Floor insulation – effective, durable and future-proof solution
- Lower energy consumption and operating costs
- More uniform floor temperatures and better comfort
- Reduced risk of thermal bridges and condensation
- A healthier and more stable indoor climate
Floor insulation plays a crucial role in both energy efficiency, indoor climate and the overall lifespan of the building.
For commercial construction, industry, technical rooms and renovation projects, today there are high demands for low heat loss, minimal space requirement, documentable performance and long durability.
At Dan-iso, we produce highly durable insulation solutions made of PUR (polyurethane) and PIR (polyisocyanurate) – materials that in many applications provide significant advantages compared to traditional insulation materials such as mineral wool, EPS and XPS.
We also offer our environmentally friendly variant, Dan-isoRECY, which is made from recycled polyurethane, providing the same technical properties as standard PUR/PIR, but with a reduced CO₂ footprint.
Why is floor insulation so important?
An insufficiently insulated floor structure can account for a significant portion of the building's total heat loss.
This applies both to new construction and renovation, where older structures often have poorer insulation.
Correct and effective floor insulation can therefore have a major impact on the building's
energy optimization and indoor climate. Good floor insulation contributes to:
* Lower energy consumption and operating costs, * More uniform floor temperatures,
*Reduced risk of thermal bridges and condensation and
*A healthier and more stable indoor climate
PUR and PIR – high insulation performance in minimal space
PUR and PIR insulation are known for their very low thermal conductivity (λ value) compared to mineral wool and other conventional materials.
Comparison (typical values):
- PUR/PIR: approx. 0.022–0.026 W/mK
- Mineral wool: approx. 0.034–0.037 W/mK
This means that the same insulation performance can be achieved with significantly less thickness. For commercial buildings and technical installations, this is often crucial – especially where:
- The building height is limited.
- There are requirements for low construction height
- Existing floors are renovated
Advantages of PUR/PIR over mineral wool and other materials
1. High compressive strength – suitable for floor constructions
PUR/PIR has high compressive strength and is suitable for stressed floors such as industrial, warehouse and technical rooms. Mineral wool is more compressible and often requires additional construction for stability.
2. Low moisture absorption
PUR/PIR are closed-cell and absorb minimal moisture, which reduces the risk of loss of insulation capacity and moisture damage. Mineral wool can lose performance when exposed to moisture.
3. Long life and stability
PUR/PIR retains its insulating properties over time and has high dimensional stability, which minimizes settlement and heat loss.
4. High energy efficiency and low CO₂
The high insulation capacity reduces energy consumption. With dan-iso purRECY, a more sustainable solution based on recycled PUR is achieved without compromising on performance.
