ADO Products

This website features ADO Products. ADO products has long been recognized as a leading supplier for the insulation trade. Its insulation products are better installed by insulation and building contractors as application is not for a regular do-it-yourselfer.  ADO Products offer accessories that help properly ventilate a home. Insulation is not just blowing-in loose-fill cellulose or the laying out of thermal batts. Insulation and ventilation are in tandem to produce a well-insulated and ventilated structure.

Attic Ventilation

If you want a cooler attic during the hot summer months and a drier and warmer attic in the cold months, proper ventilation is a priority. The best insulation product will prove useless if your attic is not fitted with proper ventilation.  A properly ventilated attic will exhaust overheated air and take in cooler outside air during the summer months. In the winter, humid and moist air is exhausted from the attic. A properly ventilated attic/roof will also extend the life of roof shingles and insulation framing, prevent ice dams.

ADO Ventilating Products

There are two types of ventilating system product offered by ADO – intake vents and exhaust vents. As per ADO instruction, intake vents are best located at sides of the house to maximize its function. Exhaust vents ideally should be located at the highest part possible and spaced evenly for maximizing air flow. Intake vents are installed in soffit, under eaves and rafter vents. Exhaust vents will be most effective when placed at ridges, roof, gables vents and turbines.

• Durovent

This is foam attic ventilation that is best used for new construction.  Each span will fit 16 inches to 24 inches truss or rafter spacing. One span or channel of Durovent is recommended for each truss or rafter cavity. Dimension of one Durovent channel is 48”x22” with an air channel depth of 1.4 inches.  Durovent ventilation channel is stapled over the top plate of rafters or trusses. When done, insulation is applied against the ventilation channel.

• ProVent

Provent is best used for older homes with existing insulation. The plastic material is stronger than foam and can be installed over existing insulated attics with no trouble. Retrofit projects are usually tight because of existing insulation. More often than not, there is a need to “push” the ventilation channel over existing attic insulation.  Provent is designed to bear such force better than a foam ventilation channel. Provent has 2 models to each fit 16” and 24” roof joist or rafter spacing.

• Windblock

Windblock can prevent any wind-driven moisture and cold air from entering the rafter vent and the top wall. This will prevent undue energy loss in the attic. This will also stop mold growth due to moisture.  The Windblock can be effectively use for both new and old installations. Install one windblock per rafter or roof joist cavity.
