Fortunately these days there is a better form of insulation available for your flat roof.
Warm deck roof advantages.
Warm deck flat roof.
Landscaping flat roofs offers an effective and practical use of space whilst helping to sustain and replace lost habitats in the process.
Because this design works by conserving heat no ventilation.
By moving the insulation to the outside of the structure the roof deck is effectively brought inside which results in a warm deck hence the name this removes the the possibility of condensation forming on the underside of the deck and eliminates damp.
Contrasted with the cold deck roof this construction has a much lower risk of condensation as the void will be of a comparable temperature to the roof.
The solution warm deck insulation.
Flat roofs construction consists of a top coat and.
The insulation in a warm deck roof is installed immediately below the roof membrane on top of the roof deck usually with a vapour control layer underneath the insulation.
Ease of installation over the top of your existing roof deck as long as it s in good condition.
Knowing the pros and cons such as the price of flat roof repair the roofing material required potential ponding water and roof leaks help make a decision that is best suited for your building.
While flat roofs are not the most glamorous option they have advantages.
This system is called warm deck insulation and eradicates the condensation and venting issues associated with the cold deck system.
The insulation can be adhered mechanically fixed or loose laid.
The vapour control layer is above the decking but below the insulation.
For a warm roof the advantages are.
A cold deck roof is where the insulation is placed between the joists rafters or in between the ceiling joists in the case of a pitch roof.
This allows air to circulate.
However this also allows cold air to enter.
Benefits of inverted roofs.
The insulation is immediately below the waterproofing layer.
The simplicity of a warm flat roof makes it one of the most popular designs providing an effective and easy way of insulating a building.
A cold roof design usually leaves a 50mm gap between the top of the insulation and the roof deck above.
The layer of insulation is essentially placed outside of the roof.
The great benefit of inverted roofs is that the insulation protects the membrane from extremes of weather such as frost uv exposure and the expansion and contraction that comes about from summer winter temperature cycles which can be as much as 80 c on some roofs.
Ventilation is required for these roofs.
Guidance advice on warm cold.
Warm roof designs will make the entire structure of the building warm in order to avoid cold bridging an element of the building that allows heat or energy loss.
