Insulation – it’s more than what meets the eye

Building insulation refers broadly to any object in a building used as insulation for any purpose. Predominantly used for building insulation it adds to the building’s comfort and energy efficiency. Thermal insulation is the second most commonly used insulation wherein materials are used to reduce the rate of heat transfer. Soundproofing, also known as acoustic insulation ensures that the intensity of sound is reduced. Electrical insulation uses material to resist the flow of electric current and magnetism while another means is insulated glass which also saves energy. In recent times fire insulation and impact insulation (e.g. for vibrations caused by industrial applications) also play a vital role. The latest entrant in insulation is Fiberglass insulation, a man-made mineral fiber constructed from a variety of materials, such as sand and recycled glass. More than 90 percent of homes in America are lined with this pink stuff thus emerging as the most popular form of insulation in the United States. As the benefits stand, there are many apprehensions about the damage fiberglass can cause over time. It is known to cause health problems like immediate skin irritation, and some researchers fear inhaling fiberglass particles could cause cancer.

Insulating our buildings is one of the most imperative parts of any construction as insulation has a big effect on the cost of energy. As we have learnt in school heat naturally flows from a warm space to a cool space, and our homes and work places suffer from this transfer. Warm air from the inside will move to the outside and make us cold in winter. In contrast hot air moves from the outside to the inside and makes it uncomfortably warm in summer.

Unless your home and workplaces were specially constructed for energy efficiency, you can possibly reduce your energy bills by adding more insulation. Several older buildings have less insulation than buildings built today, but fret not, adding insulation to a newer building can pay for itself within a few years. To determine whether you require additional insulation, estimate how much insulation you already have in your building and how it is spread out. Invest in a home energy audit or an energy assessment. It will also help identify areas of your home that are in need of air sealing. An insulation check done as a routine part of a whole-house energy assessment done by a certified home energy auditor will also come in handy. One golden rule to remember is that before you insulate, you should make sure that your home is properly air sealed.

Fortunately we have heating and air conditioning systems to fix these problems, but the more opportunities warm air gets to flow out of or into the house, the harder those systems have to work. As those systems work harder, we use more energy and pay much higher utility bills. That is why HVAC insulation services sustain comfortable temperature indoors, with their manifold options. The best suited in terms of the return on investment (ROI) is the HVAC insulation through reflective insulation made by the sandwiched model of aluminium foil and polyethylene bubbled film. Available in two different variants of single bubble insulation and double bubble insulation films, the later one gives you the better protection against the needs of HVAC insulation because of its twin layered of polyethylene bubbles that responds very slow against the unwanted temperature change.

Proper HVAC insulation system is fundamental for homes and industrial constructions for its two prong benefit, it not only saves good amount of money by reducing the energy consumption but it also helps to reduce greenhouse gases released in the atmosphere, which is the need of the hour.
