Foam Insulation Baffles Between Rafters And Trusses
Installing rafter vents (also known as insulation baffles) to cover your attic floor completely will allow you to insulate the entire area up to the eaves. Your insulation will perform best if it is fully covered and sealed. Rafter vents ensure that the soffit ventilations are clear. Outside air can flow into the attic through the ridge vent, gable, or attic vents. You can attach the rafter ventes to the roof decking directly. Rafter vents are available as 4-foot lengths or in 14-1/2 to 22-1/2 inch widths depending on the rafter spacing. Rafter vents should go in the attic ceiling between your rafters and the point where you meet your attic floor.
A baffle is mainly used for support and stability but it can also be used to keep conditioned air from escaping into the surrounding area. Installing a SmartBaffle in your home will lower the amount of energy you use each month, keep drafts out during cold winter months, and increase your indoor air quality as well. In most cases, insulation is installed with no insulation on the roof deck which allows cold attic air to sink into the insulation anywhere it can. This is a huge source of heat loss and is very expensive. Installing insulation will increase the R-value but also adds a layer of insulation that reduces airflow up through insulation by as much as 75%.
A non-integral baffle is also designed to stop the material from entering into areas it shouldn't. It's made of different types of insulation materials that are held together with a polypropylene web. SmartBaffle is designed to keep insulation where it needs to be while stopping it from entering unwanted areas, such as exterior walls or floors. This device also increases the ability for air to flow and circulate more effectively, creates proper ventilation, and keeps insulation from deteriorating prior to its time so you won't need to worry about purchasing a new system any time soon. In fact, when installed correctly, it can be used for up to 20 years.
