As the newest member of Jablite’s roof insulation team, I have been compiling useful information about various roofs and the insulation options available. 

Here is a list I put together about inverted roofs, my colleagues suggested that I should  blog it, in the hope that others might just find it a handy list too - so here it is -  if you would like to know more, please get in touch!

USEFUL FACTS ABOUT INVERTED ROOFS AND INSULATION

1. Inverted roofs are a good option when more traffic than usual is expected on the roof. This might be for plant maintenance   or to provide an area for relaxation like a roof garden.
2. The structure of an inverted roof is opposite to the norm. The weatherproof membrane is laid first, followed by the insulation, a filter medium and lastly the ballast (typically gravel or paving slabs).
3. This roof structure protects the weatherproof membrane from being damaged when the roof is being used.
4. An inverted roof is sometimes called a ’protected membrane roof’ because the membrane is protected by the layer of insulation.
5. Up to a quarter of a building’s heat can be lost through a poorly insulated roof; so the roof insulation is a vital part of the building’s energy management planning and can help to reduce CRC (Carbon Reduction Commitment) liability.
6. The insulation on an inverted roof is not just an insulator; it also protects the membrane from the elements. That means the insulation specified must be able to withstand this exposure and continue to provide a good insulating performance.
7. An inverted roof will typically last much longer than a traditional flat roof.
