This means that a tpo roof is as uv resistant and as heat resistant as epdm and as heat weldable.
Cold deck roof advantages.
Well a cold roof is created by laying insulation between the rafters.
Traditionally flat roofs simply consisted of a structural timber deck with a waterproof covering directly applied to the top of the deck.
This design dates back many years and flat roof insulation was somewhat of an afterthought with this type of roof.
Polycarbonate is also very lightweight and capable of withstanding extreme temperatures either hot or cold.
The 18mm roof grade deck is then fixed on top of the rafters leaving suitable air flow between the insulation and the deck.
Warm flat roofs make it easier to eliminate cold bridging allows heat to be conserved with no requirement for roof void ventilation allows moisture to escape which prevents.
Tpo is touted to have the benefits of two of its direct competitors epdm and pvc roofs but without the drawbacks and extra costs.
It is ideal for other structures such as decks garages patios sheds.
Where a cold flat roof does incorporate insulation this is.
Less thermally efficient than a warm roof construction cold roof construction remains the most common form of construction for existing flat roofs.
This allows air to circulate.
Due to these qualities it makes for an effective roofing material for many applications.
The simplicity of a warm flat roof makes it one of the most popular designs providing an effective and easy way of.
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.
A cold deck is constructed as follows.
If you are looking to install a single ply roofing membrane that will be energy efficient and are evaluating your options consider tpo thermoplastic olefin roofing.
Which makes sense as this space is otherwise empty and so it s a simple low impact way to insulate a roof.
Traditional cold deck flat roof.
The thermal efficiency isn t as good as with warm roof insulation.
While polycarbonate roofing may not be the best option for an entire house.
A cold flat roof insulation requires more work taking off old boards and replacing them and the roof surface.
A warm deck roof is much easier to install offers great thermal performance but adds height to the flat roof.
A cold roof can be cheaper as ridged warm roof insulation tends to be more expensive a warm roof is sometimes the only option when it is difficult to get the required.
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.
