the quality of retaining heat within the area.

The heat retention in a greenhouse allows the plants to grow and nurture at their optimal temperature.

Higher heat retention also increases energy efficiency.

Polycarbonate has a high insulation level, especially corrugated and multiwall polycarbonate sheets.

Hence, you can use them for greenhouses.

What Are The Types Of Polycarbonate Sheets Used For Greenhouse Panels?

Polycarbonate sheets come in different variants and each has its advantages.

However, some types are more durable and impact-resistant than others.

There are three types of polycarbonate sheets available for greenhouse panels.

These are:

i) Solid and textured polycarbonate sheets

Solid and Textured Polycarbonate Sheets

Solid polycarbonate sheets, also known as flat polycarbonate sheets, are the best alternative to glass.

Moreover, it is 250 times stronger, more durable, and lighter in weight as compared to glass.

The solid polycarbonate is transparent and allows approximately 90% of sunlight to get through.

The material is highly flexible and has good chemical and thermal resistance.

You can also find these sheets available in different textures or tints.

These additions are made so you can control the influx of light into the area to reduce glare.

The material is highly convenient to store, clean, and maintain.

ii) Corrugated polycarbonate sheets

Corrugated Polycarbonate Sheets

Corrugated polycarbonate sheets are stronger than the flat ones.

The sheets have a wave-like structure.

You will find these provide better insulation from heat and cold and also have very high water and chemical resistance.

Moreover, the corrugated structure helps in diffusion and equal distribution of light.

These physical properties make them appropriate for greenhouse panels.

The corrugated polycarbonate sheets are not only limited to greenhouse panels but you can also use them in the roofing of industrial, commercial, and residential areas.

ii)  Multiwall polycarbonate sheets

Multiwall Polycarbonate Sheets

As the name suggests, these sheets consist of multiple layers of polycarbonate walls so the strength and durability of the material increase.

You can find variants ranging from twin walls to five walls structures.

The number of walls is proportionate to thermal and heat resistance of the material.

However, the increase in thermal insulation comes at the cost of light transmission so ensure you pick the thickness with the right amount of insulation and light transmission for you.

These sheets are energy-efficient, highly flexible, and have excellent light transmission.

How Thick Should Polycarbonate Panels Be For A Greenhouse?

Thickness adds to the strength and durability of the material.

Thus, it is advisable not to use a material with a thickness below 5mm.

On the other hand, thickness also increases the overall weight.

A good range of thickness is between 5-10 mm.

You can always use sheets thicker than 10 mm if the panels are strong and sturdy enough to support the weight.

The most common thickness levels for roofing are 10mm, 16mm, and 25mm.

How Long Will The Polycarbonate Greenhouse Panels Last?

Polycarbonate panels are expected to last for many years and you can expect them to last for ten years on average.

This also means that a lower quality material may last only for five years, whereas a premium quality can last up to 20 years.

Hence, choosing a good quality polycarbonate is essential to increase longevity.

Should You Get Clear Polycarbonate Greenhouse Panels Or Green Polycarbonate Greenhouse Panels?

Clear or frosted roofing allows more light into the greenhouse.

The light transmission can go up to 90%.

On the other hand, a green roof absorbs more heat and does not allow as much sunlight into the greenhouse.

Hence, a white translucent surface works the best for a greenhouse because it allows large amounts of light into the greenhouse to promote healthy growth but reduces glare by diffusing light.

How Do You Bond Polycarbonate Greenhouse Panels Together?

You can use the following methods to bond your polycarbonate greenhouse panels together:

i) Screws

Screwing is useful for attaching polycarbonate greenhouse panels to the frame.

Overlapping the sheets and attaching screws will secure both the sheets together.

Use stainless steel to prevent erosion from weather conditions.

However, this method will not seal off the sheets completely.

ii) Adhesives

For tight sealing, you may use adhesives like epoxide glue and silicone sealant.

Epoxide glue, particularly, is useful in bonding the sheets together and avoiding any cracks.

However, silicone sealant comes with a few drawbacks.

If you go ahead with this sealant, make sure to use the neutral cure silicone.

Using adhesives is a cheaper and easier alternative than others.

However, read the manufacturers’ instructions regarding the appropriate adhesives beforehand.

iii) Fusing

Fusing is the best method to keep the strength and optical clarity intact.

To fuse the polycarbonate sheets, all you need is methylene chloride.

First, you need to clean the sheet surface with lukewarm water before applying the solution on the edges.

Once applied, you can match the edges together and stick them.

The sheets need a minimum of 48 hours to dry out completely.

However, you need to be extra cautious while using methylene chloride, as it is a toxic chemical.

Wear protective gear and make sure to be in an adequately ventilated area while handling the solution.

iv) Tape

Another alternative is to use tape for securing the sheets together.

However, it may not show a long-lasting effect and might tear off soon.

You can use the greenhouse repair tape for this purpose.

Before going ahead with bonding the sheets, read the manufacturers’ instructions thoroughly.

Sometimes, the use of certain elements can void the warranty of your polycarbonate greenhouse panels.

