In its broadest aspects the invention provides, for an
opening in a structure, a liner comprising a member de?n
ing a closed area and made of ?exible material of chan

wardly, said member being prefabricated for the particular
size and shape of the opening for which it is intended, and
being of such dimensions that the limbs of the channel
1 acts as an insulating air space sealed off from the atmos
contraction in response to variation in the surrounding
conditions by virtue of the ?exibility of the liner 1 and
the spacing of channel base 5 slightly inwards of the edges
of opening 6.
It will be manifest that various modi?cations may be
envisaged without departing from the scope of the present
invention. For example, where only a single window con
will overlap the structure around the opening and the base
struction is necessary the liner may be positioned as de
