I'm looking to tile the patio and have found a good deal for porcelain outdoor tiles that are R9 slip rating.
I have no idea how that translates to real world, there is minimal slope but it will be rained on.
I can also find tiles with R12 rating but close to 2x the price, again I haven't a clue how much difference that would make.
Obviously if I can get away with the cheaper tiles, then great but not if it means much higher chances of busting an arm or leg.

The reason why I am looking at porcelain tiles is they are thinner than slabs, 10-20mm vs 38-50mm. I don't want to raise height of the patio so
as not too risk breaching damp course and thicker slabs will create a step from the garage to patio.
Thinnest slabs I've found are 38mm.
My mother has some porcelain tiles in the front porch, and when the get wet they are lethal,
I wouldn't have them just for that reason

Leave the tiles short of the wall and backfill with gravel so any water drains away.
Internally I wouldn't use anything less than an R13 in a bathroom or are that will get wet, so I'd say the same for outside.
I've got Travertine flooring downstairs and if you stand on it with a wet shoe its like an ice rink.
