Agricultural Insulation

Agricultural Sprayed foam insulation – the perfect insulation application for poultry sheds, cattle, pig buildings, potato and grain stores (refrigerated & ambient)…

Websters Insulation Ltd has over 35 years of experience in the application of polyurethane spray foam insulation to agricultural buildings across the UK.

Spray Foam Insulation for any type of agricultural outbuilding will provide perfect insulation for cattle and grain. The effects of the insulation are felt immediately and is a great way of maintaining a constant temperature. The insulation also does a good job of weatherproofing the building as well as curbing it from any condensation.

Protects from the weather with a “two in one” application. As these last few winters have shown, valuable crops stored in an uninsulated shed can be lost to frost and extreme cold. As little as 50mm of sprayed foam insulation can protect stored food items and stabilise the temperature all year round. When applied externally to a leaky roof it can insulate and weatherproof in one, therefore extending the life of the building.

Fire resistance

Our system is designed to give up to class zero fire rating where required (Pirthane), though the Webtherm spray-applied Polyurethane foams have a standard CLASS 1* surface spread of flame rating when tested according to B.S.476 part 7. The class 1 rating is achieved on the naked foam with the spray applied finish intact and without further treatment or coating. The Class 0 fire rating is achieved by using a fire-resistant sprayed foam insulation and two coats of FPC in either white or grey.

The Benefits

Typical Specification

U-Values The u-values in the table below are based on the foam being applied to the underside of 8mm thick big 6 profile asbestos sheeting to a typical potato store. Websters recommend a minimum of 50mm Webtherm sprayed foam insulation for ambient stores and a minimum of 75mm for refrigerated stores.
