Best Pipe Lagging to avoid sub- zero stop-tap water Freezing

[Jeff543]

My stop- gap pipe is not near any of our radiators, that area gets very cold. I'm concerned that the water will freeze. Any tips on best lagging?

Do you mean stop-tap?

The incoming water supply?

Is it inside the house?

yes but no radiator there. Its by the front door.

I've only had a boiler since last winter. |Before that the pipes would freeze every winter when we had a couple of days of sub zero temperatures

If you aren't on a water meter, leaving a basin/sink/garden tap, very slightly open, may be enough to prevent the pipe from freezing.

I am not a plumber though...

A picture would help enormously. If it is in a cupboard or similarly non heated space then just wrap it in loads of loft insulation.

If it is inside a heated house it is most unlikely to freeze.

You can use stiff plastic foam pipe lagging, which is like slitted tube. The thicker the better. Foam has twice the insulating power as the same thickness of mineral wool. Felt is not much good.

If it is against a cold external wall, insulate it from the cold wall rather than the warm room.
