Radiant Barrier & Insulation
We recommend R-60 or 24"
When adding additional insulation, you do not have to use the same type of insulation that currently exists in your attic. You can add loose fill on top of fiberglass batts or blankets, and vice-versa. If you use fiberglass over loose fill, make sure the fiberglass batt has no paper or foil backing; it needs to be “unfaced.” If you choose to add loose fill, it may be wise to hire a professional, as the application requires the use of a blowing machine.
SOLAR ATTIC FANS
A note about Natural Attic Ventilation
At first it may seem odd to add insulation for warmth and then purposely allow air to enter the attic through vents, but this combination is the key to a durable and energy-effcient home. Here's why: in the winter, allowing a natural flow of out door air to ventilate the attichelps keep it cold, which reduces the potential for ice damming( snow that melts off a roof from an attic that is warm and then re-freezes at the gutters, causing an ice dam that can damage the roof). Proper insulation and air sealing also keeps attics cold in winter by blocking the entry of heat and moist air from below. In the summer, natural air flow in a well-vented attic moves super-heated air out of the attic, propecting roof shingles and removing moisture. The insulation will resist heat heat transfer into the house. The most common mistake homeowners make when installing insulation is to block the flow of air at the eves. NEVER COVER ATTIC SOFFIT VENTS WITH INSULATION-use rather vents and sofits vents to maintain airflow
Attic Ventilation Turbine Fans
Attic fans are intended to cool hot attics by drawing in cooler outside air from attic vents (soffit and gable) and pushing hot air to the outside. However, if your attic has blocked soffit vents and is not well-sealed from the rest of the house, attic fans will suck cool conditioned air up out of the house and into the attic. This will use more energy and make your air conditioner work harder, which will increase your summer utility bill. You don’t want your unfinished attic cooled by your air conditioner. To prevent this, follow the air sealing and insulation strategies in this guide and make sure the attic is well-ventilated using passive vents and natural air flow.
