Aluminum Coating: Applied to all interior Velux Blinds, on the reverse side of the blind (the side of the cloth or slat closest to the pane) to reduce the heat gain in the room.
Argon Gas: A colorless, odorless, inert gaseous element constituting approximately 1% of the earth's atmosphere, used in electric lamps, fluorescent tubes, and insulated glass window panes. Because Argon is denser than air, it is a good insulator and is used in all Velux skylights and roof windows.
Awning: An exterior blind installed on the roof side of the skylight and the best possible way to minimize heat gain through a skylight/roof window.
ASTM: American Society for Testing and Materials - a voluntary organization concerned with development of consensus standards, testing procedures and specifications.
Blinds: Sunscreening accessories such as venetian blinds, pleated shades, LightBLock shades, and Awning Blinds, designed to limit or block out light.
Cladding: Cladding is an exterior aluminum armor that offers protection from the elements and offers a streamlined appearance.
Combi-Flashing: Refers to a flashing system that combines multiple skylights for almost unlimited design possibilities.
Condensation: A chemical reaction that causes water droplets to form when warm, moist air contacts a cold surface. All Velux skylights are designed to minimize the chance of condensation by protecting the interior glass from cold, outside air with a special Low-E coating and argon gas that is vacuum sealed in the space between the interior and exterior panes of glass.
Controls: The way you operate the venting skylight or blind. Can be manual or electric.

Both units are filled with Argon gas and double coated with an exclusive Low-E coating.
Head Flashing Piece: The flashing component that interlocks with the skylight top cover and is placed under the roofing felt to insure proper water drainage.
Header Framing: Structural lumber that ties two or more rafters together at the top of the skylight roof opening to form bracing for the surrounding roof structure.
Heatblock: Exterior awning that conrols the heat coming through the skylight and reduces heat ga in in the room.
Identification Tag: All Velux skylights and roof windows will have a label which explains the size for the skylight. All skylights and roof windows with a one to three digit number will be in standard dimensions, and this number must be used for ordering blinds (no additional measurements are required).
Impact Glass: The glass is very resistant to penetration from flying debris. Velux impact glass meets the requirements for wind-borne debris protection of the IBC (International Building Code Commercial), the IRC (International Residential Code) and the Florida Building Code 2001, with exception of Dade County Protocols.
Interior Blinds: Blinds installed on the room side for the skylight (in the sash if venting or on the frame).
Laminated Glass: Made up of bonded layers. Two panes of heat strengthened glass bonded together around a vinyl inner layer that holds the glass together if it gets broken.
Light Shaft: Flat ceilings with an attic space between the ceiling and the roofing require a light shaft to deliver the light and view from the roofline into the interior opening.
LightBlock: Interior room darkening shade that can convert day to night. It will not be possible to find your way in the room, without light from sources other than the skylight.
LoE3: LoE3 is a metallic coating that is chemically bonded to the glass and protects against heat gain and fading rays. Now with triple coating.
National Fenestration Council (NFRC): The NFRC rates windows, doors, and skylights on their overall energy performance. Its tests are independent and prescribe uniform testing parameters, which gives consumers a way to accurately compare products.
Outside Frame: The outside frame dimension refers to the outer-most measurement of the wooden frame on Velux skylights and roof windows.
Pan Flashed: Pan-flashed is referring to a type of skylight with insulated glass lens, wood frame and protective cladding, combined with factory installed metal pan flashing with welded corners and painted that mounts directly to the roof deck and requires roofing sealant.
Pitch: The angle of a roof. The angle which the roof surface makes with a horizontal plane. It is a ration of rise to the span.
Rafter: The supporting frame member immediately beneath the deck, sloping from the ridge to the wall plate.
Remote: Infrared remote control which via the electrical control will be able to operate the electric venting skylight or blind.
Roof Window: Roof windows are designed to be installed within reach, such as attics, bonus rooms, and loft areas. Their sashes will rotate around, allowing the outside glass to be cleaned from inside the house.
Rough Opening: The actual hole that is cut in the roof decking to install a roof window or skylight.
Sash: A frame in which the glass panes of a window or door are set. The part of a ventilating roof window or skylight that opens out from the frame.
