Green Building Roof Insulation

R value measures how well insulation works.

Green building roof insulation.

Department of energy polystyrene insulation comes in rigid foam boards that make it easy to insulate any part of a building. Yet polystyrene is a fabulous insulator with r values that range from r 3 8 to r 4 4 per inch of thickness and so it s considered green because it helps save so much energy source. Heat flows from hot to cold. Energy and cost efficient insulation for green building fox blocks insulating concrete form wall systems provide an extremely energy efficient building envelope offering superior strength sound air quality and well insulated walls.

In fact good long term insulation performance is needed to correctly design a building s heating and air conditioning systems. In fact it s a form of plastic. It helps control the flow of air and moisture into the home and also insulates the home from extremes in temperatures. Insulation is designed to reduce energy costs so in that sense any insulation could technically be considered green.

Roofing is a very important consideration in home building. Sustainable building starts with reducing the heating and cooling loads of the home as much as possible and insulation is the key to energy conservation a cornerstone of green building. Icf s are proven energy. But a new wave of eco friendly insulation options has arrived and they re more than worth exploring for your green building or remodeling project.

An essential attribute for sustainable building products especially insulation is the ability to function properly over its useful life without physical property performance degradation. The only reason i went with this type of roof insulation is because of height limits ceiling height on the inside and house height on the outside. This may not seem much but for the human ear an 10 db reduction in noise levels is 50 quieter. If we measure the rate at which heat flows through a building material or building assembly for example a wall or a roof we can calculate a number the r value to indicate its insulating ability.

After all insulation isn t exactly designed with aesthetics in mind. It was fairly expensive the other sections of the roof which are a combination of. It can t be stopped but it can be slowed. Green roofs reduce sound resonance by 3 db and provide sound insulation of up to 8 db.

The complete source for building designing and remodeling green homes. The degree of sound insulation will depend on the thickness of the green roof structure.
