Cover the house with polycarbonate structured sheets treated to resist ultraviolet wavelengths or tempered glass. It is much stronger than glass, but lighter in weight. It has good insulation properties. It has excellent light transmission. It is flame retardant.
Tempered glass is expensive.
It does though provide excellent light transmission for plant growth. It is also long lasting. Tempered glass is stronger than regular glass, however it may still break during hail storms. Fiberglass loses light transmission as it wears out and it becomes extremely flammable as it ages and fibers become exposed. Polyethylene is the least expensive covering material, but it tears and must be replaced every 1-3 years depending on the thickness of the poly used.
