Instructions:

1. Take precaution measures to avoid moisture problem in cathedral ceilings

Problem of moisture in cathedral ceilings may arise due to certain reasons. The traditional methods help in checking moisture problem as they cause the emission of moisture entering into the ventilation area and spreading out of the cavity through the insulation.

2. Easy air flow is possible through old insulation

Fiber glass is the most commonly used insulation material. Such traditional methods help in the movement of air flow easily. Incorporate ventilation and inhibition of moisture penetration were the commonly used method. They are comparatively much cheaper and are very easy to implement.

3. Problems regarding ventilation area

Fiberglass batt insulation is nowadays a commonly seen insulation in most of the houses. But it does have a problem of water beads formation on fibers. That is how ventilation method has developed. It should be noted that ventilation over the insulation may cause excess heat loss by allowing the air movement through the fiber glass which is of low density.

4. Insulation with Kraft faced batts

In order to make the right insulation, it should be cut accordingly. After cutting, press the insulation batts which are placed between the joists. The room should face the Kraft paper. As a safety measure, insulation should be placed 3 inches away from the heat sources.
