Please contact Brett
Martin for further information on the fire performance of “High impact”
Marvec.
High impact
Marvec
“High impact” Marvec has an impact resistance10 times that of
standard material. Specially formulated by Brett Martin, it combines the light transmission and fire
performance properties of standard material with greatly improved impact
resistance, whilst remaining very cost effective. It is ideal for use in
glazing where there is added risk of damage.
