The Green Property

The most important aspect of attic ventilation is for drying internal moisture which develops during the heating season.  Internal moisture refers to the condensation of more humid interior air when it escapes to cold wall and attic cavities.  Warm air can hold more moisture in vapor form than cold air.  When that warm air cools, it releases the vapor in the form of condensation. When the ventilation in the attic is not sufficient to dry this condensation, a house can experience mildew buildup, wood rot, delamination of subroofs,.  peeling exterior paint, and other problems.

The solar-powered attic fan can also prevent heat build-up.  A hot attic transfers heat into living spaces, which makes both utility bills and temperatures very high.  In colder weather, when heat builds up in an attic, it causes snow to melt and run down at the eaves where it freezes, causing destructive ice damming.  A solution to this is The Solar Star™ Roof Mount VentŪ. It pulls out hot air and moisture from the attic and releases it to the outside.  It will reduce heat build up, reduce air conditioning costs, and prevent ice damming.

Most houses today don't have good ventilation and air exchange.  That brings high humidity levels from everyday activities like showers, laundry and cooking.  The moisture moves through the ceiling towards the roof where it comes in contact with the cold structure.  This causes ice and frost to form, bringing damage to your roof structure.  Also, moisture can saturate insulation and build up fungal decay.  Solar Star™ provides excellent ventilation which greatly reduces damaging condensation, protect insulation from moisture saturation, fight mold and fungal decay, and reduce heating costs.
