Attic ventilation theory.

In mixed climates ventilation serves either role depending on the season. Because the roof isn t in play here it doesn t matter how many hips valleys dormers or gables there are. Having attic ventilation doesn t ensure the moisture gets ventilated away before it condenses on your expensive roof and wall surfaces. 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 in the winter. Attic ventilation is a process of creating air circulation in the home. Foam tech creates superior insulation and environmental control solutions by installing safe cost effective and environmentally friendly polyurethane foams. An attic fan can be gable mounted or roof mounted.

However in pursuit of attic ventilation some people choose to install attic power ventilators. 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. The same goes for attic ventilation. The theory behind attic ventilation is to give that moisture a place to escape before it causes mold mildew rot or other problems.

Additional vents are required to draw in fresh air as the hot air is exhausted. You would think that venting an attic would be counterintuitive in the winter or cold months. It s essential for reducing moisture and preventing excessive heat. The theory is the same for your attic ventilation system.

In theory these are excellent tools for circulating air in the attic and keeping the attic temperature low. The problem with this design is it is wishful thinking. In theory balancing the venting system is important in order to maintain appropriate air pressure in the attic space. All of these materials are supported by quality assurance testing capabilities that.