Hence, it is important to follow all the guidelines provided by the manufacturer.

How Do You Clean Polycarbonate Greenhouse Panels?

The cleaning procedure is quite simple.

You can follow the manufacturers’ guidelines for the cleaning.

Clean the roof with lukewarm water to get rid of all dust and dirt.

Next, wash it with mild soap water.

Ensure that the cleaning liquid is not very harsh or it will damage the polycarbonate material.

You can use a soft cloth or sponge to clean the surface.

However, take care not to cause scratches on the surface during the process.

Repeat the cleansing with lukewarm water and dry it with a clean cloth.

Do not clean the surface with sharp objects like a steel scrubber or sharp brushes.

Avoid using any harsh solutions for cleaning.

Some cleaning agents like Lysol or Pinesol are not appropriate to use to clean your polycarbonate greenhouse panels.

Don’t use gasoline for cleaning the sheets.

Do not extend the cleaning process more than required.

Rinse the sheets immediately after using the cleaning agent.

Exposure to cleaning agents for a longer period may have adverse effects on the coating.

Do not use boiling water for cleaning. Lukewarm water is enough to get rid of the dirt.

How Can You Install Polycarbonate Greenhouse Panels?

Installing the polycarbonate sheets is a multi-step process.

However, it is much easier to install compared to alternatives like glass.

For a smooth process, follow the steps below:

1. Drill holes on the wooden panel before installing the polycarbonate sheets.

Make sure there is enough room for thermal expansion and contraction of the sheet.

2. Measure the area to be covered and cut the sheets accordingly.

The sheets can be easily cut with a toothed circular saw, or a hand saw.

3. The support for the sheet installation should be steady, preferably timber.

Also, remember to keep at least a 5-degree pitch in the structure to allow running off of rainwater.

Pitch in the roofing

4. Apply purlin tape in areas where the sheets come in contact with the purlin (horizontal support) of the structure.

The main purpose of the tape is to stop the creaking of the sheets due to thermal changes.

5. Attach the sheets to the supporting panel using stainless steel screws.

Ensure that the UV coated side is facing outside.

Also, make sure that you drill the screws efficiently.

6. While using corrugated sheets, ensure that the ribs of the sheets are running in the direction of the slope.

In the case of multiwall sheets, the wall channels should be vertical to form a downward passage.

7. Secure both ends of the roofs with tapes.

You can use blanking and breather tapes to seal the ends of the sheets.

This allows adequate movement of air and the prevention of dust and insects.

Polycarbonate Greenhouse

This video will show you how to install your polycarbonate greenhouse panels effectively.

How Can You Seal The Ends Of A Polycarbonate Greenhouse Panel?

Sealing the ends is essential to prevent water ingress from the roof.

You need to use specific tapes for this purpose.

A blanking tape is used to secure the higher side (ridge) of the roof.

On the other hand, a breather tape is applied to the lower end of the roof.

These tapes are strong, anti-dust, and resistant to UV rays.

You will find the tapes also allow adequate movement of air to prevent condensation.

However, sometimes tapes are not enough to seal the roofing and you need a polycarbonate end closure to do the job.

It makes the ends weatherproof.

You fix the end closure on the lower side of the roof, or the side that is nearer to the gutter.

You attach the end closure using a neutral cure silicone sealant.

The silicone sealant is applied on the underline of the top lip of the end closure.

Then, this side is attached to the ends of the sheet.

This creates a weatherproof bonding.

Can You Stand Or Walk On Polycarbonate Greenhouse Panels?

No, it is advisable not to put a high amount of pressure on the polycarbonate greenhouse panels.

The material is not equipped to support the weight of humans.

Use alternative ways to install or clean the polycarbonate greenhouse panels on your roof that don’t involve you standing directly on top of it.

You can make use of ladders or install wooden planks, especially for the purpose of walking.

How Can You Protect Your Greenhouse From Wind With Polycarbonate Greenhouse Panels?

Strong winds can cause harm to the greenhouse.

If you live in windy locations that endure high-speed winds throughout the year, it is essential to take precautionary measures.

Make sure that the slope of your roof is aligned to the direction of the wind.

This will help the structure withstand strong winds better by being more streamlined.

Make sure that the entire structure is sturdy enough to endure high-speed winds.

This includes the frames and supporting panels of the greenhouse.

All the components should be tightly screwed, with no loose bolts.

Windy areas can build up pressure inside the greenhouse structure.

To avoid this, seal off the edges completely using tape and closures.

Look for any leaks on the edges of glazing that can increase the pressure.

Create a safety valve for the air pressure to escape the structure.

You can also use an exhaust for this purpose.

This will help in getting rid of the pressure and create a vacuum inside the greenhouse.

This will lead to the suction of the sheets towards the frame and reduce rippling.

 Exhaust in Greenhouse

How Can Polycarbonate Greenhouse Panels Protect Plants During Winter?

Firstly, the polycarbonate greenhouse panel does not allow frost to get inside the greenhouse.

This acts as an advantage to the overall structure.

Meanwhile, seal off all the vents and edges properly.

