There is no felted timber roof here. The roof is glazed with polycarbonate panels set into the metal frame, so daylight reaches your plants from above as well as through the sides.
An opening roof vent is included for temperature and humidity control, letting warm, moist air escape on bright days. The listing does not specify the exact roof profile, so check the retailer’s images if roof shape matters to you.
Dimensions
- Size: 6′ x 14′ (6×14 greenhouse)
- External dimensions: 1.85m x 4.26m
- Check measurements before ordering, especially if siting against a wall or fence
Construction
The metal frame is rust-resistant and low maintenance, which means less upkeep over the years. The panels slot into the frame securely, and a base frame is included to help you achieve a level, secure installation.
Polycarbonate panels are lightweight and shatter-resistant, and they hold heat better than glass while letting plenty of light through.
Treatment & Guarantee
With its metal frame and polycarbonate glazing, there is no timber to treat with preservative. The current listing does not state a guarantee period, so please confirm any warranty cover with the retailer before you buy.
Doors & Windows
The listing does not detail the door style for this model, so please check the retailer’s product page for the door configuration. Ventilation is provided by the opening roof vent, which lets you manage heat and humidity across the full length of the greenhouse.
Assembly Information
The Harmony 6×14 greenhouse arrives as a flat-pack kit with full assembly instructions, and all fixings and hardware are included. The listing suggests two people for the build, and a level, firm base is recommended before you start.
Delivery Information
Delivery is free to most UK mainland addresses. Some remote postcodes may incur a surcharge, so please check the final cost at checkout before you complete your order.
Optional Upgrades
No specific upgrade options are listed for this model. A base frame is already supplied, so the main thing to plan for is a solid foundation, such as a slabbed or timber base.
If you have less room to spare, the 6×12 Harmony in silver offers a slightly shorter footprint in the same finish.
Frequently Asked Questions
Is polycarbonate or glass better?
Polycarbonate is shatter-resistant, lighter and insulates better. Glass gives clearer visibility and higher light transmission.
Do I need a concrete base?
Not necessarily. A firm, level surface is recommended, and a slabbed or timber base works well. A base frame is also included.
Is delivery free?
Yes, delivery is free to most UK mainland addresses. Some remote postcodes may incur a surcharge, which is shown at checkout.
