Insulation is the phenomenon of producing the resistance to heat, electricity or sound. Insulation is mainly used in the house to prevent heat gain and heat loss from the surroundings. Most electric appliances like Heaters, refrigerators and Freezers use insulation technology. For better effectiveness, Insulation should be installed in the barriers between heated and non heated parts of the house. The idea is to reduce the flow of heat and air between the heated and non heated space.
One of the main applications of insulation is house insulation. An insulated home is more energy efficient, requires less maintenance and is more comfortable as the temperature remains uniform over weather changes. Insulation at home helps in saving energy and reducing utility and repair bills. It makes the house more comfortable. It prevents damage from leaking water and provides a good thermal resistance. An insulated house is worth the money spent on insulation.
There are many types of home insulation available in the market these days. All insulations have their advantages and disadvantages. They are mainly differentiated based on the material used for the insulation. They can be distinguished into Plastic foam, rigid board, reflective, loose fill, batts and blankets and blown in insulation etc. The type of insulation preferred should be based on budget, the requirements and the weather condition of the surroundings where the house is situated.
Spray Foam insulation is useful in insulating the basement, walls and ceilings of your home. Spray foam insulation helps in keeping the house warmer during winter and cool in summer. Spray Foam insulation is performed with a material known as polyurethane. The liquid Polyurethane is pumped up in the holes and cavities with the help of high pressure containers. It expands after spraying filling all the gaps tightly. Spray foam insulation cannot be performed by homeowner and requires a team of professionals.
There are two kinds of spray foam insulation available in the market. One is Open cell that is installed with Isocyanurate and another is closed cell performed with the help of Polyurethane. The closed cell foam provides a higher R value than open cell foam insulation. R value is an Insulation measurement term used to measure the Spray Foam insulation.
This type of insulation is neat and gets sprayed in all the small holes and cavities in the house. It is highly thermal-resistant and insect-resistant. It makes the house air tight resulting in low utility bills and a cleaner house. It reduces the cost spent on heating and cooling equipments. Spray Foam insulation helps in moisture condensation.
Spray Foam Insulation is a bit more expensive than Fiber glass insulation but it would last longer than the latter. Also, it would not keep falling off the wall like fiber glass insulation. A person would not even find the insulation particles floating in the air like fiber glass insulation. Spray Foam insulation is better to be performed while constructing the house rather than in already built structures. Most spray foams do not cause any environmental concern. But Some Spray foams contain hazardous chemicals that can cause skin related problems and lung cancer. Therefore, spray foam should be installed with proper precautions.
