with Atrium Companies Inc. to acquire the extrusion assets of Atrium's
subsidiary, Thermal Industries, Inc. located in Pittsburgh, Pennsylvania and

Under the terms of the supply agreement, Royal will supply approximately US$7
million per year of extruded profiles to Thermal's fabrication plants located
in Pennsylvania. The term of the supply agreement is for a period expiring

States and Canada. The relocation of extrusion assets will commence October 1,
2001 and is expected to be completed by December 31, 2001, with supply of
extrusions commencing as certain of the purchased assets are made operational.

Vic De Zen, Royal's Chairman, President and C.E.O., noted that, "folding the
extrusion assets of Thermal into Royal's existing manufacturing plants will
improve plant efficiencies, leverage current investments in manufacturing
infrastructure and improve returns on invested capital". Jeff L. Hull,

"recognizes that Royal's extensive vertical integration enables it to
manufacture superior quality profiles and rapidly respond to changing customer
needs". He also noted that the agreements "allow Atrium to focus on its core
competancy of window fabrication". Mr. De Zen added that the transaction,
"illustrates the window fabrication industry's broadening appreciation for
