Polycarbonate Roof Sheeting is a versatile material used extensively for roof light gazing. It is highly resistant to impact, transmits high light levels, is relatively easy to use, and has a good fire rating. Polycarbonate is one of the newer plastics to be used in the construction industry worldwide.
Polycarbonate Roof Sheeting comes in two forms, each with its particular characteristics and properties:
Polycarbonate roof sheets offer high durability. Sometimes referred to as “plastic steel”, it’s virtually unbreakable with high light transmission and excellent weather resistance. It is ideal for greenhouse coverings and skylight applications. Professionals favour polycarbonate sheeting for non-corrosive industrial structural roofing and side cladding. However, homeowners tend to choose polycarbonate roof sheeting for many DIY projects. Polycarbonate sheeting is available in a wide variety of colours and profiles.
STANDARD SIZES ARE AVAILABLE HOWEVER LENGTHS UP TO 12.8m CAN BE ORDERED.
Polycarbonate Colours: Light = Heat
As a general rule, the more light that comes through the sheet, the hotter it will feel under the sheet. There are a few exceptions to this rule, and these tend to be the premium ranges in the different brands of polycarbonate sheeting. Choose sheets types to help skew the amount of light available without letting as much heat through. They can reflect more of the heat. In warmer areas of South Africa – we generally caution people against using clear sheeting. In cooler parts of South Africa, clear can be a great option.
Other environmental factors should also play a part in your decision making:
Explaining the Numbers
Solar Heat Gain Coefficient or SHGC is a number that describes how much heat passes through a material. It is the amount of solar radiation that passes through the material and heat absorbed and released inward. It is expressed as a number between 0 and 1 – the lower the number, the less the heat. You would want a product with a low SHGC number in a hot area.
U-value is the measure of how well heat is transferred through a material. The lower the U-value, the more insulation the material offers – the better it is at keeping the heat or cold out. You will notice that this is mainly affected by the material and how thick the material is.
In summary, you’re sure to find the perfect colour to suit your needs as there are plenty of colour options when looking at polycarbonate sheets. To choose the colour that will give you the right heat/light scenario for your space, be sure to consider what you use the area for when you use it and specific environmental factors when deciding on what colour is going to best suit you.
