Upofloor Tuplex is a new-generation underlay
for hardwood flooring. Tuplex is made out of two layers of solid
polyethene with flexible polystyrene granules between the layers.
This structure makes Upofloor
Tuplex a clean, durable and lightweight material that is easy
to handle and install, even in confined spaces. Tuplex also
provides a highly effective double moisture barrier against
subfloor humidity, obviating in most cases, the need for a separate
moisture barrier.
Specifications
Levels out subfloor
- Flexible construction helps smooth out any minor
irregularities of the subfloor, and provides an ideal base
for hardwood flooring.
Ventilation -
Tuplex’s granular composition creates space between the
floorboards and the subfloor, allowing for efficient ventilation.
Moisture barrier -
The two-ply polyethene film of Upofloor Tuplex makes it a highly
effective double moisture barrier. In most cases, there is no
need for a separate moisture barrier. A test report is available
form the manufacturer.
Sound insulation
- Tuplex underlay, combined with any commonly used
intermediate floor construction, meets the requirements pertaining
to impact sound insulation in intermediate floors. Because of
its high flexibility and resilience, its sound insulation properties
will never wear out. A test report is available from the manufacturer.
Easy Installation
- Laying the hardwood flooring is one of the final
phases of interior decoration. At this point the room is usually
full of recently finished surfaces, which must be protected
against dirt and dents. Upofloor Tuplex is a clean, durable
lightweight material that is easy to handle and install, even
in confined spaces.
Installation
Before installation, make
sure that the subfloor is clean, dry and level. The relative
humidity of concrete floors must be under 85 %. Check that
the floor surface is level with e.g. a ruler or a straight
floorboard: - max 3 mm deviation allowed over a length of
2000 mm. Where necessary, level out the subfloor, using a
good quality levelling compound.
Prior to installation, remove
any dirt and dust form the subfloor. Roll out a strip of the
underlay on top of the subfloor, leaving a narrow gap (appr.
5 mm) between the underlay and the wall.
Roll out more of the underlay,
joining successive strips with butt-seams and sealing off with
plastic tape, 5 cm minimum width.
