Generally, Twinwall and Multiwall polycarbonate have the same properties but they offer different levels of insulation. The easiest way to remember this concept is that the more layers a sheet has, thereby more thickness, the more insulation is provided. If a structure requires heat containment or is a place of residence then Multiwall is going to be the more suitable choice as it provides more insulation.
Traditionally, 4mm and 6mm Twinwall are suitable enough for greenhouses, cold frames and sheds. They are easy to maneuver and adhere to even fairly unusual fits due to their lightweight structure and curving capacity.
10mm polycarbonate sheeting is appropriate for carports, pergolas and sheds as well. Although a thinner polycarbonate can be used for sheds, it is completely down to the user about how much insulation they require or how strong they believe their structure needs to be, or how rigid.
The thicker polycarbonate sheets such as 25mm, 32mm and 35mm Multiwall sheeting are going to provide the highest level of insulation and are therefore more than adequate to be used as the roof of a conservatory. Its translucent quality enables light to filter through, allowing bright and ambient spaces to be created that maintain their warmth throughout the year.
Other uses for polycarbonate sheeting include, but are not limited to:
Vertical glazing
Sporting goods
Bus shelters
Which polycarbonate roofing sheets are best?
Coming to a decision about the best choice between Twinwall and Multiwall is always going to depend on the requirements of your project as well as the time, methods and cost you have to install it.
For example, if a customer wishes for a room with more light then a polycarbonate sheet with a higher level of light transmission is going to be the more favourable and appropriate option e.g. a greenhouse.
