摘要:
Methods of forming insulation mats including: providing a mixture of fibers comprising first inorganic fibers and second inorganic fibers, wherein the first inorganic fibers shrink by no more than about 2 percent and the second fibers shrink by about 5 to about 15 percent when the mixture of fibers is heat treated; wet-forming a web of fibers from the mixture of fibers; entangling the web of fibers to form an insulation mat; heat-treating the insulation mat; and drying the web of fibers and/or the insulation mat after said wet-forming and prior to or during said heat treating; and wherein the insulation mat includes substantially no non-fibrous binder material prior to said heat treating the insulation mat at a temperature of from about 500°C to about 800°C, optionally for at least about 3 minutes. Insulation mats manufactured according to the above methods.

摘要:
An flexible heat insulation product (1) comprising a flexible heat insulating core layer (4) with a first side (3) and a second side (9), and a flexible facing (2) that is connected to the first side (3) of the insulating core layer (4) by a plurality of elements (7) that extends from the facing (2) to the second side (9) of the insulating core layer (4). The insulation product (1) further comprises a flexible heat insulating cover layer (8) that is secured to the second side (9) of the insulating core layer (4). A method for producing such a product is also disclosed.
摘要:
A fibre mat has plant-derived fibres arranged in a fibrous network and a plant-derived material, different from the plant-derived fibres, held within the fibrous network. The fibrous network comprises an array of linked fibres, the fibres each being substantially single fibres. The mat also has a heat activated binder component. Also disclosed are methods for forming the fibre mat and fibre panels formed from fibre mats.

Cet écran d'isolation thermique est constitué d'une structure textile intégrant un film réalisé en matière plastique (301). Le film plastique (301) est renforcé au moyen de fils textiles de renfort (304, 305), solidarisés audit film au moyen d'un fil de liage multibrin (303) venant mailler lesdits fils de renfort par tricotage de part et d'autre de la surface constituée par le film plastique.
摘要:
An intermediate insulating product (20) is disclosed comprising a planar insulating layer (11 ) having a top side in to which is formed a plurality of parallel channels (14) having cross-sections with tapered sides. A vapour proof layer (18) is applied to the top surface after the channels (14) have been formed such that the vapour proof layer (18) bridges the plurality of parallel channels (14). The intermediate insulating product (20) is then bent with mechanical manipulation in regions adjacent the bottom of the channels (14) thereby causing the channels (14) to close to form a non- planar, derivative insulated ductwork product and the vapour proof layer (18) forms a vapour proof inner lining (18) to the derivative insulated ductwork product (30).
