Agricultural Building Insulation

Options available for new construction and to retrofit barns, riding arenas, storage sheds, workshops, and more.

Agri Plus I

Agri Plus is a fine fibred flexible insulation blanket faced with a white reinforced vapour retarder facing. It is installed under the roof sheet on Agricultural Buildings. It is commonly referred to as a Condensation Blanket. It is ideal for use in barns, riding arenas, storage sheds, workshops etc.

All rolls are produced with 2.0” thick with an R7 value. All rolls are 48” inches wide and all the lengths are all custom cut to your specifications.

Bay recommends allowing 1-2’ ft. extra for the lengths of the roof rolls and allow 1’ ft extra for the wall rolls. Each roll is produced with a vapour retarder facing laminated to one side of each roll. A vapour retarder facing effectively limits the amount of moisture that can migrate into the insulation.
