Aerogel A2f

Installation guidelines


Handling and Storage

AEROGEL A2f are 1000x1480 mm size boards provided on pallet (Fig.1.a). 

AEROGEL A2f should be protected from moisture; wet boards should be allowed to dry out completely on a level surface before use. The stacking of boards on their edges can lead to deformation of the boards and damage to the edges. Boards should generally be carried upright and the use of board lifters is advised when ftting boards to ceilings (Fig.1.b).

  Fig.1.a    Fig.1.b

Before starting installation please check availability in-site of the necessary equipment listed here.



AEROGEL A2f can be machined and cut with ease. Special tools are not required. Standard tools which are normally used for dry lining work are right.

Proceed with cutting outside the rooms, in open environment. If it is not possible, confine working area and to ensure enought ventilation.

Cutting of panels shall be done

1. by hand, with the engraving & breaking technique by using fibreboard scoring knife HF5908 or

2. by circular saw.

Main steps for hand cut are the follow:

Fig.2.a | Place AEROGEL A2f on the work table with insulation side at view. By using a straight edge or similar tool, with a pencil mark on the surface the cutting line; 

Fig.2.b | Use a grinder with cutting disc 1.0 mm-thickness to cut the insulation layer along the cutting line, or aid by the straight edge. Cut the insulation layer entirely, until tap the panel;

Turn the board

Fig.2.c, Fig.2.d | On the other side -gypsum board at view- engrave the panel with the fibreboard scoring knife HF5908 , or if not available by using a strong cutter. Perform the scoring in two or more steps, using a straight edge or similar tool;

Fig.2.e | Place the engraved line section on the edge of the working table: the larger board section is clamped down and the protruding section is then broken over the edge;

Fig.2.f | If needed cuts can be be finished by use of abrasive paper or scraping knife.

For non-linear cuts - such as, for example, corners or special shapes - it is possible to use electro-tools such as alternative saw or circular saw with vacuum cleaner. In this case, it is important to cut the corresponding insulation layer section on the back of the board before proceeding with the cut of fibreboard component. 


Wall/ceiling conditions

Before proceeding with the installation make sure that wall is plastered and finished, planar, free of irregularities, dry, not subject to rising damp, free of efflorescence and molds.

If going to install AEROGEL A2f on an old plaster, make sure that well anchored; otherwise relevant irregularities must be removed and restored. Old paint as long as healthy and well anchored can be not removed.

Uneven walls or parts, deteriorated or inconsistent, could compromise the seal of the anchors. In this situation it is advisable to perform some tests at different points and study results.



AEROGEL A2f may be installed on sipport frame or in adherence to the wall without the need of support frame. Maximum height of the counter-wall must not exceed 3,5 mt.

Laying scheme is with short edge placed horizontally and full-height vertical joints. Horizontal joints shall be spaced by at least 200 mm. Cross joints are not allowed (Fig. 3).

Lower panels are placed on a thin elastic support, such a synthetic separation strip.

AEROGEL A2f shall be installed at a distance of approx 6-7mm from all the adjacent elements (ceiling and partition walls), thus cutting of the panels will be made considering that 6-7mm gap.

Contact between AEROGEL A2f and adjacent building elements shall be avoided.

  Fig.3    Fig.4

Cutted side should be placed to ceiling,floor or wall so all joints between panels will be tapered edge provided.

Tapered edge panels shall be installed in direct contact without leaving gap (Fig. 4). 1-2mm gap is however allowed. 

Where installataion of two panels with different edges will be needed -one tapered and one cutted- a gap of 6-7mm between of two is necessary.



Before start with AEROGEL A2f installation, apply a strip of tape with fuction of separation element in correspondence of walls and ceiling connection points. See technical details in point 1.1.

If necessary or foreseen, apply of gypsum-based adhesive on the insulation layer by plots or total surface application is possible. Adhesive supports but does not replace the mechanical fixing.

Place the first AEROGEL A2f board as picture, with the short side on the strip on the floor and leaving a 6-7mm gap from the side wall if existing (Figure 3). Check the verticality and adjust if necessary. Correct installation of the first panel will make easy the installation of all next ones.

By use of a power drill makes holes and proceed with insert nr. 8 frame plugs/m2 (=nr.12 per panel) and screws, with a distance of approx 25mm from the edge (Fig. 4). Start by the central screws and continue with along the edges. During drilling operations the use of vacuum cleaner for dust extraction is recommended.

  Fig.4    Mov.1


We recommend the use of Ø8mm nylon frame plug with flathead screw as art. MQL-ST. 

Length of the plugs must be choose depending on the characteristics of the wall (material, consistence, thickness, presence of cavities) and on AEROGEL-HF thickness too. Check the "max. fixable thickness" value for the plug, usually indicated as "tfix".


The head of the screws must be slightly inside of the panel. Hammer the plug into the hole until it is placed 3-4mm inside the panel.

After clamped the screw, the head will be placed approx 2mm inside the panel to allow covering them with joint filler (Mov.1).


Edge jointing

It is recommended to clean the surfaces of powder residue before proceeding. Joints must be clean and free from dust before filling.

For filling tapered edge joints, gaps between panels and covering screw heads, use Joint Filler art. HF5901 . It needs to be applied on two hands. Paper Jointing Tape art. HF5906 must be embedded in the first layer of Joint Filler. 

The edge jointing method differs depending on the joint is made by Two factory-made tapered edge boards or One factory-made tapered edge and one edge cut on-site:


Reinforcement tape needed.

Paper Jointing Tape art. HF5906 must be embedded in the first layer of Joint Filler. The first hand of Joint Filler shall be dry before the second hand.

