Floor Insulation

What Is Floor Insulation?

Floor insulation involves installing insulation material beneath the floor of your home. It is an effective way to reduce heat loss and improve your home’s energy efficiency. By helping to maintain a more consistent indoor temperature, floor insulation reduces the amount of energy required to heat your home during winter and keep it cool during summer. It also minimises draughts and creates a more comfortable living environment. There are several ways to insulate a floor, depending on the type of floor and the accessibility of the space beneath it, such as insulating the crawl space or installing insulation above an existing floor.

Benefits of Floor Insulation

• Reduces heat loss through the floor, making your home more energy-efficient.
• Lowers your energy bills by reducing the amount of energy needed to heat your home.
• Creates warmer floors that are especially noticeable during the colder months.
• Helps prevent cold draughts entering your home through the floor.
• Contributes to lower CO₂ emissions, benefiting the environment.
• Helps control moisture in crawl spaces, reducing the risk of damp, mould and timber rot.
• Creates a healthier indoor environment through better moisture control and improved air quality.
• Provides a return on your investment through energy savings, depending on your property and the insulation system chosen.

Floor Insulation Materials

There are several ways to insulate your floor, each offering its own unique characteristics, benefits and applications. The most suitable solution depends on factors such as the type of floor, whether your property has a crawl space, your available budget and the level of insulation you want to achieve. Whether you choose PUR spray foam, glass wool or bio-based insulation, each solution is designed to reduce heat loss and improve comfort within your home.

• PUR Spray Foam (Polyurethane Foam) is a liquid foam that expands to create a seamless insulation layer. It is suitable for both concrete and timber floors.
• Crawl Space Insulation (insulation beads or shells) consists of insulation material spread across the floor of the crawl space to reduce moisture and minimise heat loss.
• HR Bio-Based PUR Spray Foam is a more sustainable alternative to traditional PUR foam, made from bio-based raw materials. It is ideal for environmentally conscious renovation projects.

Floor Insulation Costs

The cost of floor insulation depends on the type of floor and the space beneath it. For crawl space insulation, the price largely depends on the insulation material used and how accessible the crawl space is. In many municipalities and regions, grant schemes are available for home insulation, helping to reduce the overall cost of the installation.

Floor Insulation Grants

Several grants and financial support schemes are available in the Netherlands to help reduce the cost of floor insulation. These include national grants provided by the Dutch government, as well as local schemes offered by municipalities and provinces. Pluimers Insulation can help you understand which grants may be available for your project.

• ISDE – Sustainable Energy and Energy Saving Investment Grant (ISDE)
  The ISDE is the main national grant scheme available for improving the energy efficiency of existing homes, including floor insulation.
• Local municipal and provincial grants
  In addition to the national ISDE grant, some municipalities and provinces offer their own financial support for home insulation, including floor insulation. The conditions, grant amounts and availability vary by location.
