Renovating house: thermic insulationNovember 27, 2017
Thermic insulation helps to define the comfort of a home: it reduces the heat loss to the outside in the cold season and the heat input into the hot one.
Adequate insulation with the use of appropriate materials also has other advantages: it can break down noise and reduce excessive moisture or dryness, resulting in improved internal well-being. In addition to the internal temperature, the house’s thermic comfort is also influenced by the elements that surround the house: walls, floors, ceilings and glasses, the more they are cold and the more they tend to absorb heat.
The feeling of well-being is in fact felt when the temperature of the walls added to that of the air is slightly higher than that of the corporeal. Here’s an extra reason to insulate properly: you live better and reduce your consumption. But where to intervene?
Insulate the walls
The most dispersed walls are the outer perimeter walls that surround the outside environment, so they will be the first to be insulated, even to dispose of water vapor from the interior. Usually the coat technique is used by imbianchino, either in the interior or exterior, in situations where the thermic excursion between night and day is very strong.
The first system is made with specific panels that are superimposed on the structure, inside or outside; is suitable for existing buildings because it reduces discomfort during operation and does not involve demolition. For those who live in a villa or an independent home, it is the best way to achieve good insulation, while in condominiums you need the owners’ permission. In new constructions it is used to insulate in the cavity between the wall walls: inside there are insulating materials of different nature and composition depending on the type of masonry and the problem.
Insulate the soles
Floors over unheated spaces such as porches, cellars, or garages need more insulation, similar to the ceiling ceilings on the top floor or the lower level of undeveloped attics. The insulating layer applied to the ground can be made of panels or other products. Also to insulate the ceilings the modalities may be different: in general, a false ceiling is used and the insulator is added to the cavity. Alternatively, this material applies directly to the ceiling.
Insulate the roof
During the winter season in homes through the roof is dispersed the greatest amount of heat: even 40% of the energy produced by the heating system is reached. In summer, however, the roof contributes decisively to the overheating of the underlying environments. It is not convenient to insulate the roof if the attic is not practicable or used as a deposit, but it can be resolved to isolate it on the ground, intervening on the attic that separates the underlying house.
