Abstract
Abstract Proposed is a burl foil that can be installed as insulation in shed-like buildings, in particular greenhouses, where a Jalousie-like movement of the burl foil from an at-rest position into a use position is said to be possible, without that the required space for stacking the burl foil in the at-rest position be too large. Additionally proposed are attachment means for the burl foil to drawing means or wire ropes that are embodied as simply structured, commercially producible clamping parts that can also be installed by lay persons on any whatever burl foils.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
184 words
Insulation adapted for use in a greenhouse-type building, said building having a side, said insulation including: a plurality of multiple layer burl foil strip sections disposed along said side of said building, each burl foil strip section having a top and a bottom and constructed to be folded at substantially equidistant intervals creating pleated regions in said section substantially normal to a first direction and to second reverse direction of section movement, each said pleated region including flange means for reinforcing said pleated section region, said flange means including welded cross piece members; each said pleated region formed by joining two adjacent burl foil strip sections at their respective said bottoms with one of said crossmembers, adjacent pleated regions being joined together at the respective said tops of said burl foil strip sections with one of said crossmembers; drawing means attached to each of said sections adjacent said side of said building for moving said sections in a first direction and then in a reverse second direction along said side; and attachment means for operatively securing said foil strip sections to said drawing means.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
20 words
Insulation according to claim 1 wherein a portion of each said pleated region supports a portion of said attachment means.
Claim 4
Dependent Claim
83 words
Insulation according to claim 2 wherein said attachment means includes a hook portion and a clamp portion, said clamp portion is secured to said portion of said pleated region; said hook portion includes a foot end, said foot end having a hole plate with spaced apart openings therein, and a pin plate having a plurality of spaced-apart pins projecting therefrom, said pins are constructed to be plugged into said openings in said hole plate whereby said pins are anchored in said hole plate.
Claim 5
Dependent Claim
31 words
Insulation according to claim 3 wherein each said attachment means further includes a pair of spaced-apart connecting brackets, each said bracket is secured intermediate said pin plate and said hole plate.
Claim 6
Dependent Claim
50 words
Insulation according to claim 4 wherein each said connecting bracket includes a notched portion whereby said bracket can be inclined to allow said hole plate to be aligned with said pin plate, each said hook portion further includes attachment button means for connecting said attachment means to said drawing means.
Claim 7
Dependent Claim
27 words
Insulation according to claim 1 further including a coating applied to each said foil strip section whereby the degree of insulation provided each said section is increased.
Claim 8
Dependent Claim
