Item 2   Date of Material Change

September 15, 2006

Item 3   News Release

A press release was issued on September 15, 2006 in Toronto, Ontario and
disseminated across Canada through the facilities of Canada Newswire.

Item 4   Summary of Material Change

On September 15, 2006, the Company announced its intention to divest of
additional non-core businesses and assets. The non-core businesses include Royal
Dynamics, which is an injection molder of building products, as well as certain
other business units. The assets being divested of include excess real estate
that is being vacated as a result of the Company's manufacturing operation
consolidation program.

The Company expects to generate cash proceeds in the range of $30 to $40 million
from these divestitures. In a previous news release on August 15, 2006, the
Company indicated that it expects to generate total proceeds from divestitures
of $200 to $260 million in 2006. In the event of successful execution of the
foregoing divestiture decisions, the Company can achieve proceeds in the high
end of its range of expectations. To date, the Company has generated proceeds of
approximately $190 million.

During the third or fourth quarters of 2006, the Company intends to record a
write down in the range of $65 to $75 million in connection with the additional
divestitures. This write down represents the net of gains on some assets and
losses on others.

The September 15, 2006 announcements are consistent with the Company`s
previously announced four-part Management Improvement Plan, embarked upon by the
Company in mid 2005.

The Company advised that it continues to take actions to reduce its
manufacturing/warehouse footprint, with one million square feet of space listed
for sale in recent weeks. Should the Company be successful in selling this real
estate prior to year-end, it would exceed its range of expected proceeds.

The Company also advised that it recently concluded the sale of its window
coverings operations in the Netherlands and Brazil.




On August 4, 2006 the Company's shareholders approved Georgia Gulf's proposal to
acquire all of its outstanding shares of the Company for C$13.00 in cash per
share pursuit to an arrangement agreement that was publicly announced on June 9,
2006. The Company confirmed that it continues working to conclude Georgia Gulf's
previously announced acquisition at Royal Group.
