Free Green Roof Kit – a living, extensive sedum roof sample

The Green Roof Kit is back! Architect subscribers to our Roof Design Technical Blog are being offered a free, living Green Roof Trial Kit for their office, to help them demonstrate the beauty and value of an extensive green sedum roof.

Helping you recommend a Green Roof

Green roofs are a brilliant way to add value to the 5th elevation, but many clients don’t have experience of them in the flesh and are sceptical. To help architects demonstrate the value of an extensive green roof to their clients, SIG Design & Technology are offering a free Living Green Roof Trial Kit.

Why use a Green Roof?

A green roof provides a wide range of benefits including:

  • Improved BREEAM credit scores (contributes to 7 credits);
  • Contribution to Sustainable Urban Drainage (SUDS);
  •  Contribution to biodiversity by encouraging wildlife;
  • Improved Energy Efficiency in Warm Roof construction;
  • Improved Sound Insulation by as much as 8dB;
  • Improved life expectancy of the waterproofing membrane; performance of Solar PVs;
  •  Assistance in obtaining Planning Consent.
