1. Technical Field
The present application relates to a building having a roof with structured roof tiles and a structure projecting out from the roof surface, such as a chimney, a window, a wall, or ventilating pipe and to a method of constructing a roof of a building covered with structured roofing tiles and a structure projecting out from the roof surface, such as a chimney, a window, a wall, or ventilating pipe and also the gap between a ridge, an arris or hip covering. The present application further relates to stretchable band material with at least one supporting layer and one covering layer, the band material showing a multiplicity of folds whose edges extend crosswise to the stretching direction and substantially parallel to each other. Such a band material is able to mould round textured surfaces showing unevenness, curvatures or spherical convexities and is used for packaging and sealing purposes.
2. Background Information
Methods are known for constructing a roof of a building covered with structured roofing tiles and a structure projecting out from the roof surface, such as a chimney, a window, a wall, or ventilating pipe and also the gap between a ridge, an arris or hip covering which covers the surface of the roof of a building covered with structured roofing tiles and a structure projecting out from the roof surface, such as a chimney, a window, a wall, or ventilating pipe, and also the gap between a ridge, an arris or hip, etc. In these cases the surface of the roof of a building covered with structured roofing tiles and a structure projecting out from the roof surface, such as a chimney, a window, a wall, or ventilating pipe, and also the gap between a ridge, an arris or hip, etc., the area between an essentially planar surface or straight edge and a three-dimensional structured surface must be covered whereby the three-dimensional, structured surface is larger than its projection into the plane. The covering must therefore be extendable in at least that region abutting the three-dimensional, structured surface.
Upon constructing a roof of a building covered with structured roofing tiles and a structure projecting out from the roof surface, such as a chimney, a window, a wall, or ventilating pipe and also the gap between a ridge, an arris or hip covering, such covering material in the form of sheets, strips or widths is required as covering on the roof of a building, for example, to seal the gap between the surface of the roof covered with structured roofing tiles and a structure projecting out from the roof surface, such as a chimney, a window, a wall, or ventilating pipe, or also the gap between a ridge, an arris or hip, etc. In these cases, the gap between an essentially planar surface or straight edge and a three-dimensional structured surface must be covered so as to be water-tight, whereby the three-dimensional, structured surface is larger than its projection into the plane. The covering must therefore be extendable in at least that region abutting the three-dimensional, structured surface.
Such a band material is known from the document DE 195 23 834 A1. It concerns a stretchable covering material which can be manually distorted in at least one direction, comprising an extensible supporting element showing breaches, and a surface covering coating, said supporting element showing at least on its upper side a coating of thin flat material bound to it and the coated covering material being compressed in an opposite direction with respect to the stretching direction. In practice the supporting element comprises soft-annealed aluminium in the form of a grid of expanded metal with corrugated ridges. Said grid is coated with a skin of extensible plastic material for sealing purpose, which is applied to non-woven material. The non-woven material provided with the skin forms the surface covering coating of the supporting element. The waterproof covering of a surface by means of this covering material is due to the plastic skin applied on the non-woven material and carried by the metal grid. The manufacture of this at least three-ply covering material has proved to be relatively expensive because the required metal grid is expensive on one hand, and, on the other hand, it is a sharp-edged expanded metal so that it has to be carefully trimmed before the coating process in order to avoid that the plastic skin might be damaged or pierced.
An object is to create an economical covering material for covering the gap between a planar surface and a structured surface, in particular a highly structured roof surface, which material can be extended in at least one direction. An object also is to provide a waterproof band material which is less expensive than the known covering material and less sensitive.
According to the present application, the object may be realised in that the supporting layer can comprise fibres of organic material, in that the covering layer shows a foil of ductile metal and in that the folds can have the shape of small folds bordering one another in which the additional material needed for stretching may be stored.
The supporting layer comprising fibres of organic material may confer to the band material a high resistance to tearing. Natural fibres, such as wool or silk, as well as such ones of plastic may be taken into consideration as organic material, the length, the diameter, the shape of the cross section and the chemical composition of the fibres being optimally adaptable to the purpose of the application of the band material. Fibres of polyethylene, polypropylene, polyacrylnitrile, polyester or polyamide may be recommended as especially appropriate. The supporting layer may increase the resistance to tearing of the metallic covering layer and may prevent it from a too strong crumpling in the area of the edges of the small folds.
The metallic foil of the covering layer can be plastically mouldable and may not produce any restoring force due to the ductility of the material used so that the band material keeps the shape for instance after moulding around an uneven base and may not intend to come back to its previous shape. Possibly lead, copper or soft-annealed aluminium can be taken into consideration as ductile metals for the metallic foil of the covering layer.
