As environmental concerns and global demand for energy continue to surge, both individuals and businesses are trying to find ways to minimize their ecological footprints. Architects, builders and homeowners are increasingly turning to innovative and sustainable materials for renovations and new construction projects. This is where insulation cork comes into play.
Insulation cork, commonly referred to as semi-rigid insulation cork sheets or expanded cork board, is one of the most environmentally friendly building materials available. This remarkable building material is derived from the bark of the cork oak tree (Quercus suber) with no harm to the tree. In fact, the tree can be harvested time and time again for 200 or so years. The unique cellular structure and inherent thermal properties of cork make it an attractive choice for sustainable construction. In this post, we’ll explore what insulation cork is, why it's gaining prominence, and how it contributes to eco-friendly building practices.

What is Insulation Cork?
Expanded insulation cork is derived from natural cork granules, a by-product of the stopper industry. The cork granules are steam-heated causing them to expand and release suberin, a natural binder. No additives, chemicals or binders are added. The cork granules and suberin are pressed into blocks and cut to the desired dimensions.
What are the Benefits of Using Insulation Cork in Construction Projects?
The natural characteristics of cork all come into play with this amazing 100% natural product:
Excellent thermal insulation
Excellent acoustic & anti-vibration insulation
Light-weight yet durable
Permeability to water vapor
Stability with temperature extremes
Where Can Insulation Cork be Used?
Cork has been used as an insulation material for centuries, particularly for cold storage. In construction these semi-rigid expanded cork boards can be used on:
Interior & Exterior Walls, Cladding
Roofs & Ceilings
Cavity Walls
Slabs & Flooring

Semi-rigid insulation cork sheets are designed for insulation purposes however their multifunctional nature along with their thickness allows them to serve as wall and ceiling tiles and bulletin boards as well.
Insulation Cork & Eco-Friendly Building Practices
Using cork in our buildings, helps insulate our interior spaces reducing our energy consumption. The use of cork insulation helps keep the cold out in winters and the heat out in summers.
Totally Sustainable and Renewable Material
100% natural cork
Durable yet recyclable
C02 sink (carbon negative / climate positive)
Cork from sustainable forestry operations
By-product/waste from the cork stopper industry
Given its numerous qualities and the indisputable fact that cork is one of the most amazing natural materials out there, it is no wonder homeowners and builders are increasingly turning to cork for their renovation and construction needs.
