Green Roof Insulation Materials

Green roof insulation materials.

In addition to thermal insulation a green roof also has a sound insulating effect. Green roof solutions root barriers are the dividing line between the green roof assembly and the roofing membrane for certain roofing waterproofing systems. A green roof is in ecological terms a great and simple thing to do. Green roofs have a thin covering of soil and live plants growing on them which provide shade insulation and evaporative cooling that reduces temperatures on the roof surface and in the building.

This is most noticeable in intensive green roofs since there is a thicker and more consistent layer of soil which provides a higher insulating value. For one thing it can be rolled into batts. Fire resistant treated insulation is made with 85 recycled material that meets a class 1 fire rating to protect your home and give you more time to evacuate. Sound waves are absorbed and reflected.

Cotton insulation is similar to fiberglass insulation in several ways. The combination of substrate plants and the embedded air in the green roof system provide good sound insulation. This flexible tear and puncture resistant material keeps roots from penetrating the roofing membrane and causing leaks. Their buildzoom score of 102 ranks in the top 11 of 336 931 california licensed contractors.

Used over a whole roof a green roof will be the single overriding design influence on the house as well as impacting on the construction right down to the foundations. At first glance this might not sound like a green option but polystyrene is considered to be green because it helps you save an enormous amount of energy. Green roofs can help reduce energy costs for a building by acting as another layer of insulation between the inside and outside of the roof. Well some of that material actually gets recycled into insulation.

Cotton is a natural and renewable resource which makes the plant one of the greenest insulation products on the planet. The substrate blocks the lower frequencies while the plants absorb the higher frequencies. Greenfiber blow in cellulose insulation fills gaps and voids to create an energy saving thermal blanket that can lower heating and cooling costs by 25 and reduce sound power by 60. But the manufacturing process materials and toxicity are other highly important factors to consider.
