Abstract
Abstract A roofing plate (10), such as a corrugated, interlocking tile, is at its upper side surface provided with a proofing strip (27) arranged extending across the corrugations of the roofing plate at the upper edge thereof. The proofing strip (27) is constituted by a strip of upright synthetic fibres, such as a combination of polyamide fibres of a length of 3 mm and of a length of 5 mm and of thickness of 0.05 mm (22 dtex). The strip (27) is adapted to provide a barrier when its is clamped between the upper side surface of the roofing plate and the lower side surface of an adjacent roofing plate, and the barrier permits the passage of air from the inside of a loft defined below the roofing plates and out and form the outside and into the loft and further permits the passage of water from the inside of the loft and out, and blocks the passage of water and dust form the outside and into the loft. A further proofing strip (29) may be arranged along one of the edges of the roofing plate extending along the corrugations thereof. The proofing strip (27) may be provided as a single component adapted to be arranged on the upper or lower side surface of a roofing plate prior to the arrangement of the roofing plate overlapping another roofing plate on the roof and may comprise a base layer having a glue layer and a slip paper, if desired. The proofing strip (27) may be applied to the roofing plate (10) in an electrostatical application process (Flock application) and retained in a glue layer of the roofing plate. (FIG. 1).

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
174 words
A corrugated interlocking tile roofing plate having opposite side surfaces and comprising proofing strip means on at least one of said surfaces and extending thereacross, for providing a substantially water impervious barrier while generally providing an air and humidity permiable passageway, said plate being adapted to be arranged on a roof partly overlapping and partly being overlapped by adjacent roofing plates, said roof defining an attic thereunder, and said proofing strip means including a strip of upright synthetic fibres located on said plate on regions thereof which are overlapped by adjacent plates, to provide a fibrous barrier between said side surface of said roofing plate and the opposite side surface of one of said adjacent roofing plates which permits the passage of air in and out of said attic and further permits the passage of humidity to escape to outside said loft but substantially blocks the passage of water and dust from the outside from coming into said attic when said strip of upright synthetic fibres is situated in abutment with said adjacent plate.
Claim 2
Dependent Claim
174 words
A corrugated interlocking tile roofing plate having opposite side surfaces and comprising proofing strip means on at least one of said surfaces and extending thereacross, for providing a substantially water impervious barrier while generally providing an air and humidity permiable passageway, said plate being adapted to be arranged on a roof partly overlapping and partly being overlapped by adjacent roofing plates, said roof defining an attic thereunder, and said proofing strip means including a strip of upright synthetic fibres located on said plate on regions thereof which are overlapped by adjacent plates, to provide a fibrous barrier between said side surface of said roofing plate and the opposite side surface of one of said adjacent roofing plates which permits the passage of air in and out of said attic and further permits the passage of humidity to escape to outside said loft but substantially blocks the passage of water and dust from the outside from coming into said attic when said strip of upright synthetic fibres is situated in abutment with said adjacent plate.

A roofing plate according to claim 1, including a first proofing strip being arranged on an upper side surface of said plate at its uppermost horizontal edge thereof, and a second proofing strip being arranged on a lower side surface of said plate at its lowermost horizontal edge thereof.
Claim 14
Dependent Claim
157 words
