Open the CIPO recordAbstract From the Canadian patent
A building panelling system employs insulative boards preferably having a glass fibre core and an outer protective covering on one face surface. The covering rounds the corners of opposed edges of each panel to stiffen them and the panels are, in one variant, installed with their covered sides juxtaposed. A series of adjacent panels are contained between fixed channels that allow the panels to be slip-fitted into place to form a continuous wall. These channels may also be used to provide corner details.

Why it's free to use
- Filed September 10, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 10, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 10, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
