=== Glass ===

Glass is used in ''Portal 2'' as well as ''Portal''. It blocks bullets from [[turrets]] but allows a [[Thermal Discouragement Beam]] to pass through it. Glass is transparent and [[gels]] do not stick to it.

=== Grates ===

Grates, like glass, allow Thermal Discouragement Beams to pass through. However, they also allow bullets from [[Turrets]] to pass through. Gels flow through grates but do not stick to them.

Portal surfaces are white and conduct [[portals]]. According to [[Cave Johnson]] in ''Portal 2'', good portal conductors are made of concrete and moon rock dust. They are controlled by [[panels]]. Gels stick to portal surfaces and do not interfere with their ability to conduct portals.

~~=== Regular Wall ===~~

Like portal surfaces, walls are controlled by [[panels]]. It is possible that the wall might be painted to stop it from conducting portals, as in one test chamber things peel off the walls and the wall becomes a portal surface. [[Gels]] stick to walls.
