When installing a Polycarbonate conservatory or lean-to roof are you considering the U-Value?
U-Values measure the transfer of heat through a structure. The higher a products thermal resistance value the better the insulative performance and the lower the U-Value. There are many brands of Multiwall Polycarbonate in the market, but what one gives you the best protection? Check out the U-Value of your Polycarbonate before purchasing inferior quality sheeting. The thicker the sheet the lower the u-value and better thermal resistance. A lean-to roof should ideally be a minimum of 25mm thick. As well as considering the u-value, light transmission is also a major factor to consider. Clear Polycarbonate Multiwall Sheet will give the best light transmission between 58% – 85% depending on the thickness, bronze between 20% – 35% and Opal 20% – 48%.
You should consider when the space will be occupied, do you need more light, less heat etc. For a sunroom that you want to make use of all year round opt for SOLARSMART Technology, it offers efficient daylighting with high light transmission and heat blocking ability. Our Solar Control sheets block heat better than White Opal or Clear. They are available in Bronze on Opal or Solar Control and offer energy savings and prevents UV damage to Humans, Furniture, and other objects. If you require higher levels of protection, please ask about Sunlite SLT and Sunlight Smart (made to order only).