Self Flashing: Self-flashing units do not require curbs or additional flashing components to create a watertight seal.
Shades: Pleated shades, roller shades and LightBLock shades offer options for room darkening and light filtering.
Shaft: The section of the ceiling that projects a ray or beam of light.
Sill Flashing Piece: The sill flashing component is at the bottom of the skylight and is placed between the underglass rubber gasket and bottom frame section to the provide a watertight seal.
Sill Framing: Structural lumber that ties two or more rafters together at the bottom of the skylight roof opening to form bracing for the surrounding roof structure.
Step Flashing: Step flashing is a system that interweaves 'L' shaped flashing pieces with the roofing material going up the sides of our units to provide a watertight seal. No sealants that can break down over time are required.
Stick Built: A term used to describe the conventional framing technique of building the roof structure one piece of lumber at a time. The opposite approach involves pre-engineered and factory-built truss systems that form a roof structure when put into place on the job site.
Sun Tunnel: A tubular daylighting device that captures daylight at the roof and carries it through a tubular shaft to deliver light into your home. Can be either rigid or flexible.
Tempered Glass: Glass having an additional degree of hardness that shatters into small pieces rather than into large shards of glass when broken.
Truss: A rigid framework designed to support a structure.
Underlayment: Something under laid, as paper under shingles,. Either ice and water shield or felt paper are used to wrap a skylight for insulation.
UV: Ultraviolet light that fades the interior. Velux glazing in the skylight and blinds are efficient solutions to this issue.
Venting Skylight: A venting skylight is a unit that is hinged at the top and opens mechanically at the bottom to provide fresh air and temperature control.
Wrapping a Skylight: Roofing underlayment or roofing felt are wrapped around the skylight frame or curb to dramatically reduce the chance of condensation and provide added protection from extreme weather.
Iossi offers both Deck mounted and Curb mounted skylights. A Curb mounted skylight is mounted on a curb style frame which is raised off the roof sheathing. A Deck skylight sits on the sheathing.
Skylights with pre-finished wood frames need to be inspected annually. The finish that is applied to the wood surface is not considered a permanent coating. As with any finished surface it is subject to peeling, cracking or fading and will need to be refinished /re-painted periodically.
Unfinished Wood Frames need to be painted, stained, or varnished within 6 months of installation. Failure to finish bare wood can result in discolored wood, deterioration of the wood frame/sash and possibly lead to bowing and splitting of the wood.:
Painting over Plastic (ABS or PVC) frames and sashes is not recommended.
Exterior Solar Panels:
Acrylic plastic has a highly polished lustrous surface and will retain its appearance for many years if given proper care.
Wash with mild soap or detergent and lukewarm water solution, using a clean soft cloth or cellulose sponge and as much liquid as possible. Household ammonia in water, in concentrations recommended for general cleaning is also excellent. Rinse well and remove remaining excess water with a damp soft cloth, chamois or moist cellulose sponge.
To protect the surface and maintain luster, apply a think, even coat of a good grade of automobile paste wax (NOT a cleaner wax combination) with a soft clean cloth. Buff lightly with a clean cotton flannel or jersey cloth. After polishing, wipe with a clean damp cloth to ground any electro-static charges which may attract dust particles.
Fine scratches may be removed or minimized by gently applying a t hin, even coat of a good grade of automobile cleaner-polish with a clean soft cloth. Cleaner-polish has a very mild abrasive action and its wax content tends to fill fine scratches and make them less visible. Test the polish on an unobtrusive portion of the plastic and follow the manufacturer's directions for use.
Polycarbonate plastic has a highly polished lustrous surface and will retain its appearance for many years if given proper care.
When first installed, glazing compound, mortar, primer, paint, sealant, adhesive tape, labels, stickers, etc., can be easily removed by carefully applying naphtha, kerosene, or petroleum spirits with a clean soft cloth, followed by a thorough soap and water cleaning. CAUTION: use these materials carefully because they are flammable! Avoid sparks, open flame, or other ignition sources. Do not smoke while using them.
Wash with mild soap or detergent and lukewarm water solution, using a soft clean cloth or cellulose sponge. Rinse well and remove remaining excess water with a damp soft cloth, chamois or moist cellulose sponge.
