Abstract
Rigid foam-core construction underlayment is formed to have one broad side covered by a flexible substrate that carries a series of spaced-apart, discrete regions (such as islands or spaced lanes) of resin, each resin region carrying a respective field of male touch fastener elements extending away from the substrate and exposed for engagement, such as by fibers on an inner surface of exterior construction material, such as a roofing membrane.
Claims8
A construction underlayment comprising
- a rigid foam board having two broadest sides defining a thickness therebetween;
- and
- a facing comprising a flexible substrate bonded across one of the broadest board sides and carrying a series of spaced-apart, discrete regions of resin extending away from the foam board, each resin region carrying a respective field of male touch fastener elements extending away from the substrate and exposed for engagement;
- wherein each region is a continuous lane of resin, the series of discrete regions comprising parallel lanes of resin defining longitudinally continuous gaps therebetween;
- and
- wherein each lane defines multiple bend points spaced-apart along its length, at which bend points the lane has a lower resistance to bending than at points between the bend points, each bend point defining a groove extending laterally along a width of the lane.
