Insulation with Eco Cork Board

Updated: Nov 11

Eco Friendly & Breathable Interior / Exterior Insulation

Providing natural and sustainable insulation (extracted from the cork-oak tree every 9 years), the cork used in the Cork Board system is a breathable material, free from any chemicals, synthetic resins and carcinogenic materials. This therefore contributes to a natural, healthy environment inside or outside of your home.

Cork board insulation is valued for its thermal and acoustic insulating properties. It provides a natural and environmentally friendly alternative to traditional insulation materials. Here are some key characteristics and benefits of cork board insulation:

Thermal Insulation:

Cork has natural thermal insulating properties, helping to regulate temperature and reduce heat transfer. It can be used to insulate walls, floors, and ceilings, contributing to energy efficiency in buildings.

Acoustic Insulation:

Cork is known for its sound-absorbing qualities, making it an effective material for reducing noise transmission. Cork board insulation can be used in walls and ceilings to improve acoustics by absorbing and dampening sound.

Renewable and Sustainable:

Cork is a renewable resource because the cork oak tree can be harvested multiple times throughout its life without harming the tree. The harvesting process involves stripping the outer bark, allowing the tree to regenerate.

Lightweight and Flexible:

Cork board insulation is lightweight and flexible, making it easy to handle and install. It can be cut to size with simple tools like utility knives or saws.

Natural Resistance to Mold and Mildew:

Cork has natural properties that make it resistant to mold, mildew, and pests. This can contribute to a healthier indoor environment.

Fire Resistance:

Cork has inherent fire-resistant properties, making it a safer option compared to some other insulation materials. It does not release toxic gases when exposed to flames.

Environmentally Friendly:

The production of cork board insulation has a lower environmental impact compared to many synthetic insulation materials. Cork harvesting promotes the health of cork oak forests and supports biodiversity.

Application method:

Applying cork board insulation to a wall can be a relatively straightforward process. Cork board is a natural and sustainable material that provides both thermal and acoustic insulation. Here's a general guide on how to apply cork board insulation to a wall.

1. To Preparation

Start by cleaning the wall surface to ensure it is free of dust, dirt, and any protruding objects. Repair any existing damage to the wall, such as holes or cracks.

2. Locate Studs

Use a stud finder to locate and mark the position of the wall studs. This is where you'll secure the cork board for better stability.

3. Measure and Cut

Measure the height and width of the wall, and mark these dimensions on the cork board sheets. Use a straight edge and a utility knife or fine-toothed saw to cut the cork board sheets to the appropriate size. Make sure to wear appropriate safety gear.

4. Apply Adhesive

Apply construction adhesive to the back of the cork board sheets. Be generous but not excessive, as excess adhesive can squeeze out from the edges.

5. Install Cork Board

Press the cork board sheets onto the wall, starting from one corner. Make sure to align the edges with adjacent sheets and the wall studs. Apply firm, even pressure to ensure good adhesion. You may use a roller to press the cork board firmly onto the wall.

6. Secure with Screws or Nails

Secure the cork board to the wall by driving screws or nails through the cork board and into the wall studs. Space the fasteners evenly along the edges and in the center of the sheets.

7. Trim Excess

If necessary, use a utility knife or saw to trim any excess cork board along the edges for a clean finish.

8. Fill Gaps

Fill any gaps between cork board sheets or around the edges with additional construction adhesive. Smooth the adhesive with a putty knife for a neat appearance.

9. Sand and Finish (Optional)

If you want a smoother finish or plan to paint the cork board, you can lightly sand the surface after the adhesive has dried. Apply the desired finish according to the manufacturer's recommendations.

10. Allow to Dry

Allow the adhesive to dry completely before moving or adding any additional finishes.

When using cork board insulation, it's important to follow the manufacturer's guidelines for installation. Cork board insulation is available in various forms, including sheets, rolls, or as part of composite materials. It can be used in residential and commercial buildings for both new construction and retrofitting existing structures to improve insulation and acoustic performance.
