The greatest answer is “possibly.” If plates aren't used then you are relying on air and the few areas where tubing is in touch with the ground to transfer the heat. The problem is, air is an insulator and Pex immediately in touch with wooden is a poor conductor. In order to make up for this poor heat transfer, the water temperature should be raised considerably.

If you’re referring to putting plastic sheeting over the underside of the ground joists within the crawlspace, you shouldn’t as it's going to act as a vapor barrier and trap moisture from the house within the ground joists.

Water and radiator pipes within the void must also be insulated, with no gaps within the insulation sleeves as this will become a floor for condensation, contributing to moisture points in the void.

• For homes without basements and people with unheated cellars, adding insulation can bring heating costs down.
• This raises questions concerning the validity of using such models in housing inventory fashions to inform retrofit choice-making and house-heating-discount interventions.
• There are roughly 6.6 million dwellings in the UK constructed earlier than 1919, predominantly constructed with suspended timber ground floors whose thermal performance has not been extensively investigated.

Woodfibre insulation could be suitable, but messy; mineral wool insulations are suitable however not at all times vapour-open, considered an additional advantage in flooring as a result of potential /seasonal moisture construct up. Sheeps wool is suitable, but moth infestations have been reported in some cases, notably where ‘chickenwire’ was used to droop the insulation on the underside of joists.
