Guidelines To Help You Install Polycarbonate Roofing The Right Way

Guidelines-To-Help-You-Install-Polycarbonate-Roofing-The-Right-WayAlthough sunlight is a source of vitamin D and is very necessary for the growth of humans as well as plants but, too much of sunlight can be bad. Just like too much exposure to the sun’s UV rays can cause skin cancer, sunburn and premature ageing, it affects plastics, fabrics and wood adversely too. This is why if you are looking for perfect roofing that can provide enough sunlight for your plants within your greenhouse yet protect them from the harmful UV radiations, then polycarbonate sheets are the best option. Polycarbonate has several benefits over other materials like being durable, strong, flexible, light-weight and easy to install. However, even though they provide ease of installation, there are many factors to be considered while installing polycarbonate greenhouse panels for your roof.

The right side

Polycarbonate provides UV protection but, it does so only on one side of the sheet. So before installing, you need to find out which side of the sheet provides protection. If you install the wrong side, you will not be able to reap the benefits, which will result in withering and discolouration. Therefore, the side of the sheet that provides UV protection should face the sun. Look for a sticker that may tell you the right side. Avoid scratching the surface to check or you may damage the protection layer.

Cutting

Polycarbonate sheets are very easy to cut. So, you must avoid high-speed cut-off wheels because they will result in melting the sheets. Instead, you must use sharp scissors, jig saws or circular saws that are fitted with fine-toothed blades to do the job for you.

Keep in mind the temperature

Temperature changes through the day and throughout the year, which results in expansion and contraction of the sheets. Thus, you need to provide allowances for this thermal movement from the very beginning. If you fail to do so, the resistance to adjust as per the temperature will cause the sheets to buckle.

Drilling

You must make sure to pre-drill screw holes before fixing the sheets. Moreover, you must slightly oversize the holes in order to make room for the thermal adjustments. Likewise, even the caps and flashings should be pre-drilled so that the roofing sheets underneath can shift as per the temperature change demands.

Cleaning

After installing or whenever you want to clean the sheets, you must do so only with soapy water and a soft brush. Abrasive tools and harsh chemicals will only damage your roof. Also, if you see any kind of bird droppings on your roof, clean it immediately to prevent staining.

Other considerations

Other than the above mentioned important considerations, there is more that you must remember.

  • Install sheets at a minimum pitch of 5 degrees so that it allows rainwater to run off towards the gutter and prevents moisture from collecting on your roof.
  • Consider the wind direction while installing and make sure you lay the sheets in the correct orientation, or the wind will tear away your sheets.
  • Use purlin tape on all the surfaces that come in contact with timber. Also, don’t use sheets with purlin spacing wider than recommended, or the sheets may sag and water will collect in sagging areas.
