What underlayment is recommended to be used with radiant heating systems?
Cork is the traditional, most well-known choice for underlayment. It’s known for its excellent insulation properties, which is vital when it comes to creating a barrier between a radiant heating system and a cold concrete slab.
Can you put a wood floor over radiant heat?
Solid hardwood floors can be used over radiant heat systems. However, when using anything wider than 4″ consider extra acclimation and use a hardwood floor glue that is recommended by the wood floor manufacturer. Quartersawn or riftsawn are also considered better hardwood floor choices.
How thick should underlayment be?

What goes over subfloor?
Underlayment: Some types of flooring can be installed directly on top of the subfloor, such as vinyl flooring. Other types need a middle layer, called underlayment, such as laminate,carpet and tile.
Does underlayment help with heat?
Insulating underlayments, like CeraZorb, provide a thermal break between a subfloor and the heating elements, which can help prevent “heat sink” and increase energy efficiency. This can be particularly beneficial if you are trying to heat a room above a cement slab or above an unheated garage.
What is R value in flooring underlayment?
An underlayment which has a value of 3 ft²*°F*hr./BTU will typically be represented as R-3. To put this in perspective, the typical R-value of a bat hitting fiberglass insulation is R-3 to R-5. Many polyethylene foam products have an R-value of 2-3, such as laminate flooring underlayments.
What type of floor is best for radiant floor heating?
The best type of flooring to use with underfloor heating is tile and stone. Tile and stone have high thermal conductivity, meaning that the heat from an underfloor heating pipe or wire transfers to the floor surface quickly. Tile and stone also retain heat well making the system efficient.
What type of flooring is best for radiant heat?
Porcelain and ceramic tile are widely regarded as the best choice for radiant floor heating. These tiles are thin and conduct heat extremely well. This reduces the energy (and time) needed to warm up a room. Tile will also retain the heat longer than other types of flooring, increasing your efficiency even more.
What wood flooring is suitable for underfloor heating?
Engineered hardwood flooring
Engineered hardwood flooring is the most compatible wood flooring for underfloor heating systems and it looks exactly the same as solid wood flooring. Once you have installed it, it feels the same underfoot, too.
What is the difference between underlayment and subfloor?

Not just any hardboard will do, however.
What size plywood is best for subfloor?
The recommended thickness of the plywood subfloor is governed by the spacing of the joists. Some experts suggest that 15/32-inch plywood should be standard if the underlying floor joists are spaced 16 inches apart or less, but slightly thicker 3/4-inch plywood should be used for joists spaced further apart.
Do you need two layers of subfloor?
The subfloor has to be attached to the joists, and two subfloor layers glued together or just nailed through to the joists, is no different than one thicker subfloor layer.
Is it better to use OSB or plywood for subfloor?
OSB has a lower resale value than plywood due to its lower strength. For this reason, few homeowners prefer OSB in their homes. Apart from costs, plywood is superior in all the other areas, such as the strength of the structure. For this reason, it’s a superior material for use on the subfloor.
What type of plywood is used for underlayment?
Lauan Plywood, when used as an underlayment, should be Type 1 (Exterior). The best grade is BB and the next best is CC, while OVL (overlay grade) is the minimum acceptable face grade.
Is Luan a good underlayment?
Luan, a thin plywood underlayment material, is lightweight and easy to install. While luan provides a smooth surface on which to install vinyl, it’s not suitable for all types of vinyl flooring.
