PultTuded w i n d o w s for the high life Pultruded fibre reinforced plastic (FRP) window frames have considerable advantages over other materials f o r u s e in h i g h rise buildings. Alex Bottai of Inline Fib e r g l a s s of Ontario, C a n a d a , says t h a t FRP is t h e only high insulation, high s t r e n g t h m a terial suitable for tower b l o c k a p p l i c a t i o n s .

Inline m a k e s six styles of pultruded FRP window frames and two types of p a t i o doors.
