Types of Cork Underlayment
Cork underlayment is a popular choice for soundproofing and insulating floors. It is made from the bark of the cork oak tree, which is harvested without harming the tree. Cork underlayment comes in different types, each with its own unique characteristics and benefits. In this article, we will explore the different types of cork underlayment and their uses.
Standard Cork Underlayment
The most common type of cork underlayment is the standard cork underlayment. It is made from natural cork and is typically available in rolls or sheets. Standard cork underlayment is known for its excellent sound absorption properties, making it ideal for reducing noise transmission between floors in buildings. It also provides thermal insulation, helping to keep floors warm in winter and cool in summer. Additionally, standard cork underlayment is resistant to moisture and mold, making it suitable for use in areas prone to water exposure, such as basements and bathrooms. It can be easily installed by rolling or gluing it onto the subfloor, providing a smooth and level surface for the flooring.
Agglomerated Cork Underlayment
Agglomerated cork underlayment is made from small pieces of cork that are compressed together using heat and pressure. This type of cork underlayment is more cost-effective compared to standard cork underlayment. Agglomerated cork underlayment has similar sound absorption and thermal insulation properties as standard cork underlayment, but it is not as durable. It is suitable for use in areas with light to medium foot traffic, such as bedrooms and living rooms. Agglomerated cork underlayment is available in rolls or sheets and can be easily installed using adhesive.
Expanded Cork Underlayment
Expanded cork underlayment is made from cork granules that are expanded using steam and heat. This process creates a lightweight and highly resilient material. Expanded cork underlayment has excellent sound absorption properties and can effectively reduce impact noise, such as footsteps and furniture movement. It also provides thermal insulation and is resistant to moisture and mold. Expanded cork underlayment is suitable for use in residential and commercial buildings, particularly in areas where noise reduction is a priority, such as apartments, offices, and recording studios. It is available in sheets and can be easily installed using adhesive.
Composite Cork Underlayment
Composite cork underlayment is made by combining cork granules with other materials, such as rubber or foam. This type of cork underlayment provides enhanced sound absorption and insulation properties compared to standard cork underlayment. It is also more resistant to compression, making it suitable for use in areas with heavy foot traffic, such as hallways and commercial spaces. Composite cork underlayment is available in rolls or sheets and can be easily installed using adhesive or the floating floor method.
Cork Floating Floors
Cork floating floors are a type of cork underlayment that comes in interlocking planks or tiles. This type of cork underlayment is designed to be used as the primary flooring material. Cork floating floors provide excellent sound absorption and insulation properties, as well as a comfortable and resilient surface to walk on. They are available in various designs and finishes, allowing for a wide range of decorative options. Cork floating floors are suitable for use in residential and commercial spaces and can be easily installed without the need for adhesive or nails.
