Just adding a new rad in a new location downstairs (suspended timber floors) and wondering whether to use plastic or copper pipe and how to insulate.
- Is it necessary/desirable to add insulation to plastic pipework or is it only necessary for copper?
- Wickes have two different types of pipe lagging - one which is by-law compliant and another called "economy" insulation at a quarter of the price. Is the economy one an inefficient, token gesture at insulation or is the by-law compliant one an overpriced, unnecessary expense?
- Hardly dare ask this but does anyone know any pros and cons re: copper vs plastic? Current plumbing is copper, but I have a hacksaw so cutting plastic pipe holds no fear for me;-)
- Finally, is it good practice to lag first floor pipework or is it unnecessary?
Thanks for any advice.
