Insulation Baffles Installation
Other baffles are designed for insulation alone and don't take into account that it often falls out. When installed, it should be loose-fill insulation because this type fills all gaps to maximize its potential, reduce moisture, decrease stale air, and allow air to flow (air circulation) more effectively. Those who install insulation without installing baffles could end up with areas that are either too full or too empty, meaning there isn't enough insulation in the rafters spacing. By installing baffles, you can ensure rafter spaces are filled completely while preventing insulation from filling unwanted areas of your attic or crawlspace.
Baffles work by preventing the flow or fluids of gases, liquids and air. Attic Air claims the baffles help to maintain proper airflow, and they prevent insulation from getting in the way of vents. They can be made out of PVC, rigid waterproof foam, cardboard or plastic. They are installed on the attic ceilings between the rafters, at the places where the attic roof meets your attic flooring.
Depending on your attic's vent space, you'll need to install several baffles. For example, if you have a 150-square-foot attic, you'll need one per square-foot of rafter vent space. You should also consult an expert before doing the installation. Having the right ventilation is crucial for keeping a house cool in the winter and warm in the summer. Without proper ventilation, the humidity that builds up in the attic can rot wood and structural components. It also can cause ice dams to form, which is not good for the roof. Installing baffles will ensure that condensation will not form on your roof.
