What Insulation Specialist could help You the Homeowner with:
Insulation in buildings is for thermal purposes mainly, this term also applies to acoustic insulation, fire insulation, and impact insulation. Very often insulation will be chosen for its ability to perform several of these functions at once.
Thermal insulation in domestic premises is an important factor to achieving thermal comfort for its owners. Insulation reduces unwanted heat loss or gain and can decrease the energy demands of heating and cooling systems. It does not address the issues of good ventilation and may or may not affect the level of sound insulation.
Insulation can refer to the insulation materials employed to slow heat loss, such as: glass, cellulose, wool, rock wool, polystyrene, urethane foam, vermiculite, perlite, wood fibre, plant fibre (flax, cotton, cork, etc.), recycled cotton denim, plant straw, animal fibre (sheep's wool), cement, and earth or soil, but it can also involve a range of designs and techniques to address the main modes of heat transfer - conduction, radiation and convection. Many of the materials in this list deal with heat conduction and convection by the simple trapping large amounts of air (or other gas) in a way that results in a material that employs the low thermal conductivity of small pockets of gas, rather than the much higher conductivity of typical solid materials.
The effective use of Reflective Insulation (Radiant Barrier) is commonly evaluated by the Reflectivity (Emittance) of the surface with airspace facing to the heat source.
The use of bulk insulation is commonly evaluated by its R-value. For attics, it is recommended that it should be at least R-6.7 metric. However, an R-value does not take into account the quality of construction or local environmental factors for each building premises. Construction quality issues include inadequate vapor barriers, and problems with draft-proofing. In addition, the properties and density of the insulation material itself is critical.
How much insulation material installed in a house depends on building design, climate, energy costs, budget, and personal preferences. Regional climates make for different requirements.
The insulation strategy of a building needs to be based on a careful consideration of the mode of energy transfer and the direction and intensity in which it moves. This may alter throughout the day and from season to season depending of the area the house is built in.
It is important to choose an appropriate design, the correct combination of materials and building techniques to suit the particular situation and personal preferences.
Thermal envelope defines the living space in a house. The attic or basement may or may not be included in this area. Reducing airflow from inside to outside can help to reduce convective heat transfer significantly.
The less natural airflow into a building, the more mechanical ventilation will be required to ensure human comfort level. High humidity can be a significant issue associated with lack of airflow, causing condensation, destruction and rotting construction materials, and encouraging microbial growth such as mould and bacteria.
Also, an effective insulation of the domestic premises can sufficiently reduce the heating and electrical bills.
Therefore, a reputable contractor is required to address all those issues.
