Description

[0034] The drawings show:

[0035] FIG. 1 top view of a section of a frieze tape for attachment to a ceiling according to the invention;

[0036] FIG. 2 side view of the frieze tape shown in FIG. 1; and

[0037] FIG. 3 perspective view of a ceiling having a frieze tape applied thereto forming a perimeter.

[0038] In FIG. 1 a section of a frieze tape 1 for attachment to a (acoustic) ceiling is illustrated. Such a section for example can be cut from a roll in which frieze tape 1 is available in the market. Frieze tape 1 comprises a layer of permeable non-woven material 2 and an adhesive layer 3 attached to the non-woven material 2.

[0039] The application of the illustrated frieze tape 1 to a layer of building boards requires no liquid adhesive during the installation so that the application is clean and no pre-arrangements, like covering the floor, are required before the installation.

[0040] In the shown example, the non-woven material comprises synthetic fibers which provide dimensional stability. The grammage of the non-woven is in the illustrated example in the range of 10 to 70 g/m.sup.2. The permeable non-woven material 2 has a thickness of 8 to 40 μm while providing an air permeability in the range of 1000 to 15000 l/(m.sup.2s).

[0041] The adhesive layer 3 is arranged at one side of the non-woven material 2 in a regular pattern of glue dots 31. In the illustrated example, the adhesive layer 3 has a weight of 3 to 60 g/m.sup.2. The pattern comprises glue dots 31, preferably of an identical size, which are arranged in an amount in the range of 25 to 15625 glue dots per 625 mm.sup.2. The adhesive may be a hot melt adhesive made of an UV-light curable acrylic polymer material.

[0042] The circular area 2 shows an enlarged section of the frieze tape 1 in the top view. It illustrates areas 21 without adhesive applied thereto and glue dots 31.

[0043] In a particular example, the frieze 1 tape as shown in FIG. 1 is made of a non-woven material 2 “Vlies VILEDON T 1790C” available in the market from Freudenberg Vliesstoffe/Weinheim consisting of 100% glass fiber, 30 g/m.sup.2 weight/area and an air permeability of about 8.000 l/(m.sup.2×s) (measured with AKUSTRON from rycobel group ib-walther/Uffenheirn).

[0044] An adhesive layer 3 is applied to the exemplified non-woven material 2, the adhesive layer 3 having a weight/area in the range of 2.0 to 2.5 g/m.sup.2 and is a hot melt adhesive e.g “Technomelt 8783” from Henkel/Dusseldorf. The adhesive layer 3 is applied with a 20 dpi-pattern of glue dots 31 so that the air permeability of the adhesive layer 3 is about 6.000 l/(m.sup.2s) determined by the above mentioned AKUSTRON device. The frieze tape 1 has in this specific example a width of 100 mm.

[0045] The adhesive layer 3 can be covered and protected by the silicone layer of a one side siliconized paper (not shown), e.g. RB065/2 from Cotek Papers Ltd/Draycott, Great Britain, in order to allow for rolling up of the frieze tape. The protective siliconized paper has to be removed before applying the frieze tape to a ceiling or a wall.

[0046] The particular combination of non-woven material 2 and adhesive layer 3 that is shown in FIG. 1 is preferred, but generally the non-woven material 2 and the adhesive layer 3 can be combined without restriction within the above mentioned ranges.

[0047] In FIG. 2 a side view of a section of the frieze tape 1 for attachment to a ceiling or a wall is illustrated. In the side view, as well, can be seen that the frieze tape 1 comprises a layer of permeable non-woven material 2 and an adhesive layer 3 attached to the non-woven material 2. In the circle 2 below, an enlarged section of the frieze tape 1 is illustrated in the side view which gives a detailed illustration of the thickness of the adhesive frieze tape 1 which can be in the range of 15 to 80 μm and the thickness of the permeable non-woven material 2 which is in the range of 8 to 40 μm.

[0048] In FIG. 3, the frieze tape 1 explained in connection with the foregoing figures is attached to an acoustic ceiling 10 having a frieze section 11 extending along its perimeter.

[0049] The ceiling 10 is installed by the method described herein which starts with providing a (plurality of) perforated building panel (s) to form the ceiling surface.

[0050] Thereafter, adhesive frieze tape 1 is applied in selected areas for selectively covering areas of perforations of the building panels 10. The selected areas constitute the frieze section 11. The areas as shown in FIG. 3 may form a frame around the ceiling. However, it is also possible to arrange covered areas within the ceiling surface for merely optic purposes, for example creating a certain design.

[0051] Thereafter paint is applied to the attached frieze tape 1 and at least part of the ceiling surface (uncovered building boards) to firmly attach the frieze tape 1 to the building boards and to obscure the edge of the tape. Finally the edge (area) of the frieze tape 1 can be sanded.

[0052] In a specific example, the frieze tape is attached to an acoustic ceiling made of plasterboards which are available in the market as CLEANEO CLASSIC 8/18R (Knauf Gips KG/Iphofen).

[0053] The applied frieze tape is covered by the paint KNAUF INTOL (Knauf Gips KG/Iphofen).
