Factors to Consider When Choosing Insulation Contractors
The roof, the walls, and the floor are some of the places that your house is losing heat through- this is right places for installing insulation.
Do you require Insulation?
The first thing is that you should confirm if you have Insulation. You can verify this by checking the ceiling joists you may be able to see colored fiberglass. If the walls have patched holes, then it is a sign that there is insulation.
Houses built in the 1940s are quite drafty which allow air both warm and cold to leak into the house. You may also be losing heat from your home through fire places and chimneys. You may also lose heat through ducts, electrical outlets, and air leaks. Given that when the air is warmed, it rises and goes to the top of the house because it becomes less in weight. Thus, heat can escape the house through the roof, and it is crucial to, therefore, insulate the roof to avoid losing heat through the ceiling.
What form of insulation do you use?
There are four general categories of insulation:
- Expanding sprays (proprietary systems).
- Loose fill material-glass fibers, mineral, and cellulose.
- Batts-includes cotton, various wool, and fiberglass.
- Rigid boards entail glass fibers and plastic, (composed of plastic foams or glass fibers);
When insulating unfinished places i.e. attics rigid and batt insulation stereotypically come into play. Also, if and when you are replacing walls rigid and batt is the insulations of choice.
Loose fill is the proper insulation for old homes as it may reach places other insulators may not reach also known for having little to no effect on the finishing already in place.
I f you choose the loose-fill cellulose (recycled newspaper) insulation that is treated with borates as a fire-resistant substance instead of insulation that has been treated by aluminum sulfate-which react with moisture forming sulfuric acid and can damage most metals, wood, brick and stone. Borates are compatible chemically and physically with the existing old-house materials.
How much insulation is required for your house?
The material’s thermal resistance heat flow depends on the region of the country you live in and the room being insulated. The higher the heat resistance to heat the better the material used to protect. Thermal heat resistance has a range of between zero to forty. The Energy Department has a site solely to show the thermal heat resistance of one’s region. The higher the thermal heat resistance, the better the material insulates.
