Domes for access hatches or with ventilation
Domes are formed by heating the acryilc sheet and forming them using a vacuum.
The are robust, do not have any joins, and have the advantage of a wide range of
colours and tints to regulate how much light and heat enters the area below.
Access hatches are commonly used on office buildings where maintenance crews need
to access plant on the roof.
Installing an access hatch instead of a conventional staircase is a far cheaper option.
