                  ElkCorp Comments on BMCA Proposal


    DALLAS--(BUSINESS WIRE)--Nov. 16, 2006--ElkCorp (NYSE:ELK) today
issued the statement below in response to BMCA's amended 13D filing
and letter in which BMCA proposes to acquire ElkCorp for $35 per share
in cash. As announced on November 6, ElkCorp's Board of Directors is
engaged in a review of the Company's strategic alternatives and has
retained UBS Investment Bank to assist in this process.

    Statement

    "The Board is firmly committed to a fair process that will yield
the best result for all shareholders and the Company, and will
evaluate and consider BMCA's proposal in the context of the overall
process and all other proposals received.

    "Regarding BMCA's unwillingness to execute a customary
confidentiality and standstill agreement, several parties have already
signed our form agreement and are actively participating in our
process, including by submitting indications of interest. We have
simply requested that BMCA do likewise and participate on a fair and
even basis with other interested parties. A number of the assertions
in BMCA's letter are simply incorrect. Among other things, BMCA
indicated no willingness to compromise on the terms of the agreement,
insisting instead on preferential treatment not justified by their
offer.

    "We continue to invite BMCA's participation in our process on a
basis that enhances rather than reduces the likelihood of achieving
the best possible result for our shareholders."

    As previously disclosed, the Company has not set a definitive
timetable for completion of its evaluation and further there can be no
assurances that the evaluation process will result in any transaction.
