Inspection of Material
|
| |
ⅰ
Before material is delivered to
the site, a test report issued by
a state authorized institution should
be
submitted
to the site manager or the supervisor.
ⅱ In case
of material that has been already
delivered to the site, if necessary,
the site manager or the
supervisor should request a state
authorized institution to issue
a test report for quality management. |

|
Transportation, Storage
and Handling of Material |
| |
ⅰ
When transporting, storing and
handling the material, care should
be taken not to damage the sound
absorption
material.
ⅱ The material
should be stored, separated in
accordance with its characteristics,
uses, types and shapes,
and should
be kept away from sunlight or
humidity.

General Instruction
for Construction Work |
| |
ⅰ
Auxiliary thermal insulation material,
installation material and tools
should be prepared depending on
the
thermal insulation
material and work methods.
ⅱ The surface to
attach thermal insulation material
on should be cleared of nails, metal
wire and mortar, cleaned
and smoothed,
in order not to cause any problems
in the construction work.
ⅲ In case multiple
layers are installed and it is necessary
to join T-MAX, the joining areas
of each layer should
not overlap those
of the other layers.
ⅳ Any gaps between
the materials should be avoided
as much as possible. If there are
gaps, they should be
filled with snippets
of T-MAX products. |

Work Methods for
Walls |
| |
ⅰ
Free Cap Method
Clean the base
surface → Determine the locations
of free cap pins and fix the pins
(at 314 x 450 mm intervals)
→ Install T-MAX
→ Set Caps → Finish with G/S
ⅱ Furring Strip
(Styrofoam) Method
Clean the base
surface → Ink the lines (at 330
intervals) → Install Furring Strip
(Girth) → Install T-MAX
(330 x 1,800)
→ Finish with G/S
ⅲ Dry Wall Method
Clean the base
surface → Fix runners/studs →
Install G/S 2 plies on one side
→ Install T-MAX → Finish
G/S 2 plies
on the finishing side
ⅳ Double Bracket
Method
Clean the base
surface → Ink the lines (at 450
x 330 intervals) → Fix double
bracket pins → Install T-MAX
→ Set double
bracket caps → Finish G/S
ⅴ Pin Method
(for Ceiling)
Clean the base
surface → Determine the locations
of pins and fix them → Install
T-MAX → Set pin caps
→ Finish G/S

Warnings for Construction
Work |
| |
ⅰ
Properly ventilate the thermal insulation
material that has been filled, so
that it can dry properly
(in case of masonry
Block Structure).
ⅱ Inspect and make
sure that the thermal insulation
material has been evenly filled
without leaving any gaps.
3) Make sure
that the thermal insulation material
has been tightly secured to the
wall surface
ⅲ In order not
to allow expansion of the material,
install the wooden surface frame
so that it matches the
thickness of
the thermal insulation material
on the wall surface. Cut the material
around the frame and make
sure that the
material fits with the frame tightly
then install the Furring Strip (Girth).
ⅳ Pay attention
so that there are no gaps in the
thermal insulation material at the
joint areas in the walls and
floors.
ⅴ Construction
work of thermal insulation in the
ceiling should be done when attaching
the finishing material.
The thermal insulation
material should be cut to precisely
fit with the frame.
ⅵ After installation
of the ceiling base material or
the ceiling finishing material,
install the thermal insulation
material tightly
so that there are no gaps between
the sheets or at the joint areas
of the ceiling and walls.
ⅶ Safe handling
of the material ensures smooth work
completion but always pay attention
to avoid any accidents
during construction
work. |
