slab insulation

slab insulation

Thermal insulation which is fabricated in rigid or semirigid form; differs from block or board-type insulation only in physical dimensions. The slab designation usually is applied if the face dimension is much larger than a block but smaller than a board and if the thickness is greater than that of a board.

The solvent contaminated the soil and ground water around the building and is believed to have been trapped in part of the building's floor slab insulation, which was necessary for refrigeration when it was an ice cream factory.
However, there are still many areas left for improvement: oversized cooling and heating systems; lack of slab insulation; poorly sealed bottom and top plates; inadequate ventilation in tight homes; unsealed interior furnace closet doors; and un-vented gas fireplaces in tight homes.
* Slab insulation. A flexible insulating material beneath the concrete slab prevents energy loss to the ground.
A Although rolls of fibre insulation are cheap and great for loft floors, it's worth buying the rigid slab insulation for walls and ceilings.

Use lightly tightened nylon or plastic-coated metal wire ties to wire mesh or barbed staples into slab insulation. Uncoated wire ties can damage the polythene tubing and un-barbed staples can pull out of the insulation during the topping slab pour, allowing the tubing to drift from its initial location.
This "seat" will receive the perimeter edge insulation, and the perimeter slab insulation as well as the concrete.
For the room/return plenum, the model performs a steady-state heat balance on each of the three major architectural layers of the heat transfer system: (1) the top surface of raised floor (carpet), (2) the bottom surface of slab (or slab insulation, if present), and (3) the suspended ceiling (if present, assumed to be a uniform temperature [infinite conductivity]).
