A closed-cell polyurethane foam insulant can be sprayed directly onto the internal surfaces of a potato storage building. Using this method of insulating the facility substantially reduces the risk of damaging potatoes, according to the British Urethane Foam Contractors Association (BUFCA).

During cold spells in winter, the internal surfaces of agricultural buildings can become wet with condensation and severely damage the potato harvest. By insulating the building this risk can be substantially reduced.

This will insulate the building and help to regulate the temperature, so that sudden hot or cold temperature variations are not so likely. As the insulant is sprayed directly on to the building substrate, this helps to seal the building and control internal temperatures.

Insulating the agricultural building allows the sugar levels of stored crops to be maintained for longer, and lower temperatures can preserve potato quality.

Farmers know that the risk of condensation, freezing temperatures or the lack of a controlled temperature environment may be disastrous for potato crops. A simple application of sprayed foam can help to maintain a healthy potato stock.
