An insulating panel having at least two parallel sides. Along a first one of the parallel sides there is a multiplicity of male-female elements. On a second side parallel to the first one side, there is a multiplicity of female-male elements sized and proportioned for engaging the corresponding elements of another similar insulating panel abutted in side-to-side relationship thereto. Such multiplicities of male and female elements are engageable in a tight fit relation to cooperate in between said abutted panels as to produce a homogeneous force distribution along the side of adjacent panels and thereby to increase the effective shearing strength of such insulating panels.

Why it's free to use
- Filed October 30, 1990 and granted April 30, 1996. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 30, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 30, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
