Importance of proper housetop insulation
Roof insulation
A functional roof has to fulfill some demands to be called a proper roof. For example it has to provide conditions for adequate insulation, ventilation, piping and so on. Probably one of the most important things, one that is basically entwined with every aspect of your life, is insulation.
Why is roof insulation so important?
Generally speaking, the overall structure of your house acts as insulation. The roof, doors, windows, the distribution of rooms, it all plays a major part in insulating your home. It is common knowledge that around 40% of the heat is lost through the roof. So in order to maximize your energy potential, reduce the heat lost through the roof and finally to reduce your energy bills, you have to consider a lot of factors.
When referring to insulation, one can think of either specific materials used or of special techniques and designs that provide another layer of insulation.
When upgrading or constructing your insulation system, there are some things you should bear in mind. For example, you have to take into consideration the building design, budget, personal preference, and most of all, climate. While universal building codes provide minimal guidelines, it is up to each state to enforce additional requirements based on the climate of the area.
Types of insulations
Generally speaking, there are two main types of building insulation based on the material used. First, there is the bulk insulation. Focusing on providing maximum resistance to three components of building heat transfer, they block conductive and covective flows out of the building. By using low-density air placed between fibers or inside plastic bubbles, this type of insulation is perfect for an actively cooled building. Its performance may falter when used on passively cooled buildings.
The second type of building insulation is the radiant heat barrier. As the name suggests, radiant heat barriers reflect the heat instead of absorbing it. By using it in hot climates, it provides maximum efficiency in attics, ceilings and roofs. They require regular maintenance since a film of dirt can alter the performance of the barriers.
Wood fiber is a well-known organic insulation bord that can be impregnated with asphalt in order to enhance the roofs moisture resistance.
Perlite insulation boards are mostly inorganic. The top surface includes an asphalt coating that serves the purpose of limiting adhesive absorbtion of any possible fluids and debris.
Polyisocyanurate is a plastic insulating core placed between either organic or inorganic facers. While its insulating efficiency remains higher than any other type, there is a possibility of a slight reduction in thermal resistance properties of the roof.
Also, there exist polystyrene, extruded polystyrene, cellular glass and gypsum boards types of insulation.
Eco-friendly insulation
Like anything else today, there exists an eco-friendly type of insulation. When it comes to defining the concept, it has to meet the condition of having a significantly lower, and most of all limited, environmental impact. The fastest way to check whether your insualtion is eco-friendly or not, is to do a life-cycle assessment.
