The easiest way to check if you have insulation in your walls is to carefully remove a powerpoint situated on one of the exterior walls, and with a torch look into the wall cavity.

No. The material has been developed strictly to fill the enclosed space between inner lining and the outer cladding of exterior walls of buildings.

Yes. Your licensed AIRFOAM™ Installer will work with you to suit your particular needs.

This will depend on the age and/or construction of your house, and should be discussed at the time of quotation.

The unique nature of AIRFOAM™ being a liquid foam with the consistency of shaving cream when injected, allows it to flow around any obstacles including water pipes and wiring without getting caught up, filling the entire cavity.
Your licensed AIRFOAM™ installer is a professional and approaches every job in a tradesman like manner, by applying a combination of techniques including; timing the cavity fill, methodical placement of the insertion holes, and back-pressure out the insertion hole, he is able to ensure a cavity is fill.

The initial water content of the foam is 4% by volume, that is too low to affect building structure. The open-cell nature means the foam quickly dries out and, once dry, AIRFOAM™ is hydrophobic and resists reabsorption of water.

A common misperception with brick construction is that the gap between the timber stud and brick surface is there for ventilation. Although this is needed, the primary purpose of this gap is to prevent moisture travelling through the brick which is porous, and touching the timber stud. (If timber studs were in contact with brick they would not take long to rot). AIRFOAM™ being breathable, whilst at the same time repelling water, fills the whole cavity space providing a suitable thermal barrier, inhibiting any moisture transfer, and allowing the walls to breathe.

There is very little disruption to the household during the AIRFOAM™ process. Installation typically takes 1-2 days to complete. During the initial foaming process powerpoints are unscrewed temporarily from all existing walls to prevent foam flowing into them. During the following 30 day curing period your AIRFOAM™ Installer will advise you of certain ventilation procedures to follow, which normally includes keeping several windows ajar during daylight hours to assist with the AIRFOAM™ drying process.

No. Even though there is intense heat, AIRFOAM™ will not melt away. It will char, lose weight and volume but remain in place as foam.

AIRFOAM™ is a modified plastic foam containing millions of tiny air cells - very effective as insulation. It is non toxic, does not create a fire hazard, and is a breathable, water repellant foam.

No. Unlike some plastics, Airfoam will not react with plastic coated cabling.

No. AIRFOAM™ is hydrophobic - It sheds water rather than holds it. Even when immersed in water, AIRFOAM™ absorbs only a small amount of water which quickly evaporates when it is removed from water.

No. There will be no odour once the foam is cured. In a small number of cases there is a perceptible odour while the foam is curing. This can be avoided with adequate ventilation.

No. Some initial shrinkage is normal but investigations show that AIRFOAM™ maintains its physical and insulation properties. In fact, 15 and 20-year-old foam has been found equivalent in insulation performance to new foam.

Definitely not - as long as the foam can dry in reasonable time. Extensive field investigations have determined that AIRFOAM™ does not contribute to the development of fungus. Houses of over 200 years old were included in the investigations.
