Why We Chose This Range
“We have specialized in aluminium frames since 2012 because they represent the best value-to-longevity ratio for the average UK gardener. While timber has its aesthetic charm, a high-quality aluminium frame like those in our Elite or Vitavia ranges will literally outlast the gardener if the base is prepared correctly. We specifically curate models with built-in guttering and box-section glazing bars; in our experience, these small engineering details are what prevent frame-twist during 70mph winter gales.”
— Matt, Founder of Greenhouse StoresChoosing Your Aluminium Greenhouse
Size selection depends on your available space and growing ambitions. Popular starter sizes include 6x4ft models (perfect for balconies), while serious gardeners prefer 8x6ft or larger configurations. Our 8x6 greenhouses strike an ideal balance between internal space and overall garden footprint.
💡 Glazing choice significantly impacts performance, wind resistance, and safety. For the unpredictable British climate, we strongly recommend 3mm Toughened Safety Glass. It offers the best combination of 100% clarity, excellent safety, and superior wind resistance due to its heavy, rigid long-pane design. While twin-wall polycarbonate offers better insulation, its lightweight nature makes it unsuitable for open or windy locations. Small polycarbonate greenhouses, such as lean-to models, start from just £175.
🔧 Matt's Installation Tip: The "Square" Foundation
Aluminium frames are incredibly strong but they have zero 'flex' compared to wood. If your base is even 5mm out of square, the door will bind and the glass won't sit flush. I always tell customers: spend 80% of your time on the base and 20% on the frame.
For aluminium models, we highly recommend a level concrete perimeter or paving slabs. If you are using the integral base kit, ensure the ground anchors are concreted in; don't just 'spike' them into soft soil, or a storm will lift the entire structure. Read our full base guide here.
Key Features to Consider
Frame Construction
- Standard Aluminium Frames: High-quality standard frames offering excellent durability.
- Heavy-Duty Box-Section Frames: Premium models like the Elite Titan and Janssens ranges use robust box-section profiles.
- Powder-coated finish: Available in 10 colours including forest green and anthracite grey.
- Corner bracing: Reinforced joints prevent frame flexing (standard on high-spec models).
Glazing Options
- 3mm Horticultural Glass: The traditional, lowest-cost option.
- 3mm Toughened Safety Glass: Our top recommendation. Rigid, heavy panes provide the most wind-resistant glazing choice.
- Polycarbonate: Shatterproof and lightweight. Best for polycarbonate greenhouses in sheltered family gardens.
Frequently Asked Questions
-
Is an aluminium greenhouse better than a wooden one?
Aluminium is generally superior for those seeking zero maintenance. It won't rot, warp, or require annual staining. However, wood provides better natural insulation. For most UK gardens, aluminium's durability and slim profiles (which let in more light) make it the more practical choice.
-
Does aluminium rust?
No. Aluminium naturally forms a protective oxide layer that prevents rust. Our powder-coated models add an extra layer of protection, making them ideal for coastal areas where salt spray can be an issue.
-
Which glazing should I choose for an aluminium frame?
Choose Toughened Glass for wind resistance and safety. Polycarbonate is best if you have children or pets as it is shatterproof, though it is less suitable for high-wind areas.
-
Can I install an aluminium greenhouse myself?
Most models can be self-assembled in 6-12 hours for two people. However, our professional installation service ensures perfect construction. A firm, level base must be completed before our installers arrive.
