The attic insulation requires a special approach when isolated and carefully selected material. If the main walls themselves are in some way a heater, then not every roof is thick enough to become a reliable barrier against cold according to attic insulation whitby.
Therefore, you need to know exactly which insulation is better for the ceiling and how to make it suitable for living in it at any time of the year.
Due to the design features of the attic, the heat losses in the attic always increase compared to the rooms behind the walls. In addition, the upper part of the ceiling does not have a thermal “cushion”, which plays the role of the ceiling of each house. So, roofing services Oshawa can conclude that the walls and roof of the ceiling are most susceptible to freezing in the winter, so you need to choose the right insulation and calculate its thickness.
The ceiling always needs special quality insulation
The most popular heaters that are fixed directly under the roof are: polystyrene (conventional foamed or extruded), polyurethane, eco cellulose, and all kinds of mineral wool.
These warming materials are well fixed by Roofing Companies between the crate or adhere to the inner surface of the roofing material and make the cold ceiling a warm room suitable for use.
In houses located in cold areas, it is necessary to arrange this material in two or even three layers. Sometimes, in combination with one of the heaters, an infrared cover is used that is fixed to the ceiling walls and includes this additional heating as needed.
Criteria for selecting a heater in roofing services Oshawa
When choosing a material, it is necessary to take into account a number of characteristics that determine the efficiency and safety of the insulator:
- The heater must have minimal flammability and low thermal conductivity.
- The density of the material should not be too high, otherwise its thermal conductivity increases and the ceiling structure becomes heavier, which is very undesirable as the load on the load-bearing walls of the building increases.
- Installation of the heater must be simple and the service life is comparable to the durability of the entire roof structure.
- The ecological purity of the material is one of the main criteria for its selection – it must not emit unpleasant odors and do not degrade substances that are hazardous to human health.
- Characteristics of insulating materials for the ceiling
To find out more about the properties of each heater, you need to think more carefully.
Foam (expanded polystyrene)
The Styrofoam material has a rather rigid structure, consisting of separate foam portions tightly connected to each other. But if you look at the volume content, this material contains only 2.5% polystyrene and 97.5% air. Therefore, when applied, cold does not allow entry into the room is the air layer created by this heater.
