What insulation do I need for concrete floor?
EPS is a good choice for insulating a concrete floor because it has a long term R-value, alongside a consistent level of thermal resistance, and it is produced in easy to manage sheets to allow easy installation.
Do I need to insulate my concrete slab?
To ensure that the foundation of your home isn’t a major source of heat loss, you should install rigid insulation before pouring concrete. Doing this protects the concrete from moisture as well as keeps heat inside the home and is required by many modern building codes.
Can you put kingspan in a concrete floor?
Our range of optimum, premium and high performance floor insulation products are suitable for use in a range of solid concrete floor applications.
How thick should floor insulation be UK?
The U-value is a measure of how quickly heat will travel through the floor. To achieve this standard, you will normally need at least 70mm of high-performance foam insulation, or 150mm of mineral wool, but this will vary depending on floor type, shape and size.
How thick should concrete floor insulation be?
A 50mm thick layer of proprietary floor slab insulation (e.g. 50mm Kingspan, Celotex or similar) is usually enough to reach and maintain the target U value but this should be checked with an architect first. Insulation sheets should be laid tightly together with the joints staggered to avoid movement.
Can you lay Celotex on concrete?
As upper mentioned, Celotex GA 4000 insulation boards can have a number of different application, why they can be successfully installed in concrete slab floors, beam and block floors and suspended timber floors, which will all be discussed right here.
What R-value should floor insulation be?
Recommended insulation levels for retrofitting existing wood-framed buildings

|---|---|---|
| Uninsulated Attic | ||
| 3 | R30 to R60 | R19 to R25 |

How do you lay an insulated concrete floor?
How to Lay a Concrete Floor with Insulation

- Lay Your Damp-Proof Membrane.
- Add Your Insulation.
- Concreting.
How do you install a damp proof membrane on a concrete floor?
Damp in Concrete Floors
- Dig up the old concrete floor, install a new damp proof membrane and lap up edges before replacing the concrete slab.
- Fully isolate the dampness in the floor using a surface Damp Proof Membrane (DPM)
What is the minimum R-value for floors?

When did building regulations require floor insulation?
1990
INTRODUCTION. While it has long been common practice to insulate upper floors to reduce noise and to cut heat loss, only since 1990 have Building Regulations required that ground floors be insulated in order to save energy.
