The polycarbonate sheets are currently being used instead of other materials such as polyethylene membrane, toughened glass and glass. This has been due to the desirable features they possess such as lightweight, high impact strength, UV protection and better aesthetic value. Furthermore, frosted and embossed polycarbonate sheets are mainly used for decoration purposes. There are quite a number of polycarbonate sheet applications where both hollow and solid sheets are used.

Normally, the main difference between these two types of carbonate sheets depend on the level of light transmission and the impact strength. For instance, in polycarbonate sheet applications where strength is of a priority, using a solid sheet becomes the best alternative. On the other hand, for thermal insulation applications; the hollow polycarbonates are superior.

Polycarbonates are used to make the following key items:

Electrical and electronics; this material is used to make quite a number of electrical and electronics equipment. Some of the most common parts include the switching relays, sensor parts, LCD sections, connectors, cell phones and computers just to mention a few. This is due to its light weight and high impact strength. The fact that hollow polycarbonates are perfect thermal insulators makes them to be a perfect choice in most electrical and electronic industry. Closely related to this is the optical industry, where they are used to make optical discs which are some of the most common storage medium. These include the CD, CD-ROM, DVD etc.

The polycarbonate sheets have gained popularity in a number of applications such as greenhouse glazing due to the wide range of advantages as they are associated with. Its weight, UV resistance properties, flexibility and high impact strength are some of the outstanding properties of the materials.

How to distinguish polycarbonate sheet’s quality has been one of the most challenging processes. In any application, the polycarbonate sheet’s quality can be determined based on R value, shading coefficient, solar reflection, U value, light transmission and solar heat gain coefficient. Of course, this may be very technical for an ordinary shopper- a reason why you should acquire these items from a reputable dealer whose products come with a warranty.

polycarbonate sheet quality checking

Below are simple procedures which can help you to distinguish polycarbonate sheet’s quality:

  1. The quality of any polycarbonate sheet will be determined by the type of material which has been used in the manufacturing process. Normally, manufacturers produce polycarbonate sheets using two main types of materials; new raw materials and recycled materials. A polycarbonate sheet which has been manufactured from recycled material will have a yellow surface when viewed under sunshine. Those that have been manufactured from new raw materials will be clear and bright. This is the first test you should conduct when you are planning to buy polycarbonate materials.
  2. Bending test; you can conduct a bending test on the polycarbonate materials. You can cut a small piece of the sheet and bend it more than 10 times. Normally, the low quality materials can only bend about 2 to 3 times after which they will break. However, high quality polycarbonate sheets can bend more than 15 times.
  3. Examining the cross section of the sheet and the weight. You should ensure that the sheet stub is vertical and the thickness is uniform. Similarly, it should not have a lumping weight.
  4. Light transmission; a quality polycarbonate sheet should transmit about 75% of light with the same and thickness. Those that transmit light below 75% are considered to of poor quality.

These are some of the most basic tests which can be conducted to distinguish polycarbonate sheet’s quality. There are quite a number of tests which can be conducted which may require specialized technology. An example of such a test is the use of ZEISS microscope, which is used by most polycarbonate sheet manufacturers to determine the UV thickness. Remember, UV coating is an essential part of these materials since they resist strong sunlight thereby, preventing the yellowing of the sheet. The burn test can also be used to determine the quality of the carbonate sheet. When you burn polycarbonates and extinguish them; they should produce a faint, sweet aromatic ester. Moreover, the color of the flame should be orange.

In most cases, the advanced test to determine polycarbonates sheet’s quality is conducted during the manufacturing process in industries. This is because the test procedures are both time consuming and expensive. It is important that you go for those products which have been certified by the regulatory authorities. You should deal with only those companies have been ISO certified.

How should you clean polycarbonate sheets?

Cleaning a polycarbonate sheet is such a simple process which involves the following simple steps:

Choosing the types of cleaners; you must use only the recommended cleaners. All cleaning agents are tested in laboratories to ensure that they actually compatible with carbonate sheets. Some products which are incompatible with sheets under laboratory conditions include: Lysol, pinesol, butyl cellosolve, isopropanol and formula 409. They should not be used during the cleaning process. On the other hand, there are those cleaning agents such as Freon T.F., joy, Palmolive liquid, top job, VM & P grade naptha, windex with ammonia and brillianize which have been tested and proved to be compatible with polycarbonate materials. Thus, they can be used as cleaning agents.

You must not use either your hand or a dry cloth to clean polycarbonate sheets. This is for the reason that; the two will only rub the dirt off the surface of the polycarbonate material as much as it will be rubbing it off. Thus, it will only be a waste of time and energy.

You must blow the dirt off using water and a soft cloth. For larger areas, you can blow off the dirt using a high-pressure water cleaner of about 100bar. As a rule, before you begin cleaning the entire surface, start by cleaning a smaller section of the polycarbonate material.  You can use a lukewarm water alongside the recommended cleaning agents since it helps to take off stubborn stains without damaging the material.

