Open Cell

sprayfoam-opencell

A very popular insulation material used nowadays is the open cell insulation which can be used in different methods. Ease of use, lightness surpasses other insulation materials and is also environmental friendly.


Mechanism

Water is used as the blowing agent and plastic as the main material which then oxidizes with air to form CO2 bubbles thereby expanding the actual material. The bubbles burst before plastic sets but leaves small gaps within the foam and hence the name; Open Cell Insulation. Because of its structure there is vapor transfer through the material which provides better attic conditioning in hot summers and roof insulation during freezing winters. This also avoids wood rotting as there is no water vapor trapped between the insulator and sheathing.


R-value

A measurement of insulator performance, open-cell foam has an R-value of 3.5 to 3.6 per cubic inch which is comparable to others but does not degenerate with time.

Weight

Lightweight at just half a pound per cubic roof, it is much easier to use than other materials.

Cost

Averaging at $0.40 to $0.50 per board foot it is more advantageous financially and is also a greener option.

Sound Reduction

Reducing noise transfer and eliminates noise from pedestrians, heavy traffic and airplanes.

Eco-Friendly Option

Cut down costs by home weatherization as this material blocks air leaks and insulates well. Also optimizes temperature control without using coolers and heaters. So you can save money and claim rebate from government and utilities by having a greener home.
