About Proper Attic Ventilation and Insulation
Palomo Insulation attic that’s well ventilated inhibits heat transfer between the attic and living spaces below, keeping your home cooler on hot summer days and warmer on cold winter nights. It also reduces moisture in the attic that can cause mold and rot. In addition, it prevents ice dams and other roof problems in cold climates and keeps your home’s energy bills lower.
The key to a well-ventilated attic is a balance of intake and exhaust ventilation. Intake vents are placed along the eaves and soffits, allowing cool air to enter the attic through ridge vents or roof louvers and suck hot air out through exhaust vents near the peak of the attic space. To be effective, the vents must be properly sized and positioned to create constant air movement throughout the attic. This movement is created either by natural stack and wind effect or by mechanical ventilation involving fans.
One of the most common issues caused by a poorly ventilated attic is attic mold, which results from moist air rising from living spaces below and condensing in the attic. Moisture and heat combine to form a breeding ground for mold that can damage the shingles over time. Moreover, mold can pose serious health risks to the home’s occupants and contaminate living spaces below.
How Attic Insulation for Hot Climates Lowers Energy Costs
Another issue caused by inadequate attic ventilation is ice dams, which occur when the built-up heat in a poorly vented attic melts snow on the roof and then refreezes over the eaves, forming a puddle that can soak insulation and fascia boards, corrode shingle sheathing, leak into living spaces below, and damage exterior woodwork. Proper attic ventilation and insulation, including properly sealed gaps and proper shingle insulation, prevents the formation of ice dams and other winter problems.
