Heat is exchanged through three modes of heat transfer namely conduction, convection and radiation.It is the desire of every homeowner to recline in a room that offers thermal comfort, especially when the temperature outdoors is unbearable.
In fact, it is a requirement in most modern regions that homes being constructed should be insulated. When two sections in close proximity are at different temperatures, the flow or heat from the hotter sections to the cooler ones is inevitable. Proper home insulation reduces heat transfer between the interior and the outside environment.
How You Loose Heat in Your Home
Conduction refers to heat transfer from one point to another through a good conductor of heat such as a piece of metal. On the other hand, convection is movement of heat through a liquid or gas (or air) while radiation refers to heat transfer from a warmer body to a cooler one through space.
Insulation Materials – Your Options
Several materials can be applied to minimize movement of heat or cold from the outside environment to the house or vice versa. The working principle of all these materials is based on the modes of heat transfer mentioned above.
Some solid materials are naturally poor conductors of heat and they act as insulators against heat transfer. For instance, fiberglass, wool, polyester, rock wool, and cellulose fiber are poor conductors of heat and they serve as excellent insulators for commercial purposes.
Most of these leave small air sacs within their tight fabric, which impedes heat transfer. When such materials are overlaid on the floor or above the ceiling, they greatly minimize exchange of heat between the inside and the outside environment.
Other materials minimize heat transfer by reflecting heat from a warmer object instead of absorbing it. In addition to reducing heat transfer, most thermal insulators also reduce the noise levels and absorb shock, making the room even more comfortable.
Insulating A Existing Home Versus New Construction
When insulating a house that is already constructed, almost all the walls should be considered for insulation. However, there is one most important part of the building that should be given top priority—the attic. This is the area that falls directly below the inclined roof of a house, above the ceiling. In most cases the attic is well lit, ventilated and maintained and may be used as a study room, a bedroom or a home office.
Start By Evaluating The Need For Additional Attic Insulation
Nevertheless, some attics are dark and neglected. This applies especially to those attics beneath highly pitched roofs, which makes it appear awkward and with several spots that are uncomfortable and hard to access or clean. As indicated by research, the most heat is exchanged through the roof.
As a result, the section just beneath the ceiling is always warmer than the floor while the attic is even hotter. This fact therefore affirms the need to insulate the attic adequately.
One of the simplest methods of establishing whether or not the attic insulation is adequate is by estimating the depth of the insulation. If the insulation well covers the joists without leaving much exposed parts, it may be adequate.
You can also contact a professional insulation contractor like Craftmasters Insulation Minneapolis and most will offer to conduct a free home energy inspection.
Do It Yourself or Hire a Contractor?
One should also examine whether the insulation is evenly spread across the room; if not, some more filling may be necessary. Lastly, one should consider whether he/she needs to hire home insulation experts or a DIY approach can serve the purpose.
