Attic Ventilation Theory

We have the capabilities to spray and inject a variety of foam systems to achieve a high r value while providing both effective vapor and air barriers.

Attic ventilation theory.

An attic fan can be gable mounted or roof mounted. While heat migrates in the summer because your attic is acting as a giant pressure cooker in the winter the attic space is colder allowing more room. A key benefit of venting the attic is that the approach is the same regardless of how creative your architect got with the roof. Additional vents are required to draw in fresh air as the hot air is exhausted.

The theory behind attic ventilation is to give that moisture a place to escape before it causes mold mildew rot or other problems. In theory balancing the venting system is important in order to maintain appropriate air pressure in the attic space. It s essential for reducing moisture and preventing excessive heat. In mixed climates ventilation serves either role depending on the season.

You would think that venting an attic would be counterintuitive in the winter or cold months. A thermostat is used to automatically turn the fan off and on while sometimes a manual switch is used. Attic ventilation in the winter. Having attic ventilation doesn t ensure the moisture gets ventilated away before it condenses on your expensive roof and wall surfaces.

A powered attic ventilator or attic fan is a ventilation fan which regulates the heat level of a building s attic by exhausting hot air.

However in pursuit of attic ventilation some people choose to install attic power ventilators. Learn here about ventilation processes products common problems solutions. Foam tech creates superior insulation and environmental control solutions by installing safe cost effective and environmentally friendly polyurethane foams. The theory is the same for your attic ventilation system.
