Outside measurement of frame width & height.
Opening in bulkhead, often referred to as “plate-cut”
Section of frame that protrudes through rough opening.
Is the opening that you can physically pass through when the door/hatch is in full open position.
Individually operated dogs (cleats) used to secure door/hatch for weathertight & watertight application.
Variations of Interior & Exterior options available.
Lever or wheel used to operate multiple dogs with a single operation.
Interior operated only, can be individually operated dog or quick-acting.
Main frame installed into bulkhead that the door/hatch insert will be fitted to & seal to.
Door/hatch panel mounted to the frame via hinges or can be supplied as lift-out.
Door/hatch main frame is installed and secured to bulkhead via mechanical fasteners.
Door/hatch main frame is installed and secured to bulkhead via welding method.
Door/hatch main frame is installed and secured to bulkhead via interior clamp ring.
Hinge doors refer to direction of the door swing when viewed from outside looking at key cylinder side.
Insert swings outward, Left-hand (LH) hinge on left or right-hand (RH) hinge on right.
Sliding doors refer to direction of slide (again viewed from exterior), left-hand sliding (LHS), door slides left or right-hand sliding (RHS), door slides right.
Lockset assembly includes – lever handles, lock case, keyed exterior cylinder, interior thumb-turn & supplied with roses or escutcheons plate.
Available in satin or chrome polished.
Includes – lock case, keyed exterior cylinder, interior thumb-turn & round roses or rectangular escutcheons plates.
Available finishes are satin or polished chrome.
Includes – lever handles, passage lock case & round roses or rectangular escutcheons plates.
Available finishes are satin or polished chrome.
Designed to withstand and prevent the ingress of water exterior. Typically used above the waterline.
Will withstand water to a defined head pressure from exterior seating &/or both exterior seating & interior unseating pressures.
Typically used below the waterline locations such as engine rooms, watertight boundaries & transoms.
Chromic Acid anodizing is a metal coating process used when the application calls for a thin coating and a high level of corrosion resistance. MIL-A-8625F type I
Proven electrochemical process that transforms a plain metal surface into an engaging exterior that provides both advanced corrosion-resistance and durability. MIL-A-8625 Type II
Mill finish is the as extruded appearance of aluminum, no external mechanical or chemical finishing to the surface of the metal.
Buffed with an orbital sander, no chemical finishing to the surface of the metal.
Electrostatically charged colored powder that is applied to the metal and then baked on to provide a protective hard-wearing coating.
Wet paint system in a wide range of colors and brands.
Sheet/plate glass, often called “float glass” that has not been heat-strengthened or tempered.
Like tempering, with a slower cooling process. Heat-strengthened glass is approximately twice as strong as annealed glass but breaks into shards.
Heat treated safety glass, breaks into small 1/8” crumbles.
Chemically treated plate glass which is agitated to remove all imperfection in glass surfaces meeting or exceeding strengths of tempered glass.
Two or more pieces of glass bonded together using an .030 or .060 inner layer of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA).
Considered to be safety glass due to strength of bonded panel and the fact the panes remain stuck together even after damage. Insulation properties & sound attenuation properties are much greater than standard tempered glass and can reduce UV transmission along with adding tints.
Tempered laminated glass with a built-in electrical element to create heat transfer across the glass to eliminate fogging or icing.
2 or more panes of heat reflective glass separated by an air gap using a desiccant spacer to reduce heat and noise transfer.
Is achieved using a wet belt sander and removes the sharpness of the glass edges. Primarily applied to ensure the glass is safe to handle.
CNC machine removes all sharp edges and leaving a diamond smooth unpolished edge with a satin, white appearance.
After flat grinding an additional process is completed on our CNC machine.
All edges are polished producing a smooth, gloss finish similar to the glass surface, utilised on glass products where edges are exposed.
Used when discussing tint, VLT is the percentage of the light that passes through glass. The higher the number the more light is passing though and vise versa. Example: VLT 9% gray, will have a dark gray tint only allowing 9% visible light transmission.
An internal ring that pinches the exterior bulkhead and holds the window in place along with providing an interior beauty trim.
Options are Z-trim, Flat bar ring or L-trim
Window frame is installed and secured to bulkhead via mechanical fasteners.
An angled corner formed by cutting and welding each leg of extrusion on a window.
A rounded corner formed when the window extrusion is bent in our bending machine.
Used between panes of glass in a window to add strength.
Used particularly in oversized windows.
Is the outside measurement of main frame.
The projection of the frame that will fit into the hole or opening.
Viewing area when looking through window frame. Or glass view is the glass area or area of the window. The area you will effectively be looking through.
Describes the configuration of sliding pane. The “X” pane is the active panel, “O” pane is the inactive/fixed pane. Also described as active or inactive panes.
Raised leg on lower frame edge to prevent ingress of water in harsh environments.
A damn built to the lower frame to prevent the ingress of water where a window will be used in particularly harsh environments.
A fixed/vent window with a hinged opening on bottom section.
A fixed/vent window with a hinged opening on top section
Opening window with hinges across top where entire vent portion hinges open.
A sliding window where the top half of the window is the active (X) panel and the bottom half is the inactive (O) panel. Opening from top to bottom.
A sliding window where the entire pane slides vertically down to open.
A sliding window where the rear/aft pane is the active (X) panel.
