I need some curved upvc gutters and a friend has told me that with the very
careful application of heat some brands of plastic gutters can be curved but
apparently other brands will just either just burn or crack. He doesn't
remember what make burns and what bends, has anyone any experience of
reforming gutters using heat?
I don't know whether it's possible, I have only heard of this being done
with plastic waste pipe. If this is for running straight lengths past
none-90 degree angles then a possible alternative is an adjustable gutter
angle: http://tinyurl.com/yxlvpa . If you are able to heat bend upvc gutter
you need to consider whether the gutter brackets will fit the new shape.
Practically impossible to do as you will have to stretch the outside of
the curve only.
Best way is to 'cut & shut' the section/s of gutter to suit the curve
you want and them get it PVC hot air welded together. The manufacturer
may be able to give a fabrication service but a lot of PVC Window
Manufacturers have hot air guns. The welding rod colour maybe a problem
here as most windows are either white or brown. If you choose grey
gutter you may have a problem.
I have 'heat manipulated' a lot of PVC and ABS Soil & Waste in my time
but would not dare attempt what you propose.
