Crawl Space Floor Insulation (Bodemisolatie).

Struggling with cold floors, dampness, or musty odors in your home? Bodemisolatie (crawl space floor insulation) from Thuiseco is the perfect solution to transform your living space. By insulating the crawl space beneath your home, we prevent moisture and cold air from seeping into your floors, creating a warmer, healthier, and more energy-efficient home. Save up to €200 per year* on energy bills and enjoy a cozier living environment with our advanced insulation solutions.

What Is Crawl Space Floor Insulation (Bodemisolatie)?

Crawl space floor insulation, or bodemisolatie, involves applying high-performance insulation materials directly to the ground of the crawl space—the shallow area under your home. Unlike floor insulation (vloerisolatie), which targets the underside of the floor, bodemisolatie is ideal for crawl spaces with limited height (less than 50 cm) or where access to the floor’s underside is tricky. Our solutions prevent heat loss, reduce moisture, and protect your home from mold and structural damage.

Costs of Floor Insulation

Before starting, a Thuiseco specialist will visit for a free consultation to assess your home and provide a tailored cost estimate. Costs vary based on factors like the floor’s surface area, crawl space accessibility, insulation material, and desired insulation thickness. Typically, the investment pays off quickly through energy savings, often within a few years.

Subsidies for Floor Insulation

In the Netherlands, various subsidies can help reduce the cost of floor insulation:

ISDE Subsidy: The Investment Subsidy for Sustainable Energy and Energy Conservation (ISDE) is a key national program supporting energy-efficient upgrades, including floor insulation. From 2022, you can receive up to €11 per square meter for floor insulation when combined with another insulation measure.
Local Incentives: Many municipalities and provinces offer additional subsidies for home insulation. Conditions and amounts vary, so contact Thuiseco for guidance on available options in your area.

Thuiseco’s Bodemisolatie Solutions for Low-Height Crawl Spaces

For crawl spaces under 50 cm, Thuiseco offers advanced insulation solutions designed for tight spaces, ensuring maximum warmth, moisture control, and energy efficiency. Our methods are tailored to outperform competitors in The Netherlands and beyond, delivering superior performance, safety, and sustainability with a focus on easy application in low-height environments.

HR EcoPearls: Our graphite-enhanced EPS pearls (Lambda 0.033 W/mK) are blown into the crawl space using a specialized machine, creating a thick, moisture-resistant layer (Rd-value ~3.5 m²K/W). These eco-friendly pearls reflect heat better than Pluimers’ HR-IsoPearl (Lambda 0.034–0.045 W/mK), offering superior insulation and energy savings in spaces under 50 cm.
Closed-Cell PUR Foam Spray: We spray high-performance closed-cell polyurethane foam (R-value ~6.2 per inch) across the crawl space floor, forming a seamless, airtight barrier. This method excels in low-height spaces, adhering to uneven surfaces, resisting moisture, and providing exceptional thermal resistance—perfect for maximum energy efficiency and durability.
Fire-Resistant Pearls: Our fire-retardant EPS pearls (BS476 Part 7 Class 1) are blown into tight crawl spaces, ensuring safety and insulation (Rd-value ~3.5 m²K/W). Like Pluimers’ HR-IsoPearl, these pearls are ideal for spaces under 50 cm, but with added fire protection for peace of mind.
BioBased PUR Foam Spray: A sustainable alternative, our biobased polyurethane foam (R-value ~6.2 per inch) is sprayed into low-height crawl spaces, creating an eco-friendly, airtight seal. Made from renewable materials, it offers the same high performance as traditional PUR foam while reducing environmental impact.
Eco Wool Chips: We spread sustainable eco wool chips, made from recycled cellulose or natural fibers (Lambda 0.045 W/mK), across the crawl space floor. This breathable, green solution is perfect for low-height spaces, providing excellent thermal insulation and moisture regulation with minimal environmental footprint.

How is Floor Insulation Applied?

Floor insulation is typically installed via the crawl space in a streamlined process:

Inspection: A technician evaluates the crawl space height and condition to confirm suitability.
Preparation: For PUR foam, a spray gun applies the material in layers to the floor’s underside, including foundation edges to prevent cold bridges. For pearls, material is blown in via a crawl space access point.
Completion: The process is completed in a few hours to a day, depending on the home’s size, with minimal disruption. You can stay in your home during installation.
Ventilation Check: Ventilation grilles are installed if needed to maintain crawl space airflow and prevent moisture issues.
The result is immediate comfort and energy savings.

Is Your Home Suitable for Floor Insulation?

Homes with a crawl space of at least 35 cm are typically suitable for floor insulation. For PUR foam, a minimum height of 50 cm is required, while EPS pearls can be used in spaces as low as 35 cm. Homes built after 1920 often have crawl spaces, making them ideal candidates. If your crawl space is too low or absent, alternatives like bodemisolatie (crawl space floor insulation) may be recommended. A Thuiseco specialist can assess your home’s suitability during a free consultation.

Energy Savings with Floor Insulation

Floor insulation significantly reduces heat loss through the floor, leading to lower energy bills and a more sustainable home. According to Milieu Centraal, you can save up to €360 per year on energy costs with floor insulation, depending on your home’s size and insulation type. The investment typically pays off in a few years, offering returns comparable to a high-interest savings account. Plus, it enhances comfort by keeping floors warm and reducing drafts.
