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 the sun, structural support and vital insulation.

However, a well designed roof can also fulfil a number of other 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 insulation.
