The invention relates to a roof window comprising a frame and a laminated vacuum insulated glass (laminated VIG) unit fixed in said frame, the laminated VIG unit comprising: a first glass sheet and a second glass sheet, wherein the first and second glass sheets are separated by an evacuated gap, and wherein a plurality of support structures are distributed inside the evacuated gap between the first and second glass sheets, a lamination layer arranged between the first glass sheet and a further sheet, said lamination layer is bonding to an outer major surface of the first glass sheet facing the evacuated gap, wherein the lamination layer comprises at least a first layer and a second layer of a polymer material, wherein, when the roof window is exposed to impacts; the fluctuation in decibel (dB) over a range of 1000 Hz in the interval from 20 Hz to 13000 Hz will not exceed 10 dB.

A vibration and sound deadening treatment applied to the exterior of downspouts or other gutter pieces which quiets any sound generated when water or other weather contacts the downspout. When placed on the exterior of the downspout, especially near turns in the spout, sound generated by rain and water moving through the downspout is dampened by reducing or removing completely the vibrations generated by the rain and water. This prevents the need to place anything inside of the downspout that may wind up clogging the spout and drain.

Provided herein is technology relating to measuring and recording weather phenomena and particularly, but not exclusively, to apparatuses, methods, kits, and systems for measuring hydrometeor impacts, e.g., hail impacts.

A downspout cord or the like conveyance device and method, comprised of a sufficiently heavy and at least partially rolling mass, preferably that rotates around an axle which is connected to a harness and to which a cord or the like may be attached and pulled down a bent downspout largely by the force of gravity.

A device for reducing and/or eliminating water noise. A screen made of waterproof material has small holes distributed across its entire surface, to reduce the size of water droplets exiting the screen to less than 5 mm.

A modular anchor has a metal plate having a pattern of holes around a periphery, the forming a boundary of a central inner area, a metal bracket having a raised central portion and parallel wings having upper and lower surfaces in parallel horizontal planes, with the bracket joined to the metal plate at a central location within the hole pattern, the wings and the metal plate coated with a material to facilitate heat welding to membrane; and a transition membrane positioned on the metal plate with the raised portion of the bracket extending upward through an opening in the transition membrane, and with the transition membrane heat welded to the upper surfaces of the wings of the bracket and to the metal plate everywhere within the central inner area, leaving the pattern of holes exposed.

A method for mounting a fixture on a membrane-covered roof involves a bracket with wings coated on upper surfaces with a material rendering the wings heat weldable to roofing membrane. The bracket is placed on the roof membrane, and a transition membrane with a cutout for a raised portion of the bracket is placed over the bracket and heat welded to both the upper wing surfaces of the bracket and to the roof membrane.
