Basement ceiling insulation and insulate

Instructions for basement ceiling insulation

Basement ceiling insulation and insulate

A basement ceiling insulation unfortunately still keep many homeowners unnecessary. Here lies particularly in older buildings right there a lot of energy-saving potential.

If you want to insulate the basement ceiling and isolate the costs will pay for itself quickly, as can be expected with an energy savings of 5 to 10 percent.

In order to infiltrate any error in the insulation of the basement ceiling, we explain in our guide on how the basement ceiling insulation is done properly. We differentiate between the following variants:

  1. glue insulation panels directly to the ceiling
  2. rafter insulation

Low energy consumption with proper basement ceiling insulation

The basement ceiling insulation is only part of the insulation from the inside. To ensure effective energy saving, complete isolation of the house should be made.

Despite its important function, a basement ceiling insulation is missing an estimated 90% of all German households. This is reflected especially in homes that were built prior to 1995. Because only in that year, the EnEV law came (the so-called Heat Act) came into force, in which the outside perimeter insulation of the floor slab and the basement was prescribed. Because lost by the lack of insulation between the heated rooms on the ground floor and the basement constantly goes over heat the soil.

The thickness of the insulation depends on the height of the ceiling. The thicker the insulation is, the lower depends ultimately the ceiling. Nevertheless, they should at least 6 cm thick be to achieve an effective energy cost savings. Ideally, its thickness is up to 12 cm.

Preparation for insulating the basement ceiling

Basement ceiling insulation and insulateThe insulation must be cut before further processing.

For rafter insulation is rock wool. It is flame retardant, so it does not burn brightly immediately in case of fire. Instead, this insulation glows only smokeless. This gives the homeowner or the fire department enough time to extinguish the fire before it can spread to other rooms. At the same time rock wool is used as soundproofing.

Polystyrene plates can be easily stick directly to the ceiling. The direct bonding has to the advantage that the individual insulating boards will set another directly. This avoids heat bridges where heat is escaping and through the gaps to the outside lost. When bonding only to be used solvent-free adhesive. The best way to building adhesives and assembly adhesives are suitable.

Before the isolation the basement ceiling is checked for their quality. If it is smooth, you just test if the ceiling needs a pretreatment. For this you move your finger across the ceiling. If traces of color remain or the fingers even auskalken the color, the ceiling must be thoroughly cleaned before insulation and primed - z. As with primer.

A primer is also necessary if the ceiling SANDET or the color already burst open. In such a case, you should brush off the ceiling before with a stiff brush or a broom to remove loose particles before priming. After that, the primer can be applied to the ceiling.

glue insulation panels on the ceiling

First, the ceiling must be cleaned and completely free from impurities and dirt. Then the construction adhesive can be touched. When the amount and mixing ratio, keep to the best of the manufacturer's specifications.

The ceiling is flat and has no unevenness on, you can apply the installation adhesive over the entire surface of the insulation board. Recommended is a toothed trowel (10 x 10 mm) to comb through the mass. The edges of the plates are not coated with adhesive.

Ceiling support with simultaneous insulation

If you want to insulate the basement ceiling using a batten construction, it must be remembered that at the same time the entire ceiling is hung by the procedure. This method of insulation is recommended, therefore, only at high basement ceilings. Crucial is whether a batten structure already exists or not. If not, the slats must be dowelled in the width of the insulating boards in parallel to the ceiling.

Basement ceiling depend

Basement ceiling insulation and insulateAfter the insulation, the ceiling can be covered

  • drilling machine
  • dowel
  • screw
  • float
  • notched trowel
  • adhesive filler
  • mortar bucket
  • mixing paddle
  • insulation boards
  • Vapor barrier film
  • Bedstead construction
  • Ceiling covering (panels, gypsum or wood plate)

Then you push the insulation into the gaps. If the layer of the Latte series completed, has a so-called battens are attached, d. H. the further bar rows are mounted transversely to the first battens. These bar row is filled with the insulating material.

Should the ceiling be less than an unheated room - such. As a garage - you can still sets last one Vapor barrier film out. This layer verhindet the penetration of moisture into the insulation layer. Lastly, slats and insulation with a ceiling panel covered. Highly suitable panels, plaster or wood panels.

design options

The possibilities are after the basement ceiling was insulated, depends on how much money invested and what material should be used. If you want to use any wood panels or plasterboard for lining the basement ceiling, can on spreadable insulation panels recourse. After processing the plates with a good solid color can sweep. They can also be repaired with a little filler with smaller damage.

Other ideas for the basement ceiling, there are ceiling design for the ceiling.

prevent mold in the basement insulation

Many homeowners assume that Keller are not suitable for insulation due to the high humidity. They fear that behind this mold forms on the wall. However, this concern is unwarranted. It only has to be made sure that the insulation material used permeable is.
