Carpet rods and underlay

freezspirit

Sorry if this has been asked several times before but I have a few queries that need answers. At the moment I'm doing up a 2 bedroom bungalow almost finished running the barrier pipes to and from radiators to boiler room after which I will be doing the flooring.

The floor is 12mm plywood. The original underlay has been either what appears to be the basic red or green Tredaire in a very poor state. The gripper rods too are a mismatch of brands with rustly nails and hooks. So have decided to replace every thing with new.

I do remember a thread way back around Christmas time on gripper rods but can't find it. It was on which company to stay away from and which gripper rods were good/great quality and where to get them from.

Same with the underlay I would like to know what to get and where from. I want something that will last and will give good sound/ heat insulation.

I would like to tape the underlay as having spent a coulpe of days on my all fours removing staples from the floor I think it would be quick and safer on the pipes. Again some staple were rusty and alot didn't even hold the underlay.

Also do you use underlay in the kitchen and bathroom? I only ask as kitchen and bathroom have original flooring cover that is glued to the plywood (done 30 years ago) but seems I've had to cut the flooring to lay pipes its not a universal waterproof layer. These rooms will have either vinyl or laminate flooring.

overall underlay will be approx 57m2
gripper rods approx 85m

Any idea on cost?

12MM Plywood floor is not suitable for flooring, 18mm is the normal thickness.

Yep I thought that too, even the surveyer said 18mm but once we bought the bungalow and started work on it the plywood is in fact 12mm. A couple of the boards says Canadian exterior plywood.
