Yes, you do need insulation under a heated floor. Heat rises, so if the insulation is not installed underneath the floor, the heat will be lost and nothing will be gained by installing the floor in the first place.
A thick layer of insulation prevents the heat underneath the floor from being wasted. Good insulation should provide a barrier between the ground and the floor to ensure the heat stays in the room, rather than escaping outside.
It also helps to reduce energy consumption associated with the heating system. Installing a layer of insulation ensures that the heated floor will function efficiently and effectively, providing the desired level of warmth and comfort.
What material is used for underfloor insulation?
Underfloor insulation is typically made from materials such as polystyrene, polyurethane foam, cellulose, and mineral wool. Polystyrene is one of the most common underfloor insulation materials, as it can easily be cut and shaped to fit the area without adding too much bulk.
Polyurethane foam insulation, on the other hand, provides superior insulation compared to that of polystyrene and can also be used to fill small cavities and gaps. Cellulose insulation is made from shredded newspaper, cardboard, or blankets that have been treated to make them fire-resistant, and is usually made up of recycled materials.
Lastly, mineral wool insulation is created using basalt rock and recycled slag, making it one of the most eco-friendly insulation materials. It is also highly resistant to water, mold, and insects.
No matter which type of insulation material is chosen, it is important to ensure that it is properly installed and secure. This can often be accomplished with glue or other adhesive products, or through the use of staples, nails, or screws.
Additionally, all insulation products should have a vapor barrier installed over them to prevent any heat or moisture from entering the room and compromising the insulation.

How do I insulate my floor heating?
It is important to ensure your floor heating is properly insulated in order to maximize efficiency. The best way to insulate a floor heating system is by using a specific floor heating insulation board, either pre-cut boards designed to fit the area or custom boards that need to be cut to size.
Depending on your floor material, such as concrete or wood, you may need to add a layer of underlayment as well. In concrete floors, you should also cover the insulation with a specially designed floor screed.
The floor insulation should be fitted tightly around the pipes and taped securely with appropriate sealing tape. Finally, cover the insulation with a thin layer of mortar and fill the joints with gravel.
This will provide further insulation and prevent hot spots in the floor heating system.
What type of insulation goes under concrete slab?
An often used type of insulation that is installed underneath a concrete slab is extruded polystyrene (XPS). XPS is a dense, waterproof material usually sold in board form that is easy to cut and fit properly underneath the slab.
The key advantage to using XPS is that it acts as a thermal break which prevents heat from entering into the building and also stops condensation. XPS also has excellent compressive strength, meaning it can withstand heavy loads without losing its shape.
To ensure that the insulation is properly installed, the boards should be carefully placed and taped down along the outer perimeter of the slab, and then covered with a waterproof membrane. Additionally, it is important to make sure there is at least a 2-inch air gap between the insulation and any pipes that may be running underneath the slab as this will help to avoid any potential moisture build up and reduce the risk of mould from developing.
How thick is a heated floor?
The thickness of a heated floor will depend on the type of flooring material that has been selected. Typically, heated floors are comprised of either electric radiant heat systems or hydronic (water) radiant heat systems.
Electric radiant-heat systems typically feature a mat of thin wire, a thin layer of insulation, and a thin aluminum heat diffusion plate. This system generally requires a minimum subfloor thickness of 1 1/8”, making the overall heated floor thickness 1 1/2” to 1 3/4”.
Hydronic radiant heat systems involve embedding thin PEX tubing in the subfloor or in a layer of cement. This system does not require any additional materials and only the subfloor or cement needs to be installed, making the overall thickness of the heated floor from 1” to 1 1/2”.
When selecting flooring materials for a heated floor, thinner materials (such as carpet, vinyl, or laminate) are typically used to reduce the overall thickness of the floor. It is important to note that any additional materials used in the heated floor installation, such as tile backer board, could increase the overall thickness of the floor.
Can I put insulation under floor tiles?
Yes, you can put insulation under floor tiles. This is a process known as ‘floating insulation’, and it is becoming increasingly popular in modern buildings. It involves the use of insulation boards or mats which are laid under for tiles, usually with a vapour barrier to prevent moisture damage.
