Loft Conversion Warm Or Cold Roof

You should leave the space under the roof tiles free from insulation to give adequate ventilation so that you don t get condensation or water coming through the tiles.

Loft conversion warm or cold roof.

The room is great however it gets so cold in the autumn to winter and even with heating on it does not help. This construction method is called a cold roof as the rafters are not part of the warm insulated part of the structure. Pitched roofs are generally easier to insulate as insulation can be fitted under or over rafters during new installations refurbishments and loft conversions depending on your requirements. Warm loft insulation is used on pitched roofs where you are using the loft space as a room or for storage.

It was done 7 years ago. Anything underneath the warm roof insulation is now part of the fabric of the building the same as the plywood or ceiling below it. For condensation to form it would need cold too meet hot air but now its all hot air inside the building until the top of the warm roof insulation. Is there anything we could to improve the heat such as foam in the roof etc.

However there are several practical ways you can keep your loft conversion cool this summer. But it leaves the loft subject to temperature fluctuations and condensation. If we learnt anything from science class it s that heat naturally rises which can mean that during the summer months our attic conversions can become exceptionally warm and stuffy. When adding the insulation to between the rafters there should be a 50 mm ventilation gap above the insulation between the insulation and the sarking felt.

A cold loft would be unsuitable if you plan on storing materials sensitive to either or if you intend to use the space for activities. A warm loft is suitable for converting into an office an extra bedroom the gym you plan to use the playroom for when the kids get too noisy and any other reason you can think of to live in it. The object being to design out the possibility of warm moisture laden air coming into contact with a cold surface and condensing. This means that some heat can get into the loft and regulate its temperature but is prevented from escaping through the roof.

A warm loft is where you insulate immediately under the roof which means your loft space is warm as well. To create a warm loft on the other hand the insulation is divided between the loft floor and the underside of the roof. Because it is a warm room it will provide insulation needed to keep it either warm or cool. Warm roof construction requires that the entire roof construction is encapsulated within the insulation envelope of the building to be kept warm.

We bought our house with a loft conversion already done. The ceilings are plasterboarded with no access to the roof. The insulation should be level with the bottom of the rafters.
