Need help choosing the right colour of polycarbonate roofing?
Polycarbonate sheets come in a amazing variety of colours and shades. In this post we will outline a few things you may want to consider when making your colour selection.
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. For example, Suntuf has a SolarSmart range and Laserlite have a 3000 range. These types of sheets help to skew the amount of light available without letting as much heat through. They are able to reflect more of the heat.
In warmer areas of Australia like Queensland or Darwin – we generally caution people against using clear sheeting. In cooler parts of Australia clear can be a great option.
Other environmental factors should also play a part in your decision making:
Orientation. Western facing areas may get the hot afternoon sun, for example. This means that if you’re using polycarbonate roofing for a BBQ patio area you may require cooler coloured sheeting.
Roof height. Hot air rises. So the lower the roof the warmer an area may feel. Another factor is how much air flow the area will get. Do you get good breezes coming into the area?
Shading. Trees or buildings may offer shade over your area a certain times of the day. Consider the time of day you expect you will want to use your polycarbonate covered area the most. This may mean that you can afford to go for a colour that lets more light through during the times when its not shaded.
Lighting. Do you require lots of light to a particular part of the house? Polycarbonates can be used in conjunction with Metal roofing to create light over the areas where you need it most. If you are really concerned about heat, have a look at Durashield. Durashield is an alternative to metal roofing. It is made from PVC, so it wont let any light through (like metal), but it is much cooler as it does not radiate heat.
Aesthetics. You may want to match the colour scheme to existing parts of the house. You may wish to create privacy with a more opaque choice. You may be after a striking feature colour. Whatever your vision, you are sure to find great options across our wide range of polycarbonate sheeting products.
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 as well as heat absorbed and released inward. It is expressed as a number between 0 and 1 – the lower the number the less the heat. In a hot area you would want a product with a low SHGC number.
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 mostly effected 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 making a decision on what colour is going to best suit you.
