6mm — Standard Option
A strong, practical choice for most ACE installations. It provides good insulation, excellent light transmission and keeps the overall cost lower.
Choose 6mm if: you want the best balance of performance and price.
4mm or 6mm Polycarbonate?
Both options use the same heavy-duty Polyeco ACE steel structure. The main difference is insulation, rigidity and price.
6mm — Extra Insulation
The thicker 10mm polycarbonate provides improved insulation and greater rigidity, making it a good choice for customers who want better heat retention or plan to use the greenhouse more intensively through the colder months.
Choose 10mm if: insulation and extending the growing season are a higher priority.
6mm is suitable for most projects. Choose 10mm if you want the additional insulation and a more substantial cover.
Why Choose the ACE
Serious growing space. Built on a different scale.
Built on a Bigger Scale
A heavy-duty galvanised steel frame designed for year-round use in UK conditions.
Full-Height Side Walls
With approximately 2m straight side walls, you get much more usable space for shelving, tall crops, benches and comfortable movement inside the greenhouse.
Made for Serious Growing
The ACE is ideal for large gardens, schools, community projects, farms and commercial growers who need a greenhouse that can handle more ambitious growing.
Built to Order
Choose the width, length, 6mm or 10mm polycarbonate, doors, ventilation and other options to suit the way you plan to use the greenhouse.
More Space Changes What You Can Grow.
A bigger greenhouse does more than give you extra floor area.
It gives you room for proper growing beds, wide paths, benches, tall crops and larger harvests — without constantly working around the greenhouse itself.
The ACE is designed for people who have outgrown a standard domestic greenhouse and want a growing space they can genuinely work in.
Whether it is for a large garden, school, community project or commercial use, the idea is simple:
More room to grow. More room to work. More room to do it properly.
