To maintain the freshness of his house, the ceiling insulation is essentialThis part of the interior of the house inhibits a large amount of heatOften, the tightness of the walls is not then it is necessary to install air ducts
The importance of isolating the roof
According to specialists of the roofs, the roof stores 30% of the heatIndeed, under the action of a lack of insulation and good air duct, warm air can easily escape out of the houseAs a result, the temperature increases inside the latterIt is thus suggested to invest in loft insulation and the roof in order to have a livable interior and feesThe materials that are normally used are glass wool and rock woolThe advantage of insulating the attic and roof is energy conservationIndeed, in this way there is no need to refresh the interior of his house through a device such as air conditioner
How to insulate the roof?
In order to isolate its roof, the following two points should be well defined: the thermal resistance and spaceDepending on these, the various solutions proposed sontune insulation:
· Low and narrow space:-reflective film set in the rafters, this solution is expensive and virtually ineffective in reality
· Middle and a narrow space: set-insulation between the raftersDelicacy of-implementation due to the irregular spaces between the rafters
· Strong and wide areaFor this type of insulation utilisersont: panels double-thick insulation is fixed to the inside of a box structure between failuresBlow a loose-fill insulation in cellulose or rock woolThis happens after installing ventilation baffles between the raftersFor the success of the roof insulation, you should know the roof of attics, the attic of living space and the roof terraceThus, the first kind is particularly highlightedThe reason is that it requires one or two layers of insulationThese can be mineral wool in rolls, with two layers of 20 cm cross, blown or loose, or in polystyrene
The action of the materials to insulate the roof
To use good quality materials, it is important to check beforehand on the thermal conductivity, heat resistance and fire resistance of these
-The thermal conductivity is a measure of quality of the material using the lambda coefficientMore value is low, it is more quality-The thermal resistance (R) is expressed in m² K / WIt determines the power of the material relative to the thickness of it in m² and with thermal conductivity (lambda)-The fire resistance (M) provides information on the material's ability to not ignite or spread the flames in the home
Information obtained from these three parameters are essentialFor if the insulation highly resistant to heat, the thermal insulation performanceThus, the thermal resistance must be greater than 0.5 m² K / W |
