Abstract
Abstract A baffle for retaining insulation between the base plate and the floor of a structure to provide insulation between adjacent floor joists. The baffle is a flat sheet member having foldable bottom and top flanges and foldable side flanges. The flanges are connected to the body with fold or crease lines which aid in the folding of the flanges to accommodate the size of the openings between adjacent floor joists, the ceiling and the top of the basement wall. The body has a circular crease with a plurality of flaps. The flaps can be bent to provide an opening into the space behind the baffle. The opening is used to fill the space with insulation material.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
146 words
A baffle locatable between a base plate on top of a basement wall, floor and floor joists supported on the base plate of a structure for retaining insulation material in the space between adjacent floor joists and above the base plate comprising: a generally flat body having a top portion, a bottom portion and side portions, said body having a size to close the space between base plate, floor, and adjacent floor joists, said body having means for providing an opening through the body whereby insulation material can be placed behind the body to fill the space behind the body, a first flange movably joined to the top portion engageable with the floor, a bottom flange movably joined to the bottom portion locatable adjacent the base plate, and side flanges movably joined to the side portions engageable with adjacent floor joists and above the base plate.
