This invention relates to constructional ma

plastic substance.

structional units adapted to be employed as a Á`V`iibrous material and aqueous dispersion of as
weatherproof covering that closely simulates a phalt. Material of this character in which the

Waterproof thermoplastic ingredient is incorpor

Heretofore, for this purpose it has been pro
or boards 1s readily susceptible to shaping as by
ated units, each unit con
rip having narrow spaced
strips of roofing ma
adhesively secured
thereto. These strips terial
are expensive to manu
facture because the pro per spacing and cementing
of the narrow strips t o the base is a time con
` suming and tedious ta
sk. Moreover, when strips
of this nature are laid on th'e side Walls of a
20 building, the -structure is subject, under the ac
tion of the weather, to the tendency towards
moulding or embossing operations. According to
the constructional unit or strip is of general rec- .
tangrular shape with upper and lower edges 4|
and 42 respectively and side edges43 and 44. The
strip is provided with raised substantially rec 20
tangular areas 45 bordered along their upper
edges by a' horizontal depression 46; the upper ex
tremity of which is space d
closely simulate a brick, stone or other like Wall,
and are not subject to delamination when ex
posed to the weather._
Another object of my invention resides in the
novel manner ofl procedure for manufacturing
the constructional units.
