Coldseal windows what profile?

[Steve2009]

Can anyone have a stab at what profile my 2001 coldseal windows would probably be?

numbers on the frame read:

Line 18 HW Plastics
UL 1502 BS7413 1991 23/03/01

I am searching for compatible run up blocks/wedges

cheers
Steve

HW = Heywood Williams, you could try contacting them but I'd imagine you'd be very very lucky if you got anywhere, I used to bash them off and chuck em when I fitted for coldseal, horrible things for a horrible profile, worst windows I've ever fitted and the most horrible time in my fitting career

From memory they were like these

similar to those yes. not quite the same. Glazpart had one on their lists exactly right but they hadnt made it since 2009 when I emailed them. It looks like Heywood Williams went tits up around the same time as Coldseal. funny that...

know of any similar profiles at all?

Can you not just Toe and heel the sash? Run up blocks are for the bin
