How do we establish the efficiency of insulant materials?
The R coefficient and its metric equivalent, the RSI coefficient, are used to mark the efficiency of the insulating materials. The highest is the R or RSI coefficient, the more resistant to the movement of heat they are. All insulation products sold in Canada wear a R and RSI mark. The provincial construction codes requires minimums R and RSI coefficients for any new constructions, the values varies depending of the applications.It is important to know the requirements of the construction code of your area when planning a construction project.
NOTE: A proper installation of the insulating materials is important to ensure its efficiency. By compacting the insulating, letting spaces around it or allowing the air flow in the insulating reduces the real insulating value of the insulating materials.
What are the signe of a bad insulation?
DURING WINTER :
-The walls are cold to the touch
-The floors are cold
-The heating costs are higher
-The heat isn’t distributed equally in all the rooms
-Molds poliferate on the walls
-The air inside the house is too hot
-High air conditionner costs
-Unefficient air conditionning
-Molds appears in the basement
Is it profitable to insulate?
A good insulating system can make you save money, lower your energy consumption and make your house more comfortable. Keep in mind that the installation (including the modifications to the frame, the facing and the finishing coating) is usually the most expensive cost when doing insulation jobs. The local weather conditions also influence the profitability of the operation.
You’ll need to estimate the costs and the possible heat losses and gains in all the possible options. Then, analyze all the details in a way to master all the movements of the humidity. You can then choose the good insulating strategy. In doubt, consult a specialist.
During the last analysis, it is usually profitable to improve the insulation of a poor insulated house. In a new construction, it is simply logic to insulate the building properly so you do’t have to start over later.
What is an efficient insulating system?
Efficient insulating systems slows the movement of heat and restrain the movement of humidity at a reasonable cost.
TO DO SO, THOSE ASSEMBLIES OWNS :
- An air barrier to inside or outside air to penetrate the system.
- Well filled cavities who doesn’t let any empty space in the insulating or around and that doesn’t compact it.
- Minimal thermal points, in other words, those parts of wall that owns a low R coefficient and extend from the hot side to the cold side of the insulating, allowting the heat to escape easily. The walls structural elements frequently create thermal bridges.
- A vapor barrier, like a polyethylen membrane, that keeps the moisture from going from the warm areas to the building envelope, colder, there it could condensate.
- A drying potential, or the capability of the insulating system to let go any kind of moisture who enters.
What are the noises and the clues of sound transmission?
To get a better understanding of our needs in soundproofing, we need to establish the noise level in our residence. The noise is measured in decibels. A jet plane produces somewhere between 120-140dB. A normal conversation produces about 60dB, when a fridge produces around 40dB
The goal of soundproofing is to lower to the maximum the noises who are likely to disturb your acoustic environment. First of all, it is important to identify the source of the noise : is it an impact noise, like footsteps or a voice sound? Sounds are like water. If there is a weakness somewhere, the air or the vibration is going to sneak out.
The sound transmission class (STC) is the ability of a partition to block the passage of aerial noises. The construction code, dating of 2005, requires an STC of 50 for the walls of a semi-detachez residence. Which is not always enough.
What are the materials that allows a better soundproofing?
To adequately insulate a room or an appartment, there is a few foundamental principles to consider before starting the job. Namely, the mass, the uncoupling and the drum effect. The materials need a certain mass, because the heavier it is, the more it insulate.
Second, the uncoupling allows to avoid the rigid contacts to stop the passing of vibrations from a place to another.
Finaly, we have to avoid the drum effect coming from the conception of the soundproofing of the walls or the floorings.
There is a lot of ways to soundproof a room and dozens of materials exists on the market.
