BriggsAmasco has been involved in the installation of green roof systems for a number of years in the UK. Training in both the concept and application of these systems, has been given to key personnel in every branch.
Benefits of a Green Roof
- Environmental and sustainability enhancement, combating global warming.
- Rainwater attenuation in heavy rain conditions.
- Long-term economic benefit of installing a green roof.
- Green roofs cool the surrounding air in summer creating a beneficial micro-climate.
- In city centres, green roofs are visually pleasing creating a softer landscape.
- Increase of roof life.
- Reduction of noise and dust levels.
- Providing new habitats for wildlife and increasing bio-diversity.
Types of Green Roofs
Generally, green roofs are in one of two types.
1. Intensive Green Roof
Essentially, this is a garden roof. It requires a greater depth of soil to nurture a wide variety of plants which may be used. It requires regular maintenance as with a normal garden, and has a saturated load in the region of 400kg/m2.
2. Extensive Green Roof
This is a lightweight sedum planted type of roof, giving a wild grass appearance. It requires only low maintenance and has a saturated load in the region of 90kg/m2.
BriggsAmasco won the Active Roofing Systems category, in the 2008 Scottish NFRC awards, for a Green Roofing Project at the Aulton Community Centre in Seaton, Aberdeen.
The project for Aberdeen City Council, pictured below, comprises a series of three elegantly curved roofs spanning the Aulton Community Centre at Seaton. Covering some 1,000sq.m, the sedum clad roofs, which extend from eight to 14m in length, start from just two degrees increasing to a 32 degree slope.
The complete Index system incorporates 170mm ofinsulation, 5mm of Proteaduo (the BBA approved APP/SBS composite membrane), Defend Antiroot (which conforms to the FLL Standard) and Flexter Mineral on all exposed details. The Index Insta sedum blanket was delivered to site cut to size.
The Conan Doyle Medical Centre in Glasgow, pictured at the side, was also a finalist in the 2008 NFRC green roofs category
