or corners interrupt the even spacing when this happens small cavities 4 are created in either case though a number of wall spaces opening toward the interior are formed between each adjoining pair of vertical studs after the outer wall material 6 has been installed it is desirable to place insulation in the wall spaces before the inner wall material 7 is installed with this method there is no need to remove part of the inner wall to install the insulation to support the insulation before the inner wall is installed however a support material must be placed where the inner wall will be the support material must keep the insulation material completely back in the wall cavity so that the inner wall may be installed flush against the studs even u00bd inch of bowing of the insulation may mean that the drywall cannot be installed properly further the support material should allow air to escape from the cavity as the insulation material is being blown in this also helps to keep the insulation material from extending outward from the wall cavity to accomplish these goals an air permeable and adhesive permeable u201c cloth u201d material 8 is used to hold the loose fill insulation in position until the inner wall material can be installed the cloth is secured to the studs using a flowable adhesive that can be u201c painted u201d on with a roller the adhesive is painted onto the areas of cloth that overlie the stud face.
