Mineral Wool

Versatile, Safe and Effective – Used Across All Our Systems

‍

At EnergyEase, we rely on high-performance mineral wool as the core material in many of our insulation solutions — from blown-in cavity wall insulation to attic rolls and roof finishes. Why? Because mineral wool offers the best combination of thermal comfort, fire safety, and acoustic control — and adapts perfectly to Portugal’s diverse housing types.

We select different types of mineral wool depending on the application, always aiming for maximum efficiency and comfort with minimal environmental impact.

🌬️ 1. Blown-in Mineral Wool – For Cavity Walls & Hard-to-Reach Spaces

Product used: Knauf Insulation Supafil Cavity 033

For homes with double masonry walls (paredes duplas) or inaccessible attics, we use loose-fill mineral wool that is mechanically blown into wall cavities or hard-to-reach spaces.

Key benefits:

• ✅ Fills the entire cavity with no gaps
  
• ✅ Non-combustible (Euroklasse A1 – highest fire rating)
  
• ✅ Moisture-resistant and breathable — no mould, no rot
  
• ✅ Improves both thermal and acoustic performance
  
• ✅ Made from up to 80% recycled glass
  
• ✅ Certified for indoor air quality (Eurofins Gold + DECLARE label)
  
  

This type of mineral wool is lightweight, durable and settles less than 1%, ensuring your insulation stays effective for decades.

👉 Perfect for: cavity walls, closed attics, false ceilings

🪵 2. Mineral Wool Rolls – For Accessible Attics and Roofs

Product used: Volcalis Easy Rolo Alumínio Kraft

When space allows, especially in walkable attics or sloped roof renovations, we use roll-based mineral wool. These rolls come with a built-in aluminium kraft vapor barrier for extra protection against humidity and heat transfer.

Why choose it:

• 🌡️ Excellent thermal insulation values
  
• 🔇 Great for soundproofing
  
• 💧 Ideal for humid zones (e.g. coastal regions)
  
• 🔥 Non-combustible and thermally stable
  
• ✅ Produced from natural and recyclable raw materials
  
• 🌱 Can be reused or recycled through controlled systems
  
• 🧼 Easy and safe to install with minimal irritation
  
  

👉 Perfect for: attic floors, pitched roofs, under-tile insulation.

🔒 Fire Safety You Can Trust

All mineral wool products used by EnergyEase meet the highest European fire safety standards (A1 or B-s1,d0), meaning:

• They do not burn or spread flames
  
• They do not release toxic smoke
  
• They provide an extra layer of protection for your home and family

‍

This makes mineral wool ideal not just for energy efficiency, but also for peace of mind — especially in attics and wall systems near electrical wiring or heat sources.
