| Cast Windows |
|
 |
| Cast shielded
windows are constructed with integral mesh or conductive
coated surface. Cast windows tend to be slightly
lower in cost than Laminated windows but are not
as optically efficient |
|
| Laminated Windows |
|
|
Laminated windows
give a clearer image than cast and are constructed,
as the name suggests, from layers of polycarbonate
or similar.
The layers can be milled to create 'steps'
that can be fitted into pre made slots.
