Insulation for Hawaii Home

The government of Hawaii has introduced various new programs for encouraging the Hawaii citizens towards taking a step for making their homes more green and energy efficient. The most important part of any energy efficient home is insulation but adequate insulation is also not suitable. It is harmful to add insulation to a pre-insulated house.

A point of diminishing is reached on additional insulation to a pre-insulated house. Before reaching this point insulation helps in reducing the cost of energy by 1 dollar for a definite time period.

Once this point is reached it would cost you 1 dollar more for the energy cost. Hence it is not advisable to insulate the house once the point of diminishing is reached.

The International Residential Code (IRC) 2009 is the main place for looking the point of diminishing returns. It consists of all the minimum requirements needed for insulation of any house in Hawaii. These requirements are quite close to diminishing returns but not at the verge of it. For example, if the minimum IRC in warmer conditions is R-30 than increasing it to R-35 or R-38 would reach to the diminishing point. This might not be suitable for energy efficiency.

They have divided the IRC climate zones in to three different categories. First these zones were divided into eight zones but as some zones have similar conditions they were then simplified together. You may even contact the local building officials to get the information about insulation requirements.

In Hawaii the best suitable type of insulation for residents is the Spray foam insulation. Spray foam insulation helps stopping all the air and moisture infiltrations in the house. It even makes home more comfortable and saves a lot on energy costs. It strengthens the structure of the building and makes it strong than before.

Once the insulation is installed it is permanent. Spray foam insulation keeps the dust and pollen out of the house. It eliminates all the ice damaging and improves the quality of air. Over and above it meets all the building codes of Hawaii.

The concrete block type of insulation is also suitable for Hawaii homes. The materials used in this insulation are polystyrene, polyisocyanurate or polyiso and polyurethane.

This insulation is usually applicable on unfinished walls including the foundation walls as well as for new constructions and most probably in major renovations. This insulation requires minor masonry skills. This type of concrete has 10 times more insulating value than ordinary cement concrete.

The loose fill insulation recommended for enclosed existing wall or new open wall cavities and unfinished attic walls where it is hard to reach is made up of cellulose, fiberglass and mineral wool. Mostly it is blown at required place with the help of highly modern equipments. This is very good for insulating the finished existing areas of the house as well as around the obstacles.

For unfinished walls, ceilings and the floor the reflective systems insulation is used in Hawaii. This insulation

is made using foil faced Kraft paper, plastic film, polyethylene bubbles and cardboard. The installation of this is also very simple using frame studs joint between the beams.

This insulation can be installed by you manually. In case of irregular framing or presence of obstacles bubble foam can be applied. It is effective in preventing downward flow of heat what so ever it eventually depends on spacing.

If you are having problems of high temperature than rigid fibrous or fiber insulation is best suitable for you. Fiberglass mineral rock or slag wool is employed in preparation of this kind of insulation.
