Glossary

Bolt-On

The closure is installed by bolting the frame to the cabin through bolt holes drilled in the mounting flange.

Butyl Tape

A sealant tape used between a window or door flange and the cabin of the boat to create an all weather seal.

 Clamp Ring

An interior ring that is screwed to the outside portion of the window frame to clamp the window to the shell plate. A clamp ring installation allows for an installation with no screws showing on the outside (and no screws penetrating the shell plate).

 Door Dogs

Lever handles that pull a door into its gasket creating a better seal.

Dutch Door

 Glazing

The material that is sealed into a frame. This could be any type of glass, Lexan, aluminum or steel.

 Laminated Glass

Regular glass bonded together with Poly Vinyl Butyral (PVB). If broken the PVB holds the glass together to reduce injury.

Lexan

Lightweight plastic that does not break as easily as glass. Available with a scratch resistant coating.

 Mitred corner

An angled corner formed by cutting and welding each leg of extrusion on a window.

 Radius Corner

A rounded corner formed when the window extrusion is bent in a bending machine.

 Safety Glass

There are two types of safety glass. Safety laminated and safety tempered.

Sealed Units

Two pieces of glass sealed together with an air space in between to create superior insullation.

 Tempered Glass

Glass that is heat treated and quenched to increase strength. It is approximately 5 times stronger than float glass. When tempered glass breaks it will shatter into many small and harmless pieces.

 Watertight

Impermeable to water.

Weathertight

Secure against wind and rain.

Weld-In

The closure is installed by welding the frame to the cabin.
