We offer top options from solid ABS plastic to perforated aluminum. The ABS is great for your reptiles that need more humidity. Ventilation holes can be added as desired. The perforated aluminum is ideal for maximum ventilation and allows the use of heat lamps and other lighting.  Below are two close-up pictures to compare.
