Roofing systems have a key role to play in maximising the
environmental efficiency of any building. A roof provides an
interface with the external environment and performs a variety of
basic functions, including shelter from the elements, shade from

requirements that contribute to a more sustainable building:
- Allowing in daylight through rooflights and sun tunnels.
- Collecting rainwater for domestic use.
- Collecting the sun's energy for power and heat.
- Providing ventilation and heat recovery.
- The retention of heat through the use of insulation.
Jewson offers a range of solutions that perform many of these
requirements, and elsewhere in this guide we discuss many
compatible products and systems including photovoltaics, solar
thermal systems, rainwater harvesting, heat recovery and
