ProofTherm by ProofShield

Hi all,

Has anyone had any experience using the above product? If so, what do you think?

I know the traditionalist in me stays that i should go with a true Lime based external render. However I quite like the sounds of some form of insulative properties being put into the render and the fact that it can cure (subject to environmental factors) in around 8 hours.

I have been checking the vapour permeability of the product compared to NHL based renders and it seems pretty good on paper. Below is a quick comparison between each type of Lime Render for comparison:

ProofTherm 6.27 (reported)
Lime putty render 4 – 6
NHL 2 lime render 5 - 8
NHL 3.5 lime render 8-12
NHL 5 lime render 12 - 20

I have a solid brick building so keen on doing the correct approach but not afraid to using different products that potentially can create the same results.

Anyway - a bit of an open discussion really. Any thoughts?

Cheers!

It’s basically just a pre-mixed hydraulic lime and cement mortar with perlite added and presumable some pozzolans to make it “go off” a bit quicker

ProofTherm is a breathable, insulating, mineral render whose primary components are cement, hydraulic lime, insulating aggregates, proprietary binders, and polymers. It is available in different formulas as an external wall render, internal wall plaster, and self-levelling floor screed.

Personally I’d give it a miss, you could mix up your own for less money with greater breathability
