    GRP was popular for a while for things like dormer windows but as it degrades and moves like billy-o it is not very durable. The decorative 'plasterwork' on Kenwood House in London by Robert Adam is GRP. On a sunny day you can actually hear it all expanding. It is not especially popular as a roofing material (eg Topseal) and there are more cost efficient alternatives.

    Different lands, different customs. It's not inherently "better", you know. You might as well ask "why do Europeans favour front doors that look like shower doors instead of solid ones like they use in thee rest of the world?"
