Our core focus across Spain is technical consulting and the distribution of high-performance natural insulation and off-grid energy systems. This is where we stand apart: our consulting is driven entirely by field experience, not theory. We specialise in supplying natural, vapour-permeable insulation—such as Steico, Diasen, and hemp—alongside commercial-grade Victron off-grid power systems. We only sell products that we actively use, install, and trust, ensuring every sale and every piece of advice is backed by years of direct installation experience to give you practical, proven solutions rather than just a sales pitch.

To maintain this hands-on expertise, we take on a select number of high-end, high-performance restorations of historic ruins here in Western Asturias. We partner with clients who appreciate doing things properly and understand that real quality takes time. Working in remote locations means we have to be self-reliant. When managing these projects, we handle the groundwork, structural rebuilds, breathable insulation, lime plastering, underfloor heating, air circulation, plumbing, and electrical work ourselves. We also design and fit the complete off-grid solar arrays and heavy-duty battery storage we distribute, pair them with satellite internet, bring our mobile sawmill on-site for custom timber milling, and manage land rehabilitation.

Cádiz and across Andalucía, we work closely with BioReforma S.L. This partnership means projects in the south receive the same rigorous standard of natural insulation installation, run by a regional specialist whose experience we trust completely.

Where is your project?

We'll determine your CTE climate zone and required U-value targets automatically.

Region (Comunidad Autónoma)

City / Province

What are you insulating?

Select the wall or structure type. This determines which CTE U-value limit applies.

Choose your insulation

ECS stocks natural, vapour-permeable materials from Steico, von Hanf, Rockwool and Diasen.

Add a finish or substrate layer (optional)

A cork render, clay plaster or lime coat adds thermal mass and controls moisture. Recommended for historic buildings.
