Post by: perry f. on September 10, 2014, 09:20:00 PM
Just curious what are the advantages of ULS or UL glass. How do they compare to each other

maybe this will help....

E-glass (ULS) - Tension strength of...152 / compression strength of...111

S-glass (ULZ) - Tension strength of...243 / compression strength of...119

Carbon - Tension strength of...430 / compression strength of...160

ULS glass has scrim and in theory will help keep thin stack limbs (re-curve) from twisting. I have used both and for what is real I can't tell any difference.

Correct ULS is for aiding in no limb twist;      But here lately the UL glass has been the cleaner of the two.  (Less Streaky)
