Comparing Open Cell vs. Closed Cell Insulation
When you evaluate open cell vs. closed cell insulation, there are cost differences that you may consider when designing your next project. A light density, open-cell spray foam insulation like Icynene Classic, can be installed at a significantly lower cost than a closed-cell foam in projects targeting the same R-Value* specification. Some restriction may apply with interior space limitations.
Closed cell spray foam exterior applications
Can be applied at very low temperatures (as low as 5oF)
Adds wall racking strength as well as impact resistance
Ideal for continuous insulation solutions
Higher R-value* per inch – easier to accommodate high R-value* requirements in narrow spaces
Lower vapor permeance (can be a Class II VDR)
Can reject bulk water (ideal for flood zones)
Higher tensile and bond strength
Open cell spray foam interior applications
Can be installed at a significantly lower cost and target the same specified R-value*
Can achieve greater R-value* if not restricted by space
Lower raw material/resource use
Permits bi-directional drying
Will accommodate long-term creep and seasonal movement
Air barrier and insulating material
What is Icynene Spray Foam Insulation?
Icynene spray foam insulation is an insulation and air barrier material that seals walls, floors and ceiling cavities against air movement, including spaces around electrical outlets and light fixtures and where walls meet windows and doors. Icynene spray foam insulation can provide an effective air barrier insulation to minimize air infiltration through walls and ceilings, preventing drafts, cold spots and energy loss. The performance of Icynene spray foam insulation means that humid indoor/outdoor air is restricted from entering the walls & ceilings and condensing, thereby minimizing the possibility of moisture entrapment & build-up within the wall & ceiling cavities. This is conducive to preventing building envelope failure due to moisture damage.
Icynene spray foam insulation products include half-pound, open-cell and two-pound, closed-cell solutions which can be used separately or in tandem within a project to provide long-term thermal comfort and air sealing. Icynene spray foam insulation products are installed by extensively training and licensed Icynene® contractors only.
