Glazing

If you’re looking at purchasing a greenhouse from this range, then the next thing to consider after the frame colour is the glazing. Both options will create a versatile greenhouse and growing area for your crops, but they do have their advantages and disadvantages.

Toughened glass is, as the name suggests glass that has been tempered to increase its strength and impact resistance. It also has the added benefit, that if it were ever to be smashed, it would break into tiny pieces, rather than large shards, posing less of a threat to you and your family.

Secondly, there's polycarbonate, which isn’t as common as the other and is a fairly new concept when it comes to greenhouses, but offers a lot of advantages. At 6mm thick, the polycarbonate used within Blockley greenhouses has incredible strength and is classed as being ‘virtually unbreakable’ due to its high impact resistance. If ever smashed, it won’t break into dangerous shards - thus making it the safest option for when children are present.

This polycarbonate is also twin-walled, similar to double-glazing which has two walls and an air gap in between. The air gap allows hot air, warmed up by the sun to get trapped inside the glazing, and inside the greenhouse, letting your plants make the most of the Sun’s natural heat source for longer as it’s not as easily lost.

Buyers Tip: If buying a greenhouse online, just ensure that the retailer you choose sells genuine Halls branded glazing along with the frame, as some of the cheaper selling retailers only sell a Hall branded frame and bundle it with their own cheaper alternative glazing and accessories.
