Building Envelope Solutions (BES) manufactures and installs weatherization products for various building types and projects. While various types of spray-foam insulation and caulking are used for gaps, cracks, holes, and roof level changes to the building, BES weatherization stripping and sweeps are applied to doors as an all-weather compression seal to minimize the flow of uncontrolled air.

Windows are also factored in during audits; BES has many energy-saving options to correct inefficiencies such as BES Therma-pane inserts and Window Film. Certain projects require complete window replacement, therefor BES offers various window replacement options, framing, and masonry.

Implementation of these products improves overall building performance by reducing energy costs, while acting as an amplified barrier to rodents, insects, and other pests.
