Inverted roofs because of the need for ballast paving or vegetation inverted roofs typically weigh about 90kg m2 which means the structural load is the.
Inverted roof vs warm roof.
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.
Installing a warm roof can be extremely straight forward and simple to do.
In a warm roof construction the principal thermal insulation layer is located above the structural decking resulting in the structural deck and support structure being at a temperature close to that of the interior of the building.
There are three recognised designs of flat roof construction.
Namely the insulation layers.
The thermal efficiency isn t as good as with warm roof.
Warm roofs a warm roof includes insulation above the structural deck.
Benefits of inverted roofs.
What is a warm roof or a cold roof.
Basically there are two options to choose from when insulating a flat roof.
An inverted roof is quite simply where the waterproofing layer is installed over the structural deck rather than over the insulation.
Warm cold and inverted.
A cold flat roof insulation requires more work taking off old boards and replacing them and the roof surface.
The problem with this kind of flat roof.
Rigid extruded polystyrene insulation has minimal water absorption due to its closed cell structure.
You create a warm roof or a cold roof simply by applying the layers of the roof in a different order.
Inverted roofs or upside down roofs have the insulation laid onto the waterproofing membrane.
When we talk about a warm roof vs a cold roof what we re really talking about is the insulation of the flat roof.
Inverted roof designing buildings wiki share your construction industry knowledge.
In a cold roof the insulation is applied between the rafters but in a warm roof the insulation is applied on top of the existing roof surface.
The breakdown warm roof vs cold roof.
The waterproof covering is placed above the insulation and a vapour control layer is placed below the insulation.
There is normally some ballast to hold the insulation down.
