Attic insulation helps to reduce energy costs, increase soundproofing and improve overall home comfort. Insulation can be installed as a DIY weekend project or by professional installers. However, before beginning renovations on an attic make sure the air barrier is intact to prevent moisture problems and thermal bridging.
The type of insulation you choose will depend on several factors, including the climate in which you live, your home’s age and the amount of heat it loses through the attic. If you’re unsure about what type of insulation to install, an attic audit can help.
The Long-Term Value of Attic Insulation – Energy Solutions Explains
Fiberglass batt or roll insulation is a common, budget-friendly choice for attics. It comes in pre-cut batts or long rolls that can be easily slipped between the joists and trusses in your attic. It’s also effective at resisting heat flow and is safe to handle. However, it absorbs water and can take a long time to dry, making it susceptible to mold and mildew growth.
Reflective barrier insulation (also known as radiant barriers) is typically backed by foil, making it effective at reducing the transfer of heat through your roof. It’s also relatively lightweight and easy to install. However, it primarily addresses radiant heat and may not be sufficient as the sole insulation method in all climates.
Rigid foam insulation boards like EPS and XPS provide an excellent R-value per inch, are resistant to moisture and can be used in new construction or major attic renovations. It’s important to note that these insulation materials require a continuous air barrier and must be used in conjunction with other insulation methods.
