Not many construction products can deliver something valuable that is entirely free.  Maximising the benefit of this natural resource, in conjunction with automated lighting controls, can save more energy in a building now that increased levels of insulation are delivering significantly reduced returns.

During the colder months, rooflights can still contribute to the heating of a building through solar gains. The use of a rooflight with good levels of light transmission and improved thermal performance to reduce heat loss can deliver significant savings.