Please Note: Tape must be well integrated into the filler, otherwise it is possible have formation of air bubbles in the back side of the tape during drying. So, tape needs not be in contact with panel, but embedded in the filler.


Reinforcement tape unneeded.

Joints must have adequate gap of 6-7mm that will be filled with Joint Filler.

Joint Filler should be pressed into the joints to the full depth.

In order to ensure adhesion to both board edges, the filler is pressed against the board edge and scraped to the opposite edge (herringbone pattern). The countersunk heads of the fixings and any damage is also flled at the same time. Any unevenness can be sanded down once the first fill has dried (mesh or sand paper, min. 160 grain/grit). Once the sanded dust has been swept away, fine finishing can take place.



Surface finishing

After the cleaning of surfaces, AEROGEL A2f is ready to be covered by most common interior finishe layers:

- thin plaster by Fine Surface Treatment (Mov. 2)

- plasters

- decorative thick plasters 

and, thereafter, 

- thin paints

- covering by panels/tiles

- wallpapers


Before to any fnishing work the surface must be assessed for suitability. The surface including the joint must be dry, solid and free of dirt and dust. In particular please ensure that

- splashes of gypsum, mortar etc. are removed
- scratches, indentations, etc. are flled with Joint Filler
- all filled areas are smooth and sanded if necessary

Important notice: AEROGEL A2f is supplied with surface sealed at the factory. Additional undercoats and primer coatings are only required if stated by a system manufacturer for use with gypsum-based supports, f.e. for thin or textured plaster and tile adhesive.

- Finishing stucco

With regards to the most common finishing solution the product should be worked at a temperature of not less than 5°C.

Thin plaster must be applied in the thinnest layer possible. The maximum thickness of each hand should be approximately 0.5 mm. Typically it is applied in a minimum of two coats.

Small irregularities can be sanded using abrasive screened or sandpaper. Before any further finishing surface must be newly cleaned from dust.

The Fine Surface Treatment is a necessary layer before paints and wallpaper application. It is not needed for coverings solutions or plasters.


On AEROGEL A2f all types of ceramic tiles and synthetic materials tiles can easily be applied using the thin-bed method.
Check instructions of manufacturer of adhesive before use a dispersion and reaction resin adhesives or polymer- modified cement powder adhesives on gypsum-based supports. Specifically, check if a primer is needed.

Low-moisture and flexible tile adhesive should be used, f.e. polymer-modified cement powder adhesive.
The tile must be have at least 80% of the surface in the adhesive bed. Flexible grout should be used for the grouting.

In the case that AEROGEL A2f is installed in areas which are exposed to moisture -f.e. shower and bathtub areas, wall-floor edge- it must therefore be protected against moisture: first of tile application, apply an additional water-proofing: complete waterproofing systems or liquid sealants sheaths with plastic additives can be used.

Primer coating is needed before water-proofing treatment.

Please refer to your local building regulations and guidelines for waterproofing systems with regard to any specific application. The illustrated waterproofing areas are an example of surfaces that usually require water-proofing treatment. 

Areas behind showers and bathtubs must be protected against the penetration of water to a height of min. 2.20ml. The waterproofing should extend at least 30cm above the shower head for fixed shower rails.

System sealing tapes, sealing corners and pipe penetration patches must be applied to wall/wall and wall/floor edge junctions and connection joints. Furthermore, the entire base area of the walls in a room with a shower or bathtub should be waterproofed to protect against any moisture rising from the floor.

In any case please follow the installation instructions of the manufacturer of the water-proofing system.




Technical details



1. Joints and corners

1.1 Jointing with existing elements

The point of connection with walls/ceilings and in general with elements made of different materials from gypsum fibreboard (bricks or cement plaster, concrete, steel, wood) must be worked by a clear separation between the different construction materials in order to avoid formation from cracks.

Before start AEROGEL A2f installation, apply a strip of tape as f.e. Trennfix or similar on walls or adjacent elements.


After installed the panels keeping a gap of 6-7 mm, fill the gaps between panel tape.

Excess of tape will be removed with cutter only after all jointing and finishing works.

In this way there will be no risk of cracking in the joint.

Before surface finishing -f.e. painting- apply on the entire perimeter a paintable acrylic sealant, then smoothing it by finger.





1.2 Corners/1

In order to ensure a good connection between two panels at 90° corner, please to remove a strip of insulation material from the rear side one of the two panels by cutter. The strip will be wide as the second panel thickness.

Install panels leaving a small gap of 1-2 mm that will be filled with Joints Filler.

Place the galvanized steel corner on the corners. The steel corner may be fixed by screws and/or on a layer of Joints Filler.

Apply one or more hands of Joint Filler in order to have a perfect surface.


1.3 Corners/2

Install the first AEROGEL A2f panel (dx panel on the picture), leaving a gap of 6-7 mm from the adjacent wall that will be filled with Joints Filler.

Install the second AEROGEL A2f panel (sx panel on the picture), leaving a gap of 6-7 mm too from the adjacent panel that will be filled with Joints Filler.

On the corner area, apply Joints Filler for at least 50 mm on both panels and place in the Paper Jointing Tape by folding at 90° along the center line.

Apply one or more hands of Joint Filler in order to have a perfect surface.



2. Fixing points loads 

Light point loads that run vertically parallel to the wall surface can be fixed directly to AEROGEL-HF body. These can be fixed with suitable, simple commercial fixing components. For example nails, picture hooks with single or double nail fixing or screws and dowel (toggle fixings) are suitable for this purpose. Details on the load-carrying capacity of fixing components can be found below.

 18 Kg   28 Kg  38 Kg  30 Kg  55 Kg


Heavy loads as f.e. shelves, furniture, cabinets, brackets, shelves etc. must be fixed to the brick/cement structure through effective frame plugs.
