A Guide to Home Insulation

August 29th, 2012

Home insulation does the work of an air-conditioner and a heater for you. If you insulate your house, you are converting it into a cosy place as it neutralises the temperature in your rooms. Insulation keeps your walls, ceilings and floors warmer in winter and cooler in summer. It is important to insulate your attic, floor, basement, crawl spaces and exterior walls. Finding the R-value If you want to minimize your increasing utility bills, home insulation is an affordable solution. If you need to know how much insulation is required for your house then you need to know the R-value of insulation. R-value indicates how much heat flow an insulator will resist. Higher the R-value, greater the resistance to heat flow. Usually, the thickness of insulation for any house ranges between 40 mm to 75 mm. If you have a bigger budget, then you can add another layer of insulation. Before you insulate Home insulation depends on factors like weather conditions, structure of your house, consumption of electricity and even family lifestyle. You also need to ensure that your house is air tight. This can be done by ensuring moisture control and sealing air leakages. Air leaks through small openings around doors, cracks in the walls or even chimneys reduce heat transfers, thereby preventing effective insulation. Selecting the right insulation material Choosing an adequate insulation maybe difficult but not impossible. There are various types of insulation materials available in the market.  The most commonly used insulator - blanket insulation is made up of fibreglass, mineral wool, plastic fibres or natural fibres and comes in the form of batts and rolls. Other options include concrete block insulation, made of foam beads or liquid foam, and foam board insulation, which can be used in any part of your house. Both these insulators are available in Polystyrene, Polyisocyanurate, and Polyurethane material. Insulating concrete is another option, which is inbuilt during the construction of houses. With technological advancement, we now have insulators like polyester fibres that are made from recycled plastic bottles or loose-fill that are woven into flexible mats. Reflective insulation is widely used as it is effective at reducing heat flowing earthwards. Picking an experienced contractor If you are unable to determine how to proceed, you can hire an insulation contractor. An insulation contractor specialises in installing thermal insulation. You will need to make sure that the contractor has a proven track record and has knowledge on the different kind of insulations. The expert will guide you rightly in improving your home. Contributing to the environment You can also install home insulation yourself and save a lot of money. You also contribute to the environment as you are reducing the carbon emissions generated from your heating systems. Proper home insulation also diminishes dampness or condensation thereby helping you save on re-painting costs. It also acts as a soundproof, reducing outside noise levels. Remember, you can save the environment by being eco-friendly and home insulation is your contribution in keeping your country green.
