Metal Roof Condensation Control

If you are heating or cooling a building adding insulation would certainly be a good idea.

Metal roof condensation control.

This is often accomplished using vinyl backed fiberglass insulation to prevent humid air from coming into contact with the cooler metal roof which may be at or below the dew point. Condenstop is an effective affordable solution to prevent condensation on metal roofing panels. Insulate and try to keep from reaching the dew point. Check for short circuits that may be causing moisture such as ceiling fans unsealed light fixtures and vent.

When the temperature of the roof is lower than the air inside the extra moisture in the air condenses on the underneath of the roof. Oftentimes people will insulate their metal roof with vinyl backed fiberglass insulation to prevent humid air from coming into contact with the cooler metal roof which may be at or below the dew point. Environmental building regulations have increased air tightness with a consequent increase in the risk of condensation. Then as the temperature inside and outside equalise the moisture is released.

Inspect the house by looking for vents that flow into the attic such as bathroom and kitchen exhaust fans. The final method of stoppoing a metal roof sweating is to bond an anti condensation layer on to the underside of the roof. While it s not a good insulator condenstop is the hottest product in the market in recent years. Drip stop an internationally patented ccm condensation control membrane is pre applied to our pbr imperial rib and retro r metal panels.

Line the attic. At night the thin metal in the roof quickly cools down. When then environment outside becomes cooler i e. No drips are formed.

When temperature and humidity conditions reach dew point moisture can condense on the underside of metal roofing and potentially cause water damage to the inside of your building. Traditionally condensation is managed by insulating the metal roof so that the panel temperature never reaches the dew point. Add a preinstalled membrane to absorb and release the condensation as it forms with the natural weather cycle. The microsphere technology is a synthetic non woven fleece based on polyester fibers that is applied during the roll forming process saving labor costs.
