Abstract: A solar panel system wherein solar panels are arranged on the soil, substantially in parallel with the ground surface, and at least some interspaces between the solar panels are provided with a board or boards of thermal insulation material substantially in parallel with the ground surface. A cooling pipework of the solar panel system is arranged underneath the solar panels and the boards of thermal insulation material in the soil. A cooling pipework is further arranged in at least some of the boards of thermal insulation material on the ground surface, and/or is connected to heat distribution boards on top of the boards of thermal insulation material on the ground surface.

Abstract: Sheet of insulating plates comprising successively placed lamellae of insulating plates attached to each other at their edge side which is cross directional in relation to the longitudinal direction of the sheet of insulating plates, alternately at the upper corners and lower corners of the cross directional edge sides, whereby thus formed uniform sheet of insulating plates comprising several lamellae of insulating plates can be folded into accordion-like folded stack of lamellae of insulating plates and unfolded again into a uniform sheet of insulating plates, which sheet of insulating plates has an upper surface and a lower surface. The upper surface of the sheet of insulating plates comprises a surface layer which is arranged in the longitudinal direction of the sheet of insulating plates alternately attached to and detached from the lamellae of the insulating plates in groups of two successive lamellae of insulating plates.

Abstract: A method for recycling polystyrene in a dissolution recycling process, in which method 1,3-dioxolane or isoamyl acetate is used as a solvent for dissolving polystyrene.

Abstract: Roof structure, which comprises load bearing roof beams, the longitudinal direction of which roof beams defines the width direction of the roof, roof boards and a first fastening profile and a second fastening profile, which lock to each other in the joint between two roof boards arranged against each other, whereby the first roof board comprises a first fastening profile and the second roof board comprises a second fastening profile, and which fastening profiles are substantially perpendicular to the load bearing roof beams, and which fastening profiles are continuous along the distance between at least two adjacent load bearing roof beams. Furthermore, the invention comprises a roof element suitable to be used in a roof structure.

Abstract: The insulation tile comprises a first planar surface, a second planar surface and side surfaces defining the surfaces, and a casting compound layer as well as an insulation material layer, which is manufactured from thermal insulation material, the compression strength of which is at least 10 kPa. The casting compound layer forms the first planar surface of the insulation tile and the insulation material layer forms the second planar surface of the insulation tile. Furthermore, the insulation material layer of the insulation tile comprises grooves in the area of the planar surface which will be against the casting compound layer. The insulation tile according to the invention can be used in floor, roof and wall structures.

Abstract: A method for manufacturing an insulation block, preferably an insulation plate, in which method the casting mold is adjusted to a desired size by moving at least one wall of the casting mold, the pre-expanded polystyrene, polypropylene or polyethylene beads are led to the casting mold, the pre-expanded polymer beads are steamed in the casting mold, and the formed finished insulation block is removed from the mold. In a method according to the invention at least one wall of the casting mold is moved during the steaming and/or during the cooling phase after the steaming.
