Sorry for another insulation question, but I couldn't find the answers after searching this site.
Our house has an insulated ceiling and plywood decking installed on the floor in the attic. (In other words, the attic floor is insulated.) The rafters are not insulated and the house has a slate roof... so the attic breathes some but not much. The house has no eaves, so there are no soffits or soffit vents. In fact there is no attic ventilation of any kind. The house has gable ends.
We need to ventilate the attic, probably through the gable ends.
1. What is the best way to vent the attic?
2. Should we use a fan?
3. Where should the fan be located?
4. Should the fan blow into or out of the attic?
5. We had some ice damming this year (in Maryland). In addition to a summer setting, is there some type of thermostat setting that helps prevent ice damming?
6. We want to be able to store boxes & stuff in the attic. Should we insulate the rafters? Would this help with ice damming?
Sorry for all the questions and thanks in advance! --Dawn
