The Importance of Shade Cloths

There are many factors involved in greenhouse gardening. And we all know that to grow different plants and flowers the conditions need to be just right. So climate control and ventilation are very important. Greenhouses can get very hot in certain areas around the country. So for that extra protection we offer shade cloths.

But why? Well, in humid areas misting and fogging may not be adequate enough in thosehot summer months. And excess moisture build up can become a problem.

There are many different ways to “shade” your greenhouse. Spray on and liquid options are available. As well as woven polyester or even aluminum varieties. Shade cloths can be found in varying densities or degrees of shade from approximately 5% to 95%.

Sunglo’s Shade Cloth Material

Sunglo offers a 73% gradient polypropylene cloth with double sewn reinforced hems and brass grommets for easy anchoring. Polypropylene is a thermoplastic polymer and it is used in a variety of products around the world.

 Polypropylene is normally colored using carbon black. It is tough stuff but still flexible and it has good resistance to fatigue. It is suseptable to UV damage from sunlight exposure but our shade cloths are coated with a UV absorbing additive and carbon black also has some “SPF” properties to it.

Shade cloths can be the difference between beautiful plants or burnt plants! Don’t leave your plants to risk, shade cloths are inexpensive and will last you through the years keeping your plants safe and happy!

To attach Sunglo’s shade cloth to your greenhouse, use some bungee cord or rope to thread through the grommets and secure them to some loop posts that are anchored to the ground or base. Lean-to models: For convenience try to set up the loop posts so you can easily roll the shade cloth up or down.

Acrylic vs. Poly-carbonate Greenhouses

I am often asked why we use acrylic for our greenhouses. With all the poly-carbonate models available today I find this to be a very valid question. Poly-carbonate has become cheaper and more readily available over the years, and I envy the ease of buying the material in sheets and simply cutting it to fit. However, I must only reflect on the ingenuity of our patented Therma-Truss design to remember that this is one attribute that truly sets a Sunglo Greenhouse apart from all the rest.
Dual Pane Acrylic Cross SectionThis dual pane design incorporates a smooth outer layer of UV stabilized impact resistant acrylic and a custom corrugated acrylic inner layer . Together they form 1.5 inches of dead air space and result in an impressively high insulation factor of R3.1 which is similar to a dual pane window. To achieve this with poly-carbonate would require such a triple thickness that light transmittal would be greatly diminished to 70%, 60% or even less. A Sunglo has 92% of the light come in. Light is your friend in a greenhouse. In fact, for all its insulating value the radiation transmittal rate is nearly the same as that of glass. Also, the UV stabilized and impact resistance treatment our material receives gives it an expected lifespan of 15 to 25 years without the yellowing so common of poly-carbonate. We guarantee the panels to remain clear for 12 years, even in the Arizona sun.  That gives our customers 8 to 15 more years to enjoy owning a Sunglo greenhouse without having to replace the glazing material. And even at that time you may only need to replace the flat roof outer panels. The corrugated inner panels are protected from UV by the outer panels and after a careful wash can still look great. In Seattle we have washed and re-used corrugated inner panels as old as 36 years.

We carry replacement panels for every greenhouse we have ever sold which are easily reinstalled into the durable framework. What all this means is that a Sunglo Greenhouse will create a better growing environment with less energy costs for many, many years.
For these reasons we continue to stand by our acrylic design as we have for over 40 years now, and I applaud the two Boeing engineers who originally conceived and patented the Therma-Truss system. Thanks for reading and please contact us if you have any questions about choosing the proper glazing material for your next greenhouse.
