Sealant Technologies offers an affordable way to take an old and existing wood kiln, which has a lot of air leakage and transforms it back to its original design. AireBarrier Black can be sprayed and will adhere to most material, including old wood, rust metal, concrete and even other plastics to form a smooth, plastic type surface which seals leaks. By air sealing wood kilns up, it is possible to preserve an older wood kiln and allow it to operate more efficiently well into the future. AireBarrier Black is a high density polyurethane air barrier which is why it works so well especially when combined with the Spray Pod 1.0 portable spray sealants machine. 

A conventional kiln is relatively simple to operate and maintain and it is a cost-effective technology for wood drying. The downside of this technology is energy efficiency. A conventional kiln consumes around 50% more energy than that required to evaporate the water. Energy consumption in a conventional kiln is required for moisture evaporation, heating the kiln and lumber, kiln ventilation, thermal losses, air leakage, and air humidification. Air barriers are effective ways to bring energy efficiency to any older wood kiln.

Kiln maintenance could reduce air leakage and reduce the humidification requirements, but the benefits in terms of energy savings are usually small. Higher reduction in energy consumption can be achieved by dehumidifier units, vent heat exchangers, and air drying, but these strategies usually require considerably modifications to an existing commercial process.

Air barriers are systems of materials designed and constructed to control airflow between a conditioned space and an unconditioned space. The air barrier system is the primary building enclosure boundary that separates indoor (conditioned) air and outdoor (unconditioned) air. Air barrier systems also typically define the location of the pressure boundary of the building enclosure. Energy efficiency is accomplished when a building enclosure is tight. Air Barriers are an emerging sealant technology which will change the way that buildings are constructed.

AireBarrier Black controls the unintended movement of air into and out of a building enclosure. This unique sealant, developed by Sealant Technologies, will change the definition of air barriers in terms of performance and affordability. Because AireBarrier uses high density polyurethane technology, the combination of speed and easy application provides a tremendous way to achieve high performance on your project. If air leakage is a major concern for you and your building envelope, then this technology will provide the significant ROI that you are looking for.

AireBarrier will fully-adhered to most surfaces, providing a seamless, monolithic air seal that conforms to irregular shapes, slopes and allows easy detailing around penetrations such as pipes, windows, doors and sheathing fasteners. Polyurethane type air barriers contribute to improved building durability, energy efficiency and to occupant comfort, health and safety.
