Bioclimatic vs Classic Pergola — Complete Buying Guide 2026

Bioclimatic vs classic pergola — what differences really matter?

If you have a terrace and want to cover it, you will quickly encounter two main categories of pergolas: the bioclimatic pergola (with orientable aluminium louvres) and the classic pergola (with retractable fabric, manual or motorised). Both have clear advantages, but for different terraces.

What is a bioclimatic pergola?

A bioclimatic pergola has a roof made of extruded aluminium louvres that can rotate between 0° and 120°. When closed, the louvres form a watertight roof that channels rainwater through the profiles. When open, they ventilate the space below. The structure is permanent, in anodised or powder-coated aluminium.

Bioclimatic pergola advantages:

• Permanent roof — not weather-dependent for use
• Integrated water drainage — works in rain without fabric
• Fine light adjustment through louvre orientation
• Superior durability — rigid structure, no fabric wearing out

Bioclimatic pergola disadvantages:

• Significantly higher price than classic pergola (2–4× more expensive)
• More complex installation — requires solid foundations or anchors

What is a classic retractable fabric pergola?

A classic retractable fabric pergola (including Somfy models with Pergola RGS io motor) uses waterproof fabric stretched over an aluminium structure, which can be retracted manually or electrically.

Classic fabric pergola advantages:

• Accessible price compared to bioclimatic pergola
• Easy automation with Somfy motors (Pergola 50/60 RGS io)
• Excellent solar protection — UPF 50+ fabrics
• Complete retraction — terrace fully open when fabric is retracted

Frequently Asked Questions

What is the difference between a bioclimatic and a classic pergola?

A bioclimatic pergola has a roof of aluminium slats adjustable between 0° and 120°, with integrated water drainage — it works permanently, including in rain. A classic pergola uses a retractable fabric (manual or electric) that folds away when you want natural light.

Why is a bioclimatic pergola more expensive than a classic one?

A bioclimatic pergola costs 2-4 times more because it has a permanent aluminium structure, adjustable extruded slats, an integrated water-drainage system and more complex installation with foundations or solid anchors. In return it offers superior durability and all-weather use.

Does a bioclimatic pergola work in the rain?

Yes. When the aluminium slats are closed, they form a watertight roof that drains rainwater through the profiles, without fabric. When open, they ventilate the space below. This is the main advantage over a classic pergola, which depends on fabric for protection.

Which pergola should I choose for my terrace?

A bioclimatic pergola is ideal for permanent use, terraces used year-round and a larger budget. A classic pergola with retractable fabric (e.g. Somfy Pergola RGS io) suits an affordable budget and seasonally used terraces, offering flexible shade when needed.
