The
perfect insulation application for poultry sheds, cattle
and pig buildings, potato and grain stores (refrigerated
& ambient)...
Protects
from the weather with a
"Two in one" application. As this last winter
has shown, valuable crops stored in an uninsulated shed
can be lost to frost and extreme cold . As little as
50mm of spray foam 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 in tact, and without further treatment
or coating. The Class 0 fire rating is achieved through
using a fire resistant foam and two coats of FPC in
either white or grey.

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 foam for
ambient stores, and a minimum of 75mm for refrigerated
stores.