You can use batten tapes specifically on the roofs and edges to secure from harsh winters.

If you have timber frames, flashing is useful to protect the timber from condensation.

The wood is prone to rot and degrade due to moisture.

Hence, flashing will increase the lifespan of the structure.

Wooden panels

How Do You Repair Polycarbonate Greenhouse Panels From Minor Damages?

There might be instances where your polycarbonate greenhouse panels face minor issues due to weather or other conditions.

However, the damage is not big enough to replace the entire roofing.

In such cases, you can use some easy repair tricks. These are as follows:

· Greenhouse repair tape

This tape is a wide polyethylene film with strong adhesive bonding on one side.

It is clear and UV stabilized and is extremely helpful in fixing minor damages to the polycarbonate greenhouse panels.

Whether it is a small hole or minor tears in the panel, this heavy-duty tape will repair it easily.

Patch the tape on both the interior and exterior of the greenhouse panel to increase its strength.

· Sealant

For small holes, you can apply silicone neutral cure sealant to cover them.

You cannot use a sealant to repair large holes.

· Replacing closures

There might be instances of leaks from the polycarbonate greenhouse panels in the roof.

These can be due to a couple of reasons.

The best way to repair the leakages is to replace the closure and edge tapes.

 Greenhouse Repair Tapes

How Much Do Polycarbonate Greenhouse Panels Cost?

Polycarbonate roofing is the cheapest alternative among all others.

The price is much lesser than the glass of the same area.

However, the actual price varies depending on the quality of the material.

We strongly recommend investing in a more expensive material, as it will provide returns for a longer period.

If you use cheaper material, the poorer quality material is prone to breaking more easily and may not perform well.

How Can You Avoid Polycarbonate Greenhouse Panels From Turning Yellow?

Like other plastics, the polycarbonate greenhouse panels get damaged by constant exposure to sunlight and UV rays.

This causes them to turn yellow over a period of time.

Hence, while selecting the polycarbonate material, make sure that it has a coating of UV protection.

This will ensure that the panels do not turn yellow and last longer.

UV coating is always only on one side of the sheet.

Hence, it is of utmost importance for the UV coated side to face outwards.

Check the sticker of the UV side before installation.

Moreover, make sure that the sheet does not have any scratches during installation.

Scratches may remove the UV coating on the sheet.

Can You Retrofit A Glass Greenhouse With Polycarbonate Greenhouse Panels?

Yes, you can retrofit the polycarbonate greenhouse panels in an existing structure.

You might need to make certain modifications to the structure if it does not have adequate facilities.

For instance, if there is no pitch to the roofing structure, you need to include it.

However, in most cases, the polycarbonate greenhouse panel can be retrofitted without any changes.

Can You Paint Your Polycarbonate Greenhouse Panels?

Yes, paints are highly effective in controlling light transmission from the roofing made from polycarbonate greenhouse panels.

Specific paints are made for the purpose of covering the roof.

You need to follow the correct procedure to avoid flaking.

As polycarbonate is non-porous, the material might need some pre-conditioning before applying paint.

This video shows you how to paint your polycarbonate greenhouse panels with solar reflective paint.

https://youtu.be/oJ3lMJ7EqwI”>

What Kind Of Paints Can You Use While Painting The Roofing Made From Polycarbonate Greenhouse Panels?

The paint that you apply on the polycarbonate roofing of the greenhouse should be resistant to UV rays and harsh weather conditions.

Moreover, the paint should control the light transmission and heat as per your needs, and not stop it altogether as that will affect the growth of the plants.

For this purpose, you will find specific paints known as “greenhouse shade paints” useful.

Shade paints are the most cost-effective and easy way to control light transmission.

The paint also helps in controlling heat.

You can dilute the paint per your requirements.

For instance, one coat of shade paint can reduce heat transmission by approximately 15% and light by 7%.

Moreover, the shade paint does not get affected during rainy seasons, unlike other ways of shading.

The removal procedure of the paint is also quite simple and painless.

All you need to do is apply the paint removal mixture, preferably from the same brand as your paint.

The next step is to wash off the mixture with the help of a garden hose.

Make sure you read the manufacturers’ instructions before application.

It is recommended that you use the shade paint in the spring season, right before the onset of summers.

You can then wash it off in the fall season.

This will ensure appropriate sunlight round the year.

Shade Paint

Does The Change In Temperature Affect The Polycarbonate Greenhouse Panels?

Yes, the temperature change affects the polycarbonate panels.

The material tends to expand in high temperature and contract in lower temperatures.

These changes can take place multiple times within a day.

The highest amounts of expansion and contraction take place during the spring and fall seasons.

Therefore, it is essential to include necessary adjustments for the changes.

You should oversize the screw-holes to make room for temperature changes.

Can You Curve The Polycarbonate Greenhouse Panels In A Greenhouse?

Yes, polycarbonate sheets are flexible enough to form arcs for better fitting.

These are cold-bent during the installation process.

However, the radius of the arc depends on the degree of flexibility of the material.

Check with your manufacturer to know more about the radius that you can bend your polycarbonate greenhouse panel to.
