Should Wall Insulation Touch The Floor

Hi there i m remodeling my home out in austin where the insulation was removed to address pest and mold issues.

Should wall insulation touch the floor. That s because the paper contains a layer of asphalt adhesive which prevents water vapor from passing through it. Regardless of whether fiberglass insulation is installed in a wall attic or crawlspace. Avoid covering the floor with impermeable insulation materials or rubber backed carpets as they ll trap moisture. 2 exterior walls are now stripped from the interior to the concrete surface was more practical to replace vs.

For the same reason insulation shouldn t touch the roof s underside. Patch drywall after. Basement walls should be insulated with non water sensitive insulation that prevents interior air from contacting cold basement surfaces the concrete structural elements and the rim joist framing. The airflow from the soffits to the ridge vent keeps the roof cool and prevents ice dams and the material will block that flow.

Looking for advice on insulating treating interior walls in a split level kitchen where half of the wall is in ground and the other above. Covering up the soffit vents with loose fill or batts which can happen if you stuff insulation along the eaves is a huge no no. Allowing interior air that is usually full of moisture especially in the humid summer months to touch cold surfaces will cause condensation and wetting rather than the desired drying. Original walls were brick with concrete block kraft tar paper on interior side 3 4 furring strips topped with 3 4 plaster.

I m looking to put new drywall up but i wanted to know if it was possible not to have a gap between the drywall and the floor as my preference is to not use trim on this project.
