Hi,
I've got spreader plates currently being installed, and at first they were installed incorrectly. The insulation was installed too low and so the plates bent from the joist down to the boards rather than being flat. They were also installed overlapping.
This is now being rectified, however I'm a little concerned about the uniformity of the plates. If they were installed properly initially then the plates would be completely flat, however as they have been bent previously I'm concerned there might not be full contact between the plate and subfloor and so be less efficient.
I've attached photos of the plates. It still needs to be redone (boards need to be brought up a little) but are the plates ok to use if installed correctly or should I just scrap them and get replacements to ensure uniformity?
Thanks!