If there are stains which require scrubbing; you must use a soft cloth to rub the surface. There quite a number of automobile polish which are used to minimize the chances of scratching the surface of the sheets. Finally, you must rinse the polycarbonate material with clean water to remove all residue of the cleaning agents. Furthermore, it is advisable to dry its surface by using a soft cloth since this will prevent water spotting.

how to clean polycarbonate sheet

To clean polycarbonate sheets efficaciously, you need to pay attention to the following key factors:

  1. You must not use any abrasive material since this will only leave the surface of the material with a lot of scratches. This is for the reason that; despite the fact that these materials are known for their high impact-resistance, they are not scratch resistant.
  2. Avoid the use of “harsh” solvents such as hydrochloric acids since they will degrade the surface of the material.
  3. When you are cleaning polycarbonate sheets; you should not clean them at high temperatures or in direct sunlight. This is can lead to discoloration.

As you plan to clean polycarbonate sheets, you should consider all these factors since they form an integral part of any care and maintenance program of polycarbonate materials.

Like most polycarbonate materials, excelite polycarbonate is apparently being used to replace glass in most applications such as in agriculture, public buildings, industries, etc. This has been due to their high impact strength, charming appearance, lightweight, UV protection and better light transmission. In fact, the impact strength of polycarbonate sheets is about 200 times better than that of the ordinary glass. However, it is important to note that polycarbonates lack a very essential property; being scratch resistant. In the recent past, there has been a lot of research going on to develop anti-scratch polycarbonates. So far, this has been achieved by using a hard coating which makes their surface abrasion and UV resistant.

The anti-scratch polycarbonate sheets which have been formulated with hard  coating protects the material against chemical attack and scratching; guarantees optical clarity; protects it against the hostile outdoor weather; becomes graffiti resistance and makes it easier to clean. Normally, these materials are used in areas which experience high traffic. This coating extends its service life; saves you from expensive maintenance procedures and enhance customer usage experience.

For a long time, abrasion resistant coating has been used to protect polycarbonate sheet from scratch besides achieving all the desired qualities. Normally, the term hard coating can be used to refer to abrasion resistant coatings. These coatings come in the form of a very thin film which is optically clear and it can improve the decorative and functional properties. It is advisable to go for those hard coating materials which are durable and flexible.

The choice of a hard coating for any anti-scratch polycarbonate material will depend on the nature of the application. For instance, a polycarbonate sheet which is used in roofing, observe window, indoor partition, sound barrier and outdoor windows should meet the following criteria: an impact strength of about 850J/m; light transmission of between 80% and 90% for different thickness; thermal expansion of 0.065 mm/moC; service temperature of between -40°C and 120°C; tensile strength of >60N/mm2; natural flexibility of about 100N/mm2 and an elongation at break of >100% just to highlight some key features. Choosing the right coating is such a technical thus; it is advisable you seek help from a qualified individual.

Excelite coatingcoating -polycarbonate sheet

Every hard coating which is available in the market has its unique technical data which blends with a specific application. For instance, two products such as SafeCoat 401 and SafeCoat 404 can protect polycarbonate sheet from scratch, however; the degree of this protection will be dictated by the chemical composition of each hard coating material.

The 401 is mainly used in applications where maximum impact resistance is of a priority alongside resistance to abrasion. On the other hand, the 404 is mainly used in applications where the glossy effect is of essence alongside scratch resistance.

You should not assume that by purchasing an anti-scratch polycarbonate sheet, then there will be no need of using the recommended cleaning procedure and detergents; you must adhere to the manufacturers’ guidelines. It is a sure way to optimize its service life.

Most of roofing experts say that UV-coated polycarbonate panels are perfect for the roof because these panels retain heat. These panels diffuse sunlight and reduce the risk of scorching plants, plus available in various thickness to prevent the heat loss during night. Installing such polycarbonate panels can benefit you in multiple ways and able to give you absolute return on the investment.

UV coated

These panels are sturdy and durable, therefore, people prefer them over glass panels. Glass panels are not vulnerable, but also pose serious threat to safety. In an addition, these polycarbonate panels are cost-effective than glass panels. Following are some benefits of installing UV stabilized polycarbonate panels over your greenhouse:

Proper Insulation

Polycarbonate is indeed the most advanced and preferred insulating material with an ability to sustain heat and maintain temperature. Most of the commercial polycarbonate comes with a UV protective coating to avoid panel breakdown and create proper insulation. It is an evident fact that harsh sun light causes serious damage to the surface of roof, and reduces its life.

