The GWS self-adhesive pins are attached to the plain ductwork
surface with a self-adhesive foam patch, providing spikes to
which thermal insulation can be attached without piercing
the ductwork walls.
Available sets include GWS pins and KLP clips. KNY caps are
sold separately.
A total of 6 to 10 GWS self-adhesive pins are recommended
for a surface area of 1 m2.
