Description

METHOD OF INSULATING A ROOF AGAINST SOUND PENETRATION AND/OR EMANATION
The present invention relates to a method of insulating a roof against sound penetration and/or emanation, wherein the roof comprises a substructure, clips spaced at intervals over the substructure and metal panels which are fixed over the clips, wherein the substructure comprises a support layer, a vapour barrier layer and an insulation layer and also relates to a roof construction having a substructure, clips spaced at intervals over the substructure and metal panels which are fixed over the clips, wherein the substructure comprises a support layer, a vapour barrier layer and an insulation layer. The invention further relates to a roof construction. Such a method is known from the utility model DE-20309933-U1 , wherein there is provided an insulation layer functioning as a thermal insulation layer. It is known in the art to insulate roofs of buildings against sound penetration and/or emanation by laying gypsum panels or boards on the substructure of a roof.
However, the occurrence of gaps or cracks between the gypsum panels is often unavoidable and reduces the effectiveness of the sound proofing provided by the panels. This is particularly the case for curved roofs. It is an object of the present invention to provide an improved method for insulating roofs against sound. It is a further object of the present invention to provide an improved method for insulating curved roofs against sound. It is another object of the present invention to provide a method of insulating roofs against sound which uses sound insulating material efficiently. It is another further object of the invention to provide an improved roof construction. One or more of these objects are achieved by coating at least part of at least one of the layers from which the substructure is comprised with liquid sound insulating material which hardens on setting and that at least a part of the liquid sound insulating material is directly coated on to the vapour barrier and/or on the thermal insulation layer. The method of the present invention has several advantages over the known method of laying gypsum panels on the substructure of the roof. By using liquid insulating material which hardens on setting the liquid material can be spread evenly over the whole surface without gaps or holes in the coverage of the sound insulating material. The liquid insulating material can also easily follow the form of even complicated roofs unlike panels which may require fixing onto more complicatedly shaped roofs. The thickness of the insulating material can also easily be tailored to the requirements for each particular roof and also for specific areas within one roof. The liquid insulating material can be pumped up to the roof substructure at the desired rate unlike panels which have to be lifted up and once on the roof substructure the liquid material is easier to handle and distribute than the conventional panels which are breakable and heavy. The present invention also avoids the problem of having a heavy pile of panels positioned on the substructure of the roof awaiting distribution over the roof. The liquid insulating material preferably comprises cement material to aid the setting of the liquid material and/or gypsum. The cement material may form part of a concrete mix comprising aggregate and cement. Gypsum has good sound insulating properties and is relatively easily available in powder form. Gypsum may make up the majority of the sound insulating material. Alternative materials which harden on setting include plaster or polymers such as polyester resin or polyurethane foam. The liquid sound insulating material is preferably provided with reinforcing means to strengthen the layer against breaking and cracking. The reinforcement can be provided by, for example, an reinforcement layer made of metal or plastic mesh e.g. chicken wire or cribbing wire embedded in the liquid insulating material. Alternatively or in addition the liquid insulating material may comprise reinforcing polymer fibres. The liquid insulating material may also be applied in combination with panels of insulating material such as e.g. gypsum board to provide reinforcement. In the method of the invention the viscosity of the liquid insulating material is preferably adapted in accordance with the steepness or curvature of at least one of the layers from which the substructure of the roof is comprised. This enables the method of the invention to be used on a wide variety of roofs without the liquid sound insulating material sliding off the roof. Preferably two or more layers from which the substructure is comprised are at least partly coated with liquid sound insulating material to improve the sound insulation. The present invention also relates to a roof construction having a substructure, clips spaced at intervals over the substructure and metal panels which are fixed over the clips, wherein the substructure comprises a support layer, a vapour barrier layer and an insulation layer wherein at least part of at least one of the layers from which the substructure is comprised is coated with liquid sound insulating material which has hardened on setting on the substructure and that at least a part of the liquid sound insulating material is directly coated on to the vapour barrier and/or on the thermal insulation layer. The roof construction has one or more of the advantages as set out above. The sound insulating material on the substructure may comprise cement material and/or gypsum, thereby obtaining one or more of the advantages set out above. The sound insulating material on the substructure may also be reinforced by one or more of the alternatives given above thereby having one or more of the advantages described above. Two or more layers from which the substructure is comprised may be coated at least partly with liquid sound insulating material which has hardened on setting on the roof substructure thereby giving one or more of the advantages described above. The present invention is described further by way of example with reference to the accompanying schematic figures. Fig. 1 shows a cross section through a roof construction made using the method of the invention. Fig. 2 shows a perpendicular cross section along line A through the roof construction of Fig. 1. The roof construction shown in cross section in Fig. 1 comprises a substructure made up of a support layer in the form of a trapezoidal sheet 1 made from e.g. steel, a vapour barrier 2 coated with e.g. bitumen positioned on the trapezoidal steel sheet and an insulation layer 4. Metal clips 6 (of which one is shown) are affixed to the vapour barrier 2. The outer layer of the roof construction is made up of metal sheets 5,7 which are attached over the clips 6. Liquid sound insulation material such as e.g a mixture comprising gypsum powder and water is coated on to the vapour barrier 2. The liquid sound insulation material sets to form a hard layer 3 of sound insulating material. The layer 3 is preferably approximately 1-5 cm thick. Once the layer 3 has set a layer of fibrous thermal insulation 4 can be installed and the metal sheets 5,7 attached to the clips 6 to complete the roof construction. As can be seen from Fig. 2 the metal sheets 5,7 are folded or zipped over the head portion of the clip 6. The layer 3 may also include a layer of steel or plastic mesh which is embedded in the layer 3 and provides reinforcement to strengthen the layer 3. More than one layer making up the substructure of the roof may be coated with liquid sound insulating material. For example, the vapour barrier may be coated with a layer of liquid sound insulating material which is subsequently covered with a layer of thermal insulation material (such as mineral wool) before coating a layer of liquid insulating material onto the thermal insulation layer. The substructure of the roof may comprise more than one layer of insulation material such as thermal insulation material. Having now fully described the invention, it will be apparent to one of ordinary skill in the art that many changes and modifications can be made without departing from the scope of the invention as hereon described.
