Inverted Green Roof

As the inventor of the inverted roof dow s styrofoam brand xps insulation has been the top choice for green roof assemblies for over 40 years to resist moisture and provide long term.

Inverted green roof.

The example above shows an extensive green roof build up with floradrain fd 25 e allowing for diffusion however most of the zinco drainage elements are vapour permeable so many other varieties of zinco build ups can be realised on inverted roofs. The ideal assembly for driveways on inverted roofs. High performance roof insulation suitable for use in a range of inverted roofs including green roofs and protected membrane flat roofs. The system solution shown relates to the green roof build up in particular.

Compatible with green roof systems resistant to the passage of water vapour easy to handle and install ideal for new build and refurbishment non deleterious material manufactured with a blowing agent that has zero odp and low gwp kingspan greenguard inverted roofs insulation for protected membrane flat roofs and green roofs insulation. Choosing a green roof or blue roof assembly capable of withstanding water saturated vegetation without absorbing it is critical to the integrity of the roof. Bre investigated a large building with an inverted roof that was suffering from persistent leaks with water dripping from the underside of the roof and on to suspended ceiling tiles. Green roof solar.

The green guide informs breeam ratings and here the biggest additional contribution will be the iso 14001 certification for the manufacture of the waterproofing and the insulation. In contrast to conventional flat roof build ups the inverted roof is characterised by a reverse arrangement of layers. An inverted roof also referred to as a protected membrane or upside down roof is form of flat roof in which the waterproofing layer is beneath the thermal insulation rather than above it. Inverted roof designing buildings wiki share your construction industry knowledge.

As a result the waterproofing is perfectly protected against mechanical damage. Create a recreational park or plaza on your building s inverted roof including driveways and parking areas. The main way that an inverted roof differs to a ballasted is that the insulation sits on top of the waterproofing but in both scenarios the waterproofing is essentially never exposed. The waterproofing is applied directly onto the load bearing roof structure.

Most of the inverted roof insulation boards have an a or a rating but as an inverted roof is usually on a concrete deck the overall rating will be c or d. When the insulation was removed from the worst affected area a large number of water filled blisters were found in the waterproof membrane figure 1.
