Insulation Baffles Cardboard
SmartBaffle can be used to protect your crawlspace from cold air and keep it well insulated. It's a custom-cut, one-piece baffle and can be installed underneath your raised floors. It takes only a few minutes to install and can easily be done by a DIYer. SmartBaffle provides years of clean attic ventilation and airflow if it's installed correctly. SmartBaffle can simply be installed using a utility knife. For thin baffles made of polyfoil, you can also attach them to your joists. It's simple.
When intake vents are blocked, the amount of fresh air needed to properly ventilate your attic is impaired. This can lead to heat buildup in the attic and can allow moisture build-up in winter. While it may seem counterintuitive, you do not want heat to build up in your attic in winter. A hot attic can lead to ice dams which can be very destructive.
Ventilation is essential for any roof with an attic. It allows airflow through the attic to exit the roof vents which manage heat and moisture. Baffles can be installed between roof rafters and beams to prevent insulation from clogging the attic space. To ensure adequate airflow, baffles should be placed in the attic where there is an intake vent (soffit ventilation). However, the devil is in how it's done. The installation guide can be helpful in ensuring that baffles are properly installed.
