The noise effect of the room
door should reach 25 to 22 db. From the use of materials on the
bedroom door, solid wood doors and solid wood composite door
noise performance than the free paint doors, steel doors, molded
doors, etc.. Different from the door, T door (at the door) than
the traditional flat door closed sound insulation effect is
good.
For solid wood door and solid wood composite door, the sound
insulation depends mainly on the door of the filler. Usually,
the doors of filling in the paper base honeycomb structure,
sound insulation effect, is the best in the core board door,
sound insulation effect can reach 32 db. In addition, high wood
density, weight, thickness of the wooden door, there is a very
good sound insulation performance.
Sound insulation plastic steel door depends on the thickness of
the glass and the type, the best cut glass doors, double hollow
glass door sound insulation effect, suitable for the bedroom,
parts of partition between the kitchen and living room or study.
Even the good quality of sound insulation door, also need a
seamless installation, installation will not affect the sound
insulation effect. So please professional installation of door
and door.
What noise effect is good?
1 full solid wood door
olid wood door is made of natural log door core, through the
boring processing, processing and into. High grade solid wood
doors are more valuable timber. Price for
The wood materials, texture and so on different and different,
high-grade wood has wood of walnut, cherry, Shabili, rosewood,
pure solid wood doors, higher requirements on the manufacturing
process requirements, dehydration degreasing solution well, or
easy to deformation and cracking, so choose the strength of the
manufacturers of products. The situation there is a wooden door,
although the data is also full of wood, but wood frame, wood
core plate, fiber glass door core, top surface veneer wood
doors, adhere to the style, the price is relatively low, but
once the moisture, easy degumming, cracking, mildew.
2, solid wood composite door
Composite material of many kinds of doors, it is in solid wood
to do within the support or frame, with high density of fiber
panel may be in the board, particle board, etc.
Industry composition data, the final appearance and then paste
with wood and color paper or film made of PVC. Composite doors
of various shapes, rich style, the price is relatively cheap,
compared to the pursuit of fashionable young people like.
However, some of the products because of the use of glue and
wood disposal but off, not water, easy to pollution.
3 molding door
Molded wooden doors as a composite door, because the price is
more economical and practical, and safe and convenient, and then
by the popular family of love.
Molded doors is high density fiber board molded door skin
consists of two pieces of wood with modeling and simulation by
mechanical pressing into. With moisture, expansion coefficient,
anti deformation characteristics, after a period of use, the
appearance does not appear cracks and discoloration phenomenon.
General composite wood doors in the delivery of a neutral white
primer, consumers can go home after the white neutral primer
based on personal preferences and then color, meet the needs of
consumer characteristics. Compared to the hand made solid wood
door, the door is made of mechanical production, so the cost is
low. Because the door is hollow, natural noise results relative
to solid wood door is also worse. Molded door there is a problem
worthy of attention, it is that the release of harmful gases to
form an indoor pollution.
How to detect the effect of sound insulation door is good?
1, look at the weight. Sound insulation formula and the density
of the material has a direct relationship, so the density of the
sound insulation is relatively good, the door is relatively
light, this is the source of the noise is not good. But the
attention: the middle of the flat plate hollow door and the
sound insulation cotton will be even more noise than the solid
wood door.
2, look at the thickness of wood facade laminates. The thicker
the surface layer, the better the effect of noise insulation.
General wooden doors of the use of the surface layer should be
8mm thick. The thickness of the surface layer is also better,
but the cost will be higher. But the tin surface layer: 3mm
thick iron fire door, sound insulation effect is good.
3, look at the level of the wooden doors. The flat wooden doors,
Mentao combination with better, but no matter what the
structure. As long as the deformation of the insulation doors
must not, air leakage.
4, there is a little professional, expansion glue quality
between the wall and door, this point is not good it will
seriously affect the sound insulation.
Note: in fact, the doors and windows industry noise with the
fire door is a class, rather than a single definition of a
certain content. The concept of "sound" and "sound". The
principle is sound depends on the quality or material density
(time, when the iron door unit area total weight less than its
sound than wooden doors), and sound absorption depends on the
surface area of the material and fine surface roughness (space
rock wool, mineral wool, and the foam is not insulation
sound-absorbing material).
