Hello: WE have a green house above that is our patio with metal roofing which unfortunately is blocking all available sun light.WE are planning to change the roofing of the patio to glass.They are recommending a little tint in the glass to protect from uv in order to protect the carpet etc from uv.

What kind of glass would be most suitable that would give sun and natural light to the green house below ( the green house has a glass roofing, but the patio above has metal and is blocking most of available sun.We want to protect the patio from uv, but we also need to give the most light to the green house.Any ideas ? Thanks so much
