Most of the energy costs spent to keep a Chinatown home warm in the winter and cool in the summer end up leaving through the attic. In the summer, the sun’s heat pours in through the attic and in the winter, warm air rises past the ceiling and out of the home. Saving on energy costs starts in the attic, but how much insulation is enough?
Are You Trying To Find Loft Insulation Companies For Your Chinatown House?
Although spray foam insulation as we know it today truly emerged in the 1980s around the Chinatown area, spray foam actually has its roots several decades further in the past, beginning with the development of polyurethane foam in the 1940s by Otto Bayer. Otto Bayer, an industrial chemist, actually began working with polyurethane in Germany during the late 1930s. This technology was brought to the United States in the early 1940s by David Eynon, the president of Mobay, a war effort conglomerate created from the partnering of two chemical industry giants, Monsanto and the Bayer Corporation.
All About Spray Foam Insulation
An energy efficient home is an environmentally sound home and to achieve energy efficiency insulation is vital. It must be used liberally, and it must be properly installed. There are all sorts of insulating materials, and their green credentials may vary.
The most common is Pink fiberglass Batts which are by no means the worst from an environmental perspective but they aren't the best either. Fiberglass itself is chemically inert, but the glues and backing materials that provide structure to the batts can release dangerous fumes and there is some concern that minute particles of fiberglass can filter into living spaces, presenting a health risk. Rigid polystyrene panels, another popular choice, are made from petrochemicals which are flammable and emit toxic fumes when burned.
Misconceptions about Cellulose:
1: Prone to mold and insects; Cellulose Fiber is treated with two non-irritant, non-toxic, safe to handle allergy free agents; Borax and Boric acid which make it vermin resistant.
2: Fire retardant chemicals disappear in 5 years; The most exhaustive study and technical literature review concluded it would take 300 years to do so and only under continuous harsh conditions of 100% relative humidity and 70 degrees Celsius.

Home Insulation - Choosing the Best Material for Your Home
Movement of air in and out of a home can be a leading cause of escalated energy bills. Air can enter your house through holes, cracks and crevices. You can stop unconditioned air from entering your home and indoor conditioned air from escaping outside by adding an advanced insulation system to achieve optimal building performance.
A small science lesson about insulation:
Heat moves from warmer areas to colder areas. This is the single basic principle on which the idea of insulation is based. On hot days heat tries to get inside your house and on cold days the heat tries to escape. Insulation seeks to minimise this ebb and flow of temperature by slowing the process.
Unfortunately no matter how good your home insulation is, any building always needs a constant supply from a heat generating source to maintain a steady temperature. Of course however, if you have good insulation then you will need much less heat and thus a lot less energy to achieve the same effect.
Most of us learned in GCSE science about conduction convection and radiation.
Here is a brief summary of each to refresh every ones memory.
o Distance between surfaces
o The emissive of the surfaces (shiny and light/matt and dark)
o Temperature differences between receiving and radiating surfaces
The application of thermal insulation does not have the effect of generating heat in your house. It is still always the rule that you will have to supply heat from an inside source. There may be a rise in temperature inside the building after the installation of insulation but that will be down to the better performance and energy saving properties of better house insulation.
