    RTICA Insulation Gains Contractor Approval In Field Installation Trials.

Stoney Creek, Ontario (June 4, 2001): Rtica Inc. announces the successful
completion of attic installation tests for its RTICA  brand insulation in
blowing wool form.  The tests were conducted by certified industry contractors.

"We are delighted with the results", says Warren Arseneau, President.  "RTICA
far exceeded our expectations and those of our customers in all criteria tested.
With this accomplished, we have building code approval, now in its final stages,
as the only other industry prerequisite to our shipping product commercially."

On the building code front, RTICA loose fill insulation has evaluations pending
at the Canadian Centre for Construction Materials (CCMC), Building Officials and
Code Administrators International (BOCA), The International Conference of
Building Code Officials (ICBO) and The Southern Building Code Congress
International SBCCI.  RTICA has also passed the Technical Review of the
California Bureau of Home Furnishings and Thermal Insulation (CBHF), enabling
the company to apply for a license to sell its insulation products in
California.  RTICA blowing insulation currently meets the Technical Guide
requirements for CCMC and published standards in applicable sections of ASTM C
764, Mineral Fiber Loose-Fill Insulation and ASTM C 739, Cellulose Fiber
Loose-Fill Insulation. And as measured against Fire Hazard Classification,
Canada Underwriters Laboratory S102.2, RTICA exhibits average Flame Spread
Indexes and Smoke Developed Indexes well below the levels required for loose
fill insulation in Canada and the United States. All test results are based on
independent tests results from accredited laboratories.

RTICA  is a highly efficient insulation produced by a proprietary plastic
technology that utilizes recycled or virgin polymers.  A lack of dust and itch
also promotes a healthier workplace when compared to fiberglass and other
mineral products.  Its pre-eminence as a thermal barrier, particularly in homes,
positions RTICA  as a leading solution to an intensifying global quest for
energy conservation.

Rtica Inc. is a subsidiary of Rtica Corporation, a public company traded on the
CDNX exchange under the symbol RTN.  There are approximately 34,052,636 shares
outstanding.  The corporate website can be found at www.rtica.com
