Developers, investors and builders are rushing to keep pace with the surging demand for multi-living housing, especially with rental apartments.  A large segment of the renting population want to spend less time commuting and more time creating a balance between career and lifestyle.  Demand in apartment living has pushed the design of common areas on the roof. Tenants and owners don’t want concrete roofs they want their rooftop turned into gardens, decks and terraces created with the use of Green roofs.

Green Roofs have many benefits but for maximum benefit to the building roof area insulation should be an essential component.

Whether under pavers, decking or green roof areas the high load bearing capabilities and thermal resistant benefits of Foamular Extruded Polystyrene Insulation will lower long term energy demand.

Foamular Extruded Polystyrene provides no nutritional value to plants, animals or bacteria, so it is not degraded by their presence. It also has very low water absorption potential, and can easily function in the presence of moist growing medium and water runoff.

Foamular Extruded Polystyrene's high compressive strengths means it is not affected by continuous pressure from foot traffic, growing medium or other loads. Austech has a range of compressive strengths available that can deal with heavy loads, including vehicular traffic.

In a way, it’s almost no contest. When compared to brick, wood, stone, stucco, and metal cladding on the basis of initial cost, maintenance costs, appearance, durability and value, vinyl cladding is clearly superior. Vinyl Cladding never needs painting or staining. It doesn’t chip, peel, dent or rot, so you can forget costly repairs. Just rinse occasionally with a garden hose.

The foam on the back of the vinyl cladding boards can come in 20mm and 30mm. The option of foil is also available, for that little bit of extra insulation.
