Patent ID: 7797891

Claim:
A window frame assembly insulation and sealing arrangement, for weather-tight insertion into an opening of a wall of a building comprising: an elongated block of flexible foam material having a first or inner side and a second or outer side, said first side matable against a window frame assembly, wherein said first side of said block has at least one window frame receiving channel therein to engagably mate with an outwardly facing portion of said window frame assembly; a foam air fin unitary with said enlongated block, said air fin comprising an elongated flange of flexible foam material, said air fin and said elongated block defining an elongated compression member receiving-channel therebetween, wherein said second or outer side of said block and said air fin lie in parallel planes and are compressed against said opening of said wall; and a compression rod arranged within said elongated compression member receiving-channel between said air fin and said enlongated block, to provide a compressive force upon said air fin and said elongated block of foam by said compression rod, so as to sealingly compressably force said air fin against a wall opening in a building, and wherein said compression rod is of greater thickness than said receiving channel is wide, when said air fin and said enlongated block are uncompressed.
