Case Study: Foamseal Spray Foam in Agricultural Applications

This outstanding conversion of a series of barns by multi award winning developer John Langdon of Heritage Oak Buildings is set in the picturesque village of Lavant, just outside the historic city of Chichester in West Sussex.

Foamseal spray applied polyurethane foam is a common form of insulation in potato stores, chicken houses, mushroom sheds and piggeries and animal shelters. The foam provides excellent insulation and sealing for stores and the surface finish is robust to ensure that best practice hygiene measures can be maintained.

Hygiene Maintenance

Foamseal can be power washed at pressures up to 500 psi and at temperatures up to 40/50oC. The foam is chemically resistant to all common insecticides and fungicides and is not attacked by mild acids or alkalis. Removal of dust and disease spores is critical for minimising disease risk. Recent surveys of potato growers have shown that there storage hygiene policy is often limited to sweeping or vacuuming only which can result in re-distribution of disease spores. Power washing and disinfection is the most effective way of removing dust and killing disease spores and Foamseal will remain intact provided sensible treatment is applied.

There is no nutritional benefit to pests, vermin or bacteria.

The foam can be installed as soon as the roof is weathertight and is carried out by Foamseal approved and certificated, qualified installers. The flint stone solid walls were previously studded out with 70mm CLS studwork (or Gyproc metal studs can be used) set slightly off the wall to allow the foam to get behind the studwork to provide a weatherproof seal against driving rain and rising damp. A perfect air tight seal between the walls and the roofs of the barns is created in a seamless coating of foam. Any fungal growth on the wall surface is prevented and the foam eliminates any space for insects or rodents.

Old Foam Applications

Foamseal and other polyurethane foam applications can be refurbished by applying another coat of foam directly over existing applications which may have been subject to mechanical damage or decayed by ultraviolet light. This will provide a complete covering which is as good as new. For repairing or rejuvenating smaller areas Foamseal portable foam packs can be used.

These are completely self-contained, 2 part polyurethane foam packs formulated as closely as possible to our bulk material. The foam can be sprayed or injected and has perfect adhesion to existing foam surfaces. It is as chemically and physically robust as the bulk material.

New Products

Foamseal have launched Urespray F – 75 hybrid polyurea a very hard smooth and wear resistant surface which can be applied onto just about any surface including existing old foam. It will resist steam and pressure washers, when used sensibly, up to 2000 psi and 80oC. It can be provided in a limited range of colours. The surface hardness prevents the ingress of wood boring insects, such as weavels and helps protect foam from attack by pigs, birds and other vermin. A number of field pig shelters have recently been treated with Foamseal to prevent condensation and provide insulation. Urespray F – 75 was applied to the lower levels to resist attack from the pigs.

Urespray F – 75

Urespray F – 75 hybrid polyurea is an exciting new development for agricultural applications. It has outstanding strength and flexibility and is highly resistant to chemical attack. It can be used in anaerobic methane processing and any areas where high pressure hot washing is required.

Foamseal continue to develop products for the agricultural sector and remain at the front of polyurethane foam technology.
