Upvc window fixing

[dodo2]

What is normal practice with regard to fixing Upvc windows along the bottom? Should fixing bolts be used along the bottom or are bolts at proper spacing in the jambs sufficient? Concern is that bottom fixing will allow water seepage into the channel containing reinforcing, and down into brickwork.

Best way of fixing UPVC is a skip.

Thanks Oilman....I'll just skip that tip for now if you don't mind.

Not seen a skip with a window fitted

dodo2,

What are the length of the window?

 

[dodo2]

Hi masona,

Lengths are 180cm and 120cm

Thanks

Just use fixing on jamb side and bedded the sill with sand/cement although you can fix one in the middle of the sill if you want to but not easy if it's a cavity wall but normally a window board will strengthen it when glueing into the windowboard slot.

masona's reply has prompted another question...what's the view on mastic or expanding foam as a substitute for a mortar bed?
