Stop Losing Heat
Through Your Roof
In the Netherlands, up to 30% of a home's heat escapes through an uninsulated roof. With Dutch energy prices among the highest in Europe, that translates to hundreds of euros wasted every year on heating that literally goes through the ceiling.
Professional roof insulation is one of the most effective home improvements you can make. The investment typically pays for itself within 3-7 years through reduced energy bills, while also improving comfort, reducing noise, and increasing your property value.
Combined with the Dutch government's ISDE subsidy program, which can cover a significant portion of the installation cost, there has never been a better time to insulate your roof.
Lower energy bills — reduce heating costs by 15-25% from day one
Year-round comfort — warmer in winter, cooler in summer
Higher property value — improved energy label boosts resale price

Insulation Methods
For Every Roof Type
Every Dutch roof is different. Whether you have a pitched tile roof, a flat extension, or a historic canal house, we have the right insulation solution. Our team recommends the most effective method based on your roof construction, budget, and energy goals.
Interior Insulation (Between Rafters)
Mineral wool or PIR boards fitted between roof rafters from the inside. Cost-effective and ideal when the roof covering is still in good condition.
Exterior Insulation (On Top)
Rigid insulation boards applied on top of the roof deck, covered with new roofing. Best performance and no loss of interior space.
Blown-In Insulation
Loose-fill insulation blown into cavity spaces. Fast installation with minimal disruption, perfect for hard-to-reach areas and older roof constructions.
Spray Foam Insulation
Expanding PUR foam sprayed directly onto the roof deck. Creates an airtight seal and excellent R-value, ideal for irregular or complex roof shapes.
Flat Roof Insulation
External insulation boards on flat roofs with new bitumen or EPDM covering. The standard solution for Dutch aanbouw extensions, garages, and modern buildings.
ISDE Subsidies & Energy Savings in 2026
The Dutch government actively encourages homeowners to insulate through the ISDE subsidy program. Combined with significant energy savings, roof insulation is one of the smartest investments you can make for your home.
Subsidies up to €3,000+ — the ISDE 2026 program covers a significant portion of your insulation costs, based on surface area and R-value achieved
Payback period of 3-7 years — with current Dutch energy prices, your insulation investment recovers itself quickly through lower monthly gas and electricity bills
Energy label improvement — insulation can jump your energy label by 1-2 steps, directly increasing your property's market value by thousands of euros
Property value increase — homes with good insulation and a higher energy label sell faster and for higher prices in the Dutch housing market
Tip: Apply for the ISDE subsidy after installation is complete. You need the final invoice and proof of the achieved R-value. We prepare all necessary documentation so you can submit your application immediately after the work is finished.

Frequently Asked Questions
Everything you need to know about roof insulation in the Netherlands.
What is the ISDE subsidy for roof insulation in 2026?
The ISDE (Investeringssubsidie Duurzame Energie) provides subsidies for home insulation in the Netherlands. In 2026, you can receive up to €3,000+ for roof insulation depending on the surface area and insulation value achieved. We help you with the application process.
What insulation methods are available for Dutch roofs?
Common methods include interior insulation (between rafters), exterior insulation (on top of the roof deck), blown-in insulation for cavity roofs, and spray foam insulation. The best method depends on your roof type and construction.
How much energy can roof insulation save?
Proper roof insulation can reduce your heating costs by 15-25%. Since up to 30% of heat escapes through an uninsulated roof, the investment typically pays for itself within 3-7 years through lower energy bills.
What R-value should my roof insulation have?
Dutch building regulations (Bouwbesluit) recommend a minimum R-value of Rc 6.3 m²K/W for new roofs. For renovations, we recommend at least Rc 3.5 m²K/W to qualify for subsidies and achieve meaningful energy savings.
Can you insulate a flat roof from the outside?
Yes. External insulation on flat roofs is very common in the Netherlands. We apply rigid insulation boards on top of the existing roof deck, then cover with new bitumen or EPDM roofing. This method avoids reducing interior ceiling height.
How long does roof insulation installation take?
Most residential roof insulation projects take 1-3 days depending on the roof size and method. Pitched roof interior insulation is typically completed in 1-2 days, while external insulation may take 2-3 days.
