Annealed glass – Annealed glass, the plain glass we’re all conversant in, is warmth treated and allowed to chill in a controlled approach in order that the internal stresses chill out slowly. Unfortunately, this means the glass may be very weak and liable to cracking or breaking when the temperature on both side of the glass adjustments rapidly. Annealed glass beneath pressure breaks into massive, jagged shards, making a hazard for anyone nearby. It’s the cheapest glass option and would work well for wall panels in a greenhouse where snow loads and high winds aren’t a concern.

Tempered glass – Tempered glass is a warmth-treated glass—the stresses in the glass are induced in a very particular technique to enhance the surface stress in relation to the inner stress. Tempered glass could be very clear, but as much as six times stronger than annealed glass and breaks into tiny, nearly sq. fragments that pose little risk to people. It’s a good selection for greenhouse roofs, partitions and doors resulting from its skill to deal with fluctuating temperatures, however shouldn’t be used on roofs where snow loads or high winds are a concern.


Laminated glass – Laminated glass is made of two or more sheets of glass bonded together utilizing a polyvinyl butyral (PVB) layer—it’s the identical glass your automotive’s windshield is made from. It’s extremely strong, like tempered glass, however in contrast to tempered glass, laminated glass doesn’t break. It may shatter, however the PVB layer holds the pieces together in order that they don’t pose a risk to anyone nearby.

A word about double-pane glass
Though it will appear that double-pane glass is the only way to go with a greenhouse, what works for homes isn’t all the time greatest for the new, humid conditions inside a greenhouse. The seals inside a typical double-pane window are typically assured for five to 10 years, however that assure is void in the event you install them in a greenhouse or indoor pool area. These areas accelerate the destruction of the seal, leading to premature failure and fogging. When it comes right down to it, you’re much better off insulating your glass greenhouse with bubble wrap than spending the money on most double-pane products. On the end of the day, you'll be able to always take the bubble wrap down, however a busted seal in a double-pane unit means the entire unit have to be replaced.
