Attic Ventilation Insulation

Good roof ventilation can do this but shingle color sun exposure and insulation are exponentially more important to overall energy efficiency than ventilation.

Attic ventilation insulation.

For most of us the attic is a place to store clothes luggage and old family photos but for energy researchers it s a hot topic of discussion. Can you have too much ventilation in your attic. Lowering the temperature in the attic can help reduce air conditioning energy costs and roof deck temperature optimize the service life of a roof covering and minimize ice damming. Insulation is used in an attic for cross ventilation to minimize potential for moisture accumulation and condensation to help energy savings and moisture control.

The rvk1a steel roof cap kit is an the rvk1a steel roof cap kit is an easy to install vent for ventilation fans bath rec room home gym etc. In the winter warm moist air seeps into the attic from the living space below.

In the last several decades building codes have called for increased attic insulation. That cuts cooling costs and prolongs shingle life.

For the same reason insulation shouldn t touch the roof s underside. The airflow from the soffits to the ridge vent keeps the roof cool and prevents ice dams and the material will block that flow. Attic ventilation serves two main functions.