You will find a variety of such panels, but mainly people prefer twin wall polycarbonate panels. It is because they incorporates thick layers and offer remarkable insulation. If you want more thickness, you can go for triple wall panels, but it is worth mentioning here that thicker panels usually lack the ability to transfer the greatest amount of light. Therefore, it is highly advisable to choose panel based on your actual requirement.

 Why UV-coated polycarbonate panels are superior Than Glass?

Apart from durability, these panels consist of amazing impact strength, which makes them 200 times stronger than glass, and will not breakdown in any condition. So, one biggest advantage with these panels is that they are unbreakable and offer effective insulation without creating any hot spots. Plus, as they have UV coating, there will be no discoloration.

UV protected

Next comes to the weight. Polycarbonate sheets are lighter than glass panels. While building a greenhouse with glass panels, you have to be extra careful as they are breakable and very heavy whereas polycarbonate sheet weighs only one-quarter of the weight of the glass panel. So, you can easily install them without any feature of breakage. While choosing any polycarbonate panel, make it sure that it is UV stabilized polycarbonate, and able to create desirable insulation.

Using multiwall polycarbonate sheet to cover greenhouse is the most appropriate solution in case you live in extremely cold climate. There are multiple reasons to prefer these sheets over others and some of them are as follows:

R- Value: R-value for multiple wall sheets are higher than any other polycarbonate sheet. The R-value represents resistance of insulation to heat flow. As these sheets come with higher R-value , they offer higher insulation.

U-Value: U-value is reciprocal to R-value, and stands as a measure of heat loss rate through any material. If you want your greenhouse to retain heat, buy multiwall polycarbonate panels with lowest U-value, because the lower the U-value, the lesser the heat loss.

Weight: These polycarbonate sheets are generally measures in pounds per square foot. You must not be concern about the weight as they are relatively very light weight, and very easy to install.

Transmission of light: it basically refer to the maximum transmission of light in the visible light region. Many people thought that it is good to have 100% light transmission, which is untrue. A single glass has approximately 90% light transmission whereas a twin wall polycarbonate sheet has 80% transmission. Apparently, multi wall sheet has comparatively less light transmission percentage.

Shading coefficient: Shading coefficient is the total amount of heat that passes through the polycarbonate sheet compared with the heat passes through a single clear glass. Generally, multiwall polycarbonate sheet has a lower shading coefficient.

 Solar Heat Retention: The effectiveness of polycarbonate sheet is measured through solar heat coefficient, which measures how well the material blocks the heat from sunlight. The coefficient is rated between 0 to 1. The multiwall sheets or panels used to have high solar heat retention as compare to single or double panels.

Solar Reflection: Solar reflection is the amount of sunlight that reflects off the sheets. The higher the reflection the cooler the structure will be. The multi wall panels used to have less solar reflection as compared to other sheets.

 The bottom line

Multiwall polycarbonate panels uphold excellent properties to safeguard your property from harsh weathers. The sheets retain heat, and offers terrific insulation to avoid the adverse effects of the extremely cold climate.

Are you looking for professional polycarbonate sheets suppliers for polycarbonate sheet installation? Here, are some helpful information to educate your about these sheets and installation and help you hire the right service provider.

Polycarbonate sheets can be installed on walls and roofs both. You will find these sheets in a variety of colors, sizes and designs to compliment the appearance of your residence. Prices and guarantee vary from sheet to sheet based on their profile and quality, however, corrugate plastic roofing sheet is the most preferred polycarbonate sheet. You can get guarantee of a few months to lifetime, which entirely depends on the quality of the sheet.

Most of the polycarbonate sheet manufactures suggests having a roof pitch fall of 10 degree to handle harsh weather condition successfully. If you install a sheet with less roof pitch, then you would need to install extra shield to safeguard the roof from unfavorable weather. Once you decide the roof pitch, it is the time for cutting.

polycarbonate sheet manufactures

Mostly, these sheets cut down using a fine tooth saw or garden scissors. Always buy high quality sheet because it is easy to cut high quality polycarbonate sheets as compared to substandard one. If you just want to cut one sheet, you can do it using a sick grinder. The only problem here is that if you want to cut down more than on sheet, you need to make fusion and welding of sheets.

Drilling & Fixing of Polycarbonate Sheets

 Once you decide the roof pitch fall and cut the sheets, you need to move onto next step-fixing the sheets. In order to fix these sheets, drill the holes of adequate size i.e. -10mm. Make sure that the hole must be a little larger that the screw’s shaft, at least 2 mm larger in order to provide sufficient space to the screw to expand and contract. If face problem, refer the user guide that comes along with the roofing sheets.

Polycarbonate sheets suppliers can provide you with appropriate screws for polycarbonate roofing panels. Screws with hexagonal heads are highly preferred for fixing. Generally, these sheets are fixed at every fourth corrugation. There are many other accessories that you could use with polycarbonate sheets such as foam eave fillers or ridge/ apron flashing to give it a finished look.
