Delta Ž FL
DELTAŽ-FL - The perfect plastic subfloor system for concrete and slab on grade
floors.
This air-gap membrane is made up of a special high-density polyethylene resin
(FDA approved), providing a dimpled surface with outstanding compressive
strength, impact resistance and long-term performance.
DELTAŽ-FL is a uniquely dimpled, heavy-duty grey plastic membrane that keeps you
and your family warm and comfortable in your basement, or any room in the house
with a concrete, slab-on-grade floor. The membrane is installed with its dimples
down to create a 5/16-inch thick air space above the slab, and can be covered
with a plywood subfloor and topped off with carpet or flooring systems.
DELTAŽ-FL on concrete floors protects sensitive materials by exploiting the
concept of vapor pressure - that is, water vapor seeks to equalize its pressure
by moving from areas of high pressure to areas of low pressure.
In a conventional basement, dry air in the living space acts as a magnet for
water vapor seeping up through the concrete. But with the DELTAŽ-FL system, the
space between the dimples provides a sufficient air-gap to equalize the water
pressure above and below the concrete slab.
Though the air in the living space is completely isolated from the system,
DELTAŽ-FL is designed to allow small amounts of water vapor into the room to
maintain a healthy humidity level.
The membrane also provides a thermal break that generates instant comfort and
warmth for your basement. DELTAŽ-FL is an inert material. The air-gap membrane
has an outstanding compressive strength of > 250 kN/m˛, is extremely tough and
rugged and can withstand heavy loads which allows for any finishing on top of
the membrane.
The reduction in head room is minimal and the product is extremely easy and fast
to install. DELTAŽ-FL comes with a 20 year product warranty.
