Can anyone tell me the difference between core-tuff glass and uni-weft? Have always used the uni weft but looking to start buying from different supplier..and what they sale is core-tuff. Is there much difference or what is the difference?...Thanks
Core tuff is unidirectional laminate glass.
Uniweft ids unidirectional glass, but has a cross latch of glass within (imagine a netting impregneted within). This cross directional glass should help with stability, but if used in overlays it will show through and does not look all that great.
Thus use core-tuff for overlays and stripes and uniweft in a limb core if you need cross directional support.
I use stablecore quite a bit (similar to uniweft, but it is carbon and only .016 thick.
