Insulating a barn roof is very similar to insulating any other kind of building. However, barns are colder than other buildings and may require more insulation. Depending on the type of barn, your requirements may vary. If it is a barn for keeping animals in, insulation is much more important. Aside from that, the process of installing the insulation is much like installing insulation in a house roof. In a barn, it is important to keep any insulation materials out of the reach of animals, especially animals which are likely to eat the insulation or damage it in any other way.

Step 1-Installing the Baffles

Baffles are easy to find in any DIY store. These have to be installed in all the areas where the insulation needs to be held firmly in place. This is especially important in areas where the insulation meets the ceiling joists and the roof rafters. These baffles need to be stapled in place in every opening between the roof’s rafters.

Step 2-Working around Any Fixtures

You will also need to take into consideration any fixtures, such as electrical supplies or light fittings. Insulation needs to be kept a safe distance away from these. This is especially the case with light fittings, since light fittings can heat up and cause the risk of fire if the insulation is too nearby. Keep the installation a safe distance away, typically several inches. You should fix the pieces of wood that you purchased around these fixtures, creating a box. This box will act as a wall, protecting the fixtures and allowing you to place insulation more thoroughly.

Step 3-Laying the Plastic Sheeting

The plastic sheeting should be laid carefully against the inside of the roof between the eaves. Do this where you intend to install insulation materials, as this will create a barrier for any water vapor. It will prevent any moisture buildup from damaging the insulation. These plastic sheets should be fixed in place using the staple gun.

Step 4-Installing the Insulation

Fiberglass insulation is available in just about any home improvement store. You should cut it to fit appropriately, having measured it accurately. This insulation is to be tucked firmly into the spaces between the ceiling joists. Any gaps will defeat the purpose of having insulation in the first place. When you cut it, it is always better to allow for an extra couple of inches in width. However, the installation should not be compacted too much, since this will also have a negative effect on insulation. Lay this insulation material long ways between the roof joists and fix it into the roof using appropriate tools. The right tools should come with the package.

Step 5-Covering the Insulation

Finally, it is a good idea to cover the fiberglass insulation to both protect and hide it. You can use light wooden paneling to do this, which can be stapled or nailed in place.
