Suspended Ground Flooring Condensation Downside

Furthermore, the gaps between the last joists and the walls were uneven so that a few adjustments to the boards had been wanted to get the insulation to suit as snugly as possible. It is necessary, that no air can flow into across the insulation board; otherwise, it will dramatically scale back the insulating effect. Floors are constructed in two ways, either suspended or solid. Suspended timber floors consist of floorboards nailed to joists, typically carried on ‘sleeper’ walls of brick. It is important that the underside of a suspended flooring is ventilated to avoid the build up of moisture. We used 200x50mm C16 joists and we ensured that there was at least a 150mm hole between the bottom of the joists and the ground.

Can You Put Insulation Over Existing Insulation?

• It is essential, that no air can flow into around the insulation board; in any other case, it might dramatically cut back the insulating effect.
• This made it onerous and fiddly to get the board into the proper position.
• As the joists were typically at an angle, the underside opening between them was smaller than the gap on the top, slightly below the floorboard.
• The best insulation material for crawl areas is inflexible foam insulation board.

This raises questions about the validity of utilizing such models in housing inventory fashions to tell retrofit decision-making and area-heating-reduction interventions. In an uninsulated floor, the ground joists add extra thermal resistance, but as soon as the floor is insulated , the joists turn into a thermal bridge compared to the now higher insulated floorboards. Ideally insulation is also put in underneath the joists, especially within the perimeter area where there are sleeper walls. This can be carried out as an additional layer of insulation after insulating in between joists. If you could have an unvented crawlspace or basement, you have to insulate the walls instead of the ground joists.
