Insulating the floor is standard for an unfinished attic space. The exception to this rule occurs when families choose to convert an unfinished attic space into something useful or livable. Loose fill or batt insulation is usually installed in the attic. Loose-fill insulation is usually cheaper to install than batt insulation and provides better coverage when installed correctly. https://www.dakisolatiewijzer.be
See more about different types of insulation. The main difficulty with this technique is sealing the barrier to the top plate of the wall, especially at the eaves where there is little room for maneuver. This area must be well sealed. Spray foam or rigid board insulation can help bridge the gap in this area.
Cut a rigid sheet to fit between the ceiling joists and extend from the top sheet of the exterior wall to the attic. A second piece of rigid insulation, installed vertically, connects the polyethylene to the horizontal rigid sheet. Carefully wide any seams or seams between materials. Extending two-piece spray foam kits (or the service of a spray foam company) are also great for sealing areas around joists and planks.
As mentioned earlier, attic ceiling insulation is easier and cheaper than roof insulation. Installing (or adding) insulation to the ceiling plane is quite simple. Although, if the attic floor is insulated, a new vent can easily be cut into the roof deck without removing or interfering with the insulation. Optimal foundation insulation materials and placement vary by climate, so consult a local insulation professional when planning a new home.
