Product Info - Thermal Fungi & Pest Resistance

Weathershield insulation provides long term protection against wood decay, fungal growth, insects, mice and other vermin.

Weathershield insulation is treated with a carefully controlled blend of borate powders so that the performance requirements of applicable standards are ensured.

A less well known function of these borates is their ability to prevent formation of mold, mildew and wood rot. This unique characteristic of borates is becoming increasingly valuable as the trend toward tighter house construction increases the potential for moisture accumulation within the building envelope.

The construction of tighter houses has often resulted in a higher interior humidity and air pressure differential. These two factors have combined to increase the accumulation of condensation moisture in framing and sheathing components. These developments have created serious concern about structural failure from wood decay.

Hence, it is a considerable interest that field-testing shows the borate of Weathershield insulation has the ability to prevent formation of destructive fungal spores. Furthermore , the fungicidal character of the borate compound also has the advantage of being offensive to insects and vermin that they will avoid contact with cellulose insulation. Therefore, use Weathershield insulation to help prevent problems associated with unwanted pests.
