Why a laid scrim

Neither woven nor knitted: the threads are laid and bonded at every crossing point – the grid stays dimensionally stable.

Strength where it is needed: warp and diagonal threads distribute the load and stop tears from spreading.

Tailor-made: yarn, spacing, width and binder matched to your product and line, from sample to series production.
