Glass that counts as wood
According to the wiki, it does not appear to give crop plots any greenhouse effect. Its appeal lies elsewhere: it is transparent and is treated as a wooden structure, and the wiki rates it a better pick than the greenhouse structures for a window or a clearer view of the landscape.
As a wooden structure it cannot be harmed by bare hands, stone weapons or ranged attacks that do not explode. Many aggressive creatures cannot damage it either; the wiki names the 
Titanoboa, 
Sabertooth, 
Direwolf, 
Raptor, 
Terror Bird, 
Kaprosuchus, 
Thylacoleo and 
Pulmonoscorpius among them.
