US Disp. & Acquisition Update

SIG PLC
21 November 2006



                DISPOSAL OF U.S. BUSINESS AND ACQUISITION UPDATE

                             Sale of U.S. Business

SIG plc, the leading supplier of insulation, roofing and commercial interiors
products, announces the disposal of its US business to Grey Mountain Partners.
Proceeds from the sale amount to $51m in cash. This sum is slightly higher than
net asset value, resulting in a small profit on disposal.

David Williams, Chief Executive of SIG, commented, 'Although the US business has
performed extremely well over recent years, our rate of growth and expansion in
the UK, Ireland and Mainland Europe has been such that the US today accounts for
less than 4% of total Group sales.

Given the future opportunities for SIG within the UK, Ireland and Mainland
Europe, our strategy is to concentrate our resources towards these territories.
On this basis, it makes sense for the US business to be allowed to develop
outside the SIG Group'.

Acquisition Update

Within the 2006 Interim Results Announcement released on 12 September 2006, the
company informed shareholders that it had completed 12 acquisitions up to that
date in 2006 with combined annual sales of circa £115m.

Since that date, a further 9 acquisitions have been completed.

These are again broadly spread across the Group's existing business streams and
increase coverage in the UK, Ireland and Poland.

This takes the combined total of acquisitions completed so far in 2006 to 21,
with combined annual sales of circa £210m. Total consideration for these 21
transactions amounts to circa £88m including assumed debt.

Trading

Current trading is in line with expectations, and the Group is confident of
meeting analysts' consensus expectations for 2006.
