Underground garage insulation and basement ceiling insulation
Inner-city construction with office buildings and businesses can hardly be imagined anymore without underground parking garages. The requirements for the layout and construction of these spaces are high: statutory regulations for fire protection, energy regulations in the area of thermal insulation, profitability, and a customer-friendly ambience. Ceiling insulation by Multipor offers an optimal solution with excellent fire protection, thermal insulation, and sound insulation, while also reducing construction time and cost. The light-colored surface of the Multipor mineral insulation board creates a bright and friendly mood in the parking garage.
The Multipor ceiling insulation system is also a good fit in the area of basement ceiling insulation in existing or new buildings. An improved room climate on the ground floor and a minimized thermal loss through the basement ceiling ensure an energy-optimized living area and maximum housing health.
Multipor ceiling insulation: mineral and ecological
The Multipor mineral insulation board is an ecological, completely mineral insulation material based on the natural raw materials sand, lime, cement, and water, mixed with a pore generator. These contents make Multipor into an ecologically friendly, toxin-free building material. The mineral boards are manufactured in a closed circuit that is 100% sustainable and economical, from the natural resources used, to production, and finally disposal. This high degree of environmental friendliness has been certified by the German Institute of Construction and the Environment (IBU). In addition, Multipor has been awarded the natureplus quality certificate as a sustainable and future-ready product. The exceptional longevity and the sustainable quality of the Multipor ceiling insulation systems also contribute to its positive eco-balance.
Safety first: Fire protection
In underground parking garages, the subject of fire protection is a top priority. Multipor mineral insulation boards are non-flammable building materials of building material Class A1 and offer the highest degree of safety in basement level rooms. In combination with Multipor lightweight mortar, the insulation system will remain stable in the event of fire –Multipor will not generate any toxic gases or smoke. The material will not drip and is therefore perfect for the insulation of exit routes. The full-surface bonding of the system ensures that there will be no airflow, and therefore no oxygen, between the concrete ceiling and the insulation material – an additional increase of fire protection in underground garages and basement rooms.
Apart from ceiling insulation in new buildings, the insulation boards are also perfectly suited for the improvement of fire protection on existing concrete ceilings. Insufficient fire protection on existing ceilings can be remedied by the application of Multipor ceiling insulation systems – the insulation material will thereby contribute to the classification of the respective ceiling boards into the corresponding fire protection class.
Sustainable, long-lasting, economical
Multipor ceiling insulation systems can be processed quickly and easily; properties that will be especially apparent on the balance sheet. The light weight of the insulation boards has a positive effect on the amount to be processed and also facilitates the rapid installation with bonding mortar on underground garage and basement ceilings. By cutting to fit and sanding on site, curves and projections can be insulated without a problem. The quick processing and rapid drying time of the insulation material ensure very limited downtime of the spaces that are to be insulated. Underground garages can be used again soon. Multipor ceiling insulation systems are long-lasting, of high quality, and impress with their optimal price-performance ratio.

What are the substrate requirements for a ceiling insulation with Multipor sein?
Multipor ceiling insulation can be applied on mineral substrates. The substrate must be load-bearing, dry, and free of any adhesion-reducing residue. Paint, dirt, and non-load-bearing plasters must be removed. Uneven areas and faults can be evened out using Multipor lightweight mortar. Existing concrete burrs must be removed.
More about this in the insulation manual, starting on page 169
How is Multipor ceiling insulation fastened?
Multipor mineral insulation boards are bonded with Multipor lightweight mortar across their entire surface. The Multipor lightweight mortar is applied to the rear of the Multipor mineral insulation board, then notched using a notched trowel.
As of an insulation material thickness > 160 mm, Multipor ceiling insulation is additionally fastened to the substrate with approved Multipor screw anchors.
If the Multipor mineral insulation boards are reinforced and plastered, then as of an insulation material thickness > 160 mm, they must also be additionally fastened with Multipor screw anchors. The fastening is performed "wet on wet", through the fresh reinforcement layer. For this purpose, the reinforcement mesh must be carefully slit with a cutter knife.
Joints at the transition to adjacent building components
In order to prevent potential damage to the insulation layer, the Multipor insulated ceiling must be separated from adjacent building components such as walls or pillars by a circumferential joint - possibly by cutting with a saw. You'll find additional information in our detail drawings.
What is used to anchor Multipor ceiling insulation?
Multipor mineral insulation boards should be fastened with appropriate anchors – with or without fire protection requirements. In case of fire protection requirements, Multipor mineral insulation boards must be anchored using Multipor ceiling fasteners. If there are no fire protection requirements, Multipor screw anchors may be used.
What surface finishes are possible with Multipor ceiling insulation?
The individual surface finish depends on what is desired and on the requirements.
- colored coating with Multipor interior silicate paint
- full-surface skim coating with Multipor lightweight mortar, 2 - 3 mm thick
- full-surface plastering, incl. reinforcement layer of Multipor lightweight mortar and Multipor reinforcement mesh. Multipor lightweight mortar can be applied and felt-brushed as a topcoat, or alternatively, the reinforcement layer can be smoothed with a thin layer of Multipor lime finishing plaster. In this case, anchoring is usually required.

Up to what thickness can Multipor be applied in a single layer?
Multipor can be applied in a single layer up to an insulation material thickness of 200 mm.
Can Multipor ceiling insulation be applied in a double layer?
As of a minimum thickness of 120 mm, Multipor ceiling insulation can be applied in a double layer? When double-layering, the first layer of insulation material must be additionally fastened with Multipor screw anchors. The second thinner or equally thick layer of insulation material should be bonded with Multipor lightweight mortar. If the Multipor mineral insulation boards are being reinforced on the underside and plastered, both insulation layers should be anchored "wet on wet" through the reinforcement mesh and into the load-bearing substrate. As of an insulation material thickness > 200 mm, Multipor mineral insulation boards are generally always applied to the ceiling in a double layer.

How is a joist insulated using Multipor ceiling insulation?
When insulating joists, make sure to insulate the underside of the joist first, then the side surfaces.
If the bonding agent for the underside of the joist is applied to the mineral insulation board, the projecting areas will remain free. This prevents the horizontal and the perpendicular Multipor mineral insulation boards being bonded to each other, and the mineral insulation board potentially tearing in case of bending.
The insulated ceiling surface abuts the side of the joist insulation. Dependent on fire protection requirements, this joint should also be unconstrained and permanently elastic. For the connection of the joist insulation to the walls, the application guidelines applicable to the use of expansion joints and movement joints must be observed.
More about this in the insulation manual, starting on page 176
Do movement joints have to be taken into account in a Multipor ceiling insulation?
Movement joints (expansion joints) in the load-bearing substrate must be transferred into the insulation material layer. Under no circumstances should existing joints be covered by insulation, as this may lead to damage in the area of the insulation layer in case movement occurs in the building structure.
