CONCRETE
/ SCREED SYSTEM
These are the most
commonly used system. Insulation is placed on top of a ground bearing
concrete slab, 'block & beam' or suspended concrete floor with a damp
proof membrane if required. Clip-rail is then fastened to the insulation
with PEX pipe fixed into place. The clip rail also raises the pipe away
from the insulation allowing the sand / cement screed (min 65mm) to flow
all the way around the PEX pipe, ensuring full conductivity. Edge
insulation is laid to prevent a thermal bridge between the screed and the
exterior wall.
The screed must
comply with British Standards codes of practice.

FLOATING
FLOOR SUSPENDED
The FLOATING FLOOR system can be
used as a substitute to screed over a slab for a wooden floor.
Pex pipe lays
neatly in aluminium heat diffusion plates which are placed into specially
routed 50mm polyurethane insulation.
The plates then spread the heat
resulting in an even surface temperature and the thick insulation prevents
the downward passage of heat.

TIMBER
SUSPENDED JOISTED FLOOR
The PLATE SYSTEM can be used to
spread heat evenly under wooden suspended floors or as the PUG system where
a mechanical fixing is required.
Wooden floors fixed to joists
require a minimum of 25mm polyurethane insulation to be fixed between the
joists or battens to prevent the downward passage of heat. If your joists are
not at even 300 or 400mm centres we advise cross
battening at these spacings.
Aluminium plates are then fixed to
the joists/battens with 17mm pex pipe neatly
fastened within to aid in the conductivity of heat.

TIMBER
SUSPENDED CROSS BATTEN FLOOR
The PLATE SYSTEM is also used to
spread heat evenly under wooden floor where cross battens are used.
This system requires a minimum of
25mm polyurethane insulation to be fixed between the joists to prevent the
downward passage of heat. Cross battens are fixed at 400mm centres
and aluminium plates are then fixed to these battens with 17mm Pex pipe neatly fastened within. The aluminium conducts
the heat and spreads it throughout the surrounding area. Battening requires
no notching or drilling of joists.

PUG
FLOOR SYSTEM
The PUG system can be used with
either solid or suspended concrete floors, where a mechanical fixing is required
for a timber floor finish. The system requires a minimum base of 25mm
polyurethane insulation. Plastic Clip-Rail is fastened to this base
and 17mm Pex pipe fixed into it.
A concrete screed covers these
materials and should sit level with the batten, a minimum of 30mm. As the
screed is directly beneath the covering board, conductivity is increased.
Insulation must comply to building
regulation
