Open Cell spray Foam
In open cell spray foam air is allowed to slowly flow through the cells for better ventilation, it is permeable; able to 'breathe'.
This type spray foam is used where ventilated insulation is required, allowing vapour to escape yet minimising wind movement when expands up to 200 times the size when applied to an area.
Open Cell Foam Insulation
Open-cell foam are not used for exterior applications, they are cost effective per unit of U-value without providing structural contribution to a building that closed-cell foams offer.
It is used for attic insulation, wall cavities and domestic insulation in the home mainly.
Open Cell Spray Foam Insulation
It offers excellent acoustic properties and is a good type insulation for soundproofing and noise reduction. Open cell foam is a quality thermal insulation that will not sag or rot and needs no maintenance.
