Internal shading options
• Curtains, when drawn, significantly reduce light but reduce heat gain by only a small amount. They also reduce ventilation and block views.
• Venetian blinds and vertical blinds can be used to adjust the amount of incoming light while retaining views but they reduce heat gain by only a small amount.
• Roller blinds and other types of window blinds reduce the light admitted but also reduce the heat gain by only a small amount. They may also reduce ventilation and block views but some types of blinds provide two adjustments: one setting provides partial light block
out, the other setting provides full block out. Blinds may be motorised for high level window or roof lights. They can be made from a range of sun filter fabrics to suit the desired level of light, view and shading.
