Metal Roof Condensation Control

Environmental building regulations have increased air tightness with a consequent increase in the risk of condensation.

Metal roof condensation control.

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. Line the attic. While it s not a good insulator condenstop is the hottest product in the market in recent years. Insulate and try to keep from reaching the dew point.

When then environment outside becomes cooler i e. 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. Moisture control materials such as roofaquaguard 3d offers an easy application that can quickly be applied directly to the roof deck prior to installation of the metal roof panels. Drip stop an internationally patented ccm condensation control membrane is pre applied to our pbr imperial rib and retro r metal panels.

Traditionally we ve insulated the roof panel to try and keep the temperature on the panel from reaching the dew point. The result is the roof sweating and dripping water all over your precious stuff.

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. The final method of stoppoing a metal roof sweating is to bond an anti condensation layer on to the underside of the roof. When condensation starts to form on the underside of the roof it is absorbed by the fleece material. How to stop condensation on a metal roof step 1.

Condenstop is an effective affordable solution to prevent condensation on metal roofing panels. At night the thin metal in the roof quickly cools down. Then as the temperature inside and outside equalise the moisture is released. Add a preinstalled membrane to absorb and release the condensation as it forms with the natural weather cycle.

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. Check for short circuits that may be causing moisture such as ceiling fans unsealed light fixtures and vent. Inspect the house by looking for vents that flow into the attic such as bathroom and kitchen exhaust fans.