The small folds defined according to the present application may be small folds, about 10 or more of which can be arranged within one centimeter of the band material, possibly 30 or more folds per centimeter. The folds may border one another, edges issuing from clockwise folding alternating with edges issuing from anticlockwise folding. The space between two edges formed by two opposite foldings may not be substantially more than 1 mm and may not always be the same. A fold may not extend over the whole width of the band material, either. The small folds may perfectly be irregular and of different shape. The small folds may be possibly impressed into the originally even two-ply band material, the material being compressed in an opposite direction or diagonally with respect to the stretching direction. The importance of the compression may determine the later possible extension. For example, a band compressed to the half of its previous length can thus be later extended up to just twice the length. The additional material needed for stretching out can be stored in the small folds which can be drawn flat when stretching. It is clear that the maximum stretching may be obtained in the stretching direction extending in a right angle with respect to the edges of the small folds. If the stretching takes place diagonally with respect to the edges of the small folds, the band material can moreover be stretched in a second direction. If, for example, the first stretching takes place with an angle of 45° with respect to the edges of the small folds, a second stretching with an angle of 90° with respect to the direction of the first stretching may be further possible. Thus, opposite to the plane of the not-stretched band material, a cap-shaped bump or a hollow, for example, can be produced.
The band material according to the present application can be used for example for the packaging of objects or sealing of openings, the band material being manually plastically mouldable because of its stretching capacity, as well as adaptable to the surface of the object to be covered and may not spring back to its initial shape.
According to the purpose to which the band material is used, the supporting layer comprising fibers may not only have the shape of a foil, but also of a non-woven fabric, of textile fabric or of knitted fabric, the basis weight being able to vary additionally.
The band material may be very light because the covering layer presents only a thin metallic foil. Consequently, the band material may be not only impervious to light and waterproof but also may be impermeable to steam diffusion.
As far as a waterproof embodiment may not be considered as of importance, but the band material may allow a ventilation, slots may be provided for, possibly transversely to the edges. Advantageously, the slots can be arranged in staggered rows so that the band material can be stretched out transversely to the stretching direction similar to expanded metal.
A particularly cheap and easily mouldable band material may show a supporting layer of polypropylene non-woven material with a basis weight of 10 g/m2 and a covering layer of aluminium foil with a thickness of 7 μm and about 30 small folds per cm. When using a non-woven material of polypropylene with a basis weight of 20 g/m2 and an aluminium foil with a thickness of 20 μm, the optimum number of folds per cm may be 15.
The band material may be particularly easily adaptable to very rugged surface textures when it additionally shows rough waves transversely to the edges of the small folds. The length of the waves could at least be more than 1 mm in order to avoid that the small folds crumple. Thus, the metallic foil may not tear where sharp ridges and/or bottoms are branching off.
The covering layer can additionally show a second ply or more. The outside ply of the covering layer can be optimally adapted to the purpose of application provided for, the outside ply can, for example, prevent from corrosion and be resistant to weathering and/or be coloured. Such a band material can, for example, show a polyester non-woven material with a basis weight of 30 g/m2, and an aluminium foil with a thickness of 20 μm, coated with 10 g enamel per m2, and about 12 small folds per cm.
The band material may be particularly resistant to the weathering and/or resistant to tearing if it additionally shows a coating of plastically or thermoplastically mouldable material. The additional coating can, for instance, comprise bitumen, polyisobutylene, acrylate, polyurethane, hotmelt or a foamed material, possibly such material with high recuperative capacity. An additional coating which swells under the influence of humidity may also be advantageous. This additional coating can possibly be applied on the covering layer, it may still also be applied onto the supporting layer or even on both sides. As the band material can itself be already waterproof, a very thin coating may already be sufficient to obtain special surface properties. The additional coating can also be arranged between the covering layer and the supporting layer. A band material which may be most resistant to tearing shows, for example in the order from the bottom to the top, polyester non-woven material, polyester foil, aluminium foil and enamel.
In order to close an opening it may be particularly easy to fix the band material on the edge of the opening if the band material shows at least on one of its both longitudinal edges a bonding sheet of extensible self-adhesive material. The bonding sheet can be applied in the form of a narrow strip. Thus, the band material can be bound to the base without additional glue, in order to avoid that the coiled up band material sticks together, the bonding sheet can be covered with a protective film which can be withdrawn on the spot.
The bonding sheet may possibly be applied on the supporting layer.
For some purposes of application corresponding preforms out of the band material can be manufactured.

When the word “invention” or “embodiment of the invention” is used in this specification, the word “invention” or “embodiment of the invention” includes “inventions” or “embodiments of the invention”, that is the plural of “invention” or “embodiment of the invention”.
