Winterizing a balcony or loggia

Winterizing a balcony or loggia is for different reasons. Who wants to
add living space to the apartment , making the loggia of extra room
and some - just to warm shelter. In many older homes, especially in the Khrushchev ,
in winter , cool enough , precisely because much of the heat "goes "
through the balcony and " warms " the street.

The heat of the apartment and the balcony is influenced by many factors: the material from which
built the house where the windows open, even wind direction and strength, "make the weather"
in the house. Sometimes warming balcony - the only chance to save the apartment from
the cold and get rid of ice dams on the balcony door. Carry out work
on warming the balcony at any time of year, but experts recommend
do this in dry weather at positive temperatures. Warming of the balcony
or loggia - is not only a first step in glass to preserve the heat in the apartment
- It is certainly setting windows and glazed balcony. It can
be based on aluminum extrusions and PVC profiles. Recently
popular natural wooden windows. Wooden frames are impregnated
antiseptic and painted in several layers, which significantly increases
their resistance to weathering. However, mistakenly believing that by
Glazing any problems with the heat losses will be solved. Installation of glass -
are not the only warmth, but only one of its stages.
Just note that output to central heating balcony prohibited construction
standards. Therefore, to the loggia was warm, will either expose
there the electric heater or any other heater, or lay
floor heating, which is not always advantageous, especially when you consider that
electricity prices are increasing every year. Therefore, in order to balcony
or balcony became warm, and energy was spent on heating their minimum necessary
not only to glaze them, but also to insulate. That means to insulate the floor,
roof, front balcony and its sides. Wall between the apartment and balcony
insulated in the event that the glass balcony is not going as well in an apartment
very cold. What material will retain heat? Typically, materials for
insulation balconies or loggias are mineral wool from different manufacturers
polyethylene foam, extruded polystyrene, as well as a "sandwich" panels
prefabrication. The cheapest way for warming or balcony
loggia - a thermal insulation materials based on polystyrene and its derivatives.
Their main advantages, apart from relatively low cost - low weight and small
thickness. Disadvantages include brittleness and low durability. More
"Solid" insulation by means of mineral wool. Thickness
layer of this insulation varies from 50 to 150 mm - a specific value
selected depending on the climatic conditions in the tables that
contained in SNiP 23-02-2003, SNiP 23-01-99 and SP 23-101-2004. Sometimes balconies
and loggias insulated "sandwich" panels, but this method is not particularly popular
because of significant weight and thickness of the material (as compared to the others,
as well as a kind of industrial design. We can formulate the main
requirements for the heater to the balcony: the material must have low weight (it is
necessary in order to avoid creating unnecessary burdens on the ceiling) and
have low teploporovodnostyu, which determines the required thickness
layer. This is a very important parameter, since it ultimately affects the size of the
balcony or loggia. Two other important properties of the material - it is moisture
and breathability. How to deal with the "dew point" specialists recognized
that the best way insulation is insulation "outside", with
Cold side wall surface. According to SP 23-101-2004 "Design
Thermal protection of buildings ", SNIP 23-02-2003" Thermal protection of buildings "and SNIP
01/23/99 "Building Climatology", "when designing thermal protection for residential
building location, preferably outside the insulation, that is not recommended
use insulation on the inside because of possible accumulation of
moisture (condensation) in the insulating layer. However, if necessary
such an application surface of the premises must have a solid
and durable vapor barrier layer. However, with balcony or loggia
in an apartment building that option is not always - they basically
insulated from the inside. And in winter the apartment owners are faced with a problem: Unknown
how to lodge there insulated condensate. Especially his many, if
in the room where the balcony door leaves, high humidity, such as
in the kitchen. With insulation balcony or loggia inside moist air coming
of the structure passes through a heat layer and reaching the cold exterior
Wall balcony, turns to water, which subsequently flows and forms
those "who had taken the puddle of nowhere." The fact that domestic
insulation "dew point" is located in, under the same external - on the outside
home, which leads to the preference of the latter method. "Dew point" specialists
called the temperature to which air must be cooled to keep
it reached the state of water vapor saturation and began to condense into
water. Away from the balcony, the condensate! The first condition of "dry" balcony or loggia
- This is true selected heater. The material must have vapor barrier
layer of foil or polyethylene. He has many insulating materials
based on polypropylene and some glass and mineral wool insulation.
For example, the insulation ISOVER KT 40-AL-plated aluminum foil,
which is both heat-and material parobarerom
(So ​​they even warmed the sauna). Install insulation to completely parobarerom
meets building codes. Winterizing a balcony or loggia
reduces heat loss in the apartment by 30%. This means that such
precious cold winter warmth is no longer warm outside.
