Should you Create a Warm or Cold Roof

Should you Create a Warm of Cold roof?
A question which is asked by many – should I have a warm roof or a cold roof?
You can create a warm roof, or a cold roof, simply by applying the layers of the roof in a different order. Namely the insulation layers.
When installing a cold roof, the insulation is applied between the rafters. A 50mm gap is left between the top of the insulation, and the roof deck above. This allows air to circulate. However, this also allows cold air to enter.
When installing a warm roof, the insulation is applied on top of the existing roof surface. This process offers a greater level of thermal insulation, for your whole property. It’s also simple to install, as long as your existing roof deck is in good condition.

Case Study – Cotton Gardens
Cotton Gardens was specifically developed to make use of the historic Union Mill building in Bolton, developing 105 one- and two-bedroom apartments.
We installed an advanced Alkorplan roofing system by Alumasc.
We began the project with the installation of an Air and Vapour Control Layer (AVCL) using the Alumasc Polyethylene Membrane.
Following the AVCL layer, we then installed the waterproof membrane to complete the roofing system. For this, the Alkorplan by Alumasc Reinforced Membrane was selected.
The project went well and was completed to a high standard, with everyone involved happy with the work. The roof achieved the requirements for a 20-year guarantee.
