Subsequent Insulation of basement ceilings

Above or below?

The thermal insulation of the basement ceiling is often too little attention. But even here there is a way to save energy with little financial outlay.

The simplest type of retrospective Thermal insulation of flat solid floors is sticking or plugging of insulation from the ceiling side. Faucet (for example, water, heating, electricity) require the retrofitting of insulation layers of special attention. Ceiling lights may need to re-fastened and their connections are extended. The maximum insulation thickness may be limited by eg directly beneath the basement ceiling, built-in cellar windows.

basement ceiling with odd and uneven bottom (caps or vaulted ceilings) are only using a sub-support structure or later dämmbar.
are most meaningful substructures, transverse to the support systems run, since the distances of these carriers usually over 1.00 meters. Otherwise you will need a stud again be appropriate to the distance of the used lining (plasterboard, plasterboard, etc.) is adjusted. All joints and connections of the edge support structure must be designed so that an uncontrolled flow behind the insulation material is prevented with room air.

as material for the floor structures are suitable flexible insulating best. It is also possible to install only the sub-structure with cladding and to subsequently blow the cavity with insulation.

The insulation on the floor It only makes sense if a hobby of living space and adequate room space is available. The necessary building heights be at least 6 - 10 cm. The follow-up (eg, cut doors, radiator, set it higher) and were the entrance to the apartment resulting paragraphs and thresholds to be considered.

Do you have a cold or a hot cellar?

The basement ceiling is always under construction so designed as a floor. Nowadays, most often used in new buildings a blanket of reinforced concrete. To improve the sound insulation properties are on the reinforced concrete floor impact sound insulation placed. In general, it is the relocation of a wet stroke.

ceilings contribute significantly to the reinforcement of buildings because the walls are standing in different axes positively connected to each other and brace each other. To reduce sound transmission, a possibly existing ceiling space is completely filled with mineral wool insulation.

In basement ceilings are two possible scenarios:

• Heated basement
• Unheated basement

If the basement is not heated, so is the basement part of the heat-transferring enveloping surface and must be insulated in accordance with the requirements be possible to keep the heat losses to the outside. The insulation can be the top side, and in addition to sound insulation or other, in the basement, attached.

is heated the basement should be taken in the usual insulation of the floor and walls.

limits must be observed

If you want to clean up an outside wall or re-build, you must observe certain values of the EnergieEinsparverodnung (EnEV) or comply. These are usually around the U-value (= heat transfer coefficient) of the relevant wall. The distinction between buildings with EnEV a normal (> 19 °) and buildings with a low internal temperature (< 19°).

• Normal indoor temperatures require U-values between 0.45 W / (m² K) and 0.35 W / (m² K).
  
• Lower internal temperatures allow U-value of 0.75 W / (m² K).

to achieve the required U-values for buildings with normal internal temperatures are in the renovation, depending on the existing wall structure and the desired insulation material, usually insulation thicknesses of 8-12 cm is required .

These heat transfer coefficients do not have to be met if:

• Evidence for the entire building is performed.
• The change in less than 20% of the wall surface to the same side of the building concerned.
• The expansion is at least contiguous 30 cubic meters.

Where and how can be insulated?

pitched roofs have changed considerably in its structure in recent decades. The task of the best tile roof was to protect the building from damage by the elements. The ample sized and often unused roof space was due to the high number of joints of roofing ventilated very well, and so provides a Humidity and temperature compensation.

housing shortage and rising construction costs, however, led to increased use of housing reserve. Thus, the period for the simple roof, a high-quality component building physics with a variety needs. The high demands on the heat, noise, fire and moisture protection are met by a layer structure that uses the property for optimum performance and building materials.

The insulation technology running pitched roofs, a distinction on the location of the insulation between rafters

• About
• insulation between rafters
• Under rafters

result of tightened requirements for thermal protection (through the Energy Conservation Act EnEV) are now often used combinations of intermediate and under rafter insulation. The layer in which the sub-rafter insulation is located, is often used as an installation level.

The version with the roof insulation boards (see adjacent figure) and thus allows a continuous transfer of thermal bridging of the insulation on the rafters. The rafters can be run as a visible rafters. An additional rafter insulation is also possible.

Basic requirements

EIFS in all its layered structure as a system of one manufacturer in accordance with the manufacturer's guidelines to perform. In addition, the provisions of the relevant building regulations concerning the fire performance of the materials used, particularly the insulation materials are observed. Depending on the province and building height may be permitted or demanded:

• Flammable materials (B2)
  
• combustible materials with a strip of non-flammable insulation above window and door openings
  
• flame-resistant (B1)
  
• non-combustible materials ( A1 or A2)

Finally, the stability the exterior insulation system must be guaranteed. Depending on the height of the building, carrying capacity of the soil and weight of the composite thermal insulation system can be allowed or demanded:

• bonding of insulation to the substrate without mechanical fastening
  
• bonding the insulation with additional doweling
  
• laying the insulation in a pegged aluminum rail system
  
• dowel construction approval
  
• Simplified stability proof
  
• stability proof

other basic material and construction

Curtain, ventilated facades (VHF) consist of the components:

• clothing
  
• ventilation
  
• insulation
  
• substructure

clothing
In a VHF a wide range is of possible facade cladding as a final weather protection and freedom of design of the facade are available. Depending on the design desired, a "light" cladding or a "serious" clothing will be selected. As clothing materials are commonly used:

• aluminum composite panels
  
• Fiber cement
  
• fiber reinforced Harzkompositplatten
  
• wood
  
• wood cement
  
• high-pressure laminates (HPL)
  
• ceramic
  
• natural stones
  
• titanium zinc
  
• support plate systems for plaster, ceramic and glass applications
  
• brick

The VHF is not a composite system, but the components are insulation and weather protection structurally separated from one another. The intermediate ventilation space regulates the financial climate. Use or building moisture is removed by this upwards, moist exterior walls be dry in no time. The two-tier system separates the functions of the VHF weather protection and insulation .
be used mainly for VHF mineral insulating materials for thermal, acoustic and fire protection, offer themselves for any use and building height. Insulation can be placed in any required thickness.

The substructure is the static link between the supporting outer wall and the actual cladding. As materials are steel, wood or aluminum or a combination are available. The majority has prevailed aluminum. These substructures are three-dimensional adjustable and lie down without force to the building structure. Unevenness and Wandversprünge can ausgleichen.quelle easy gieselmann.info
