A Guide to Laying Underfloor Heating Under Laminate

Our screed specialists are regularly asked whether laminate is a good flooring finish for underfloor heating. The simple answer is a resounding ‘yes’! But the manner of its application is terrifically important. Key to gaining the maximum benefits from underfloor heating is the use of effective thermal conductors. In this guide, we survey how to maximise on rapid heat response with laminate flooring.

What is Laminate Flooring?

It’s a synthetic flooring that is constructed to look like wood. Each plank of laminate is made up of synthetic layers and topped with a surface that looks like the real thing. This makes it cheaper than wood flooring, and easier to install. Laminate has always been extremely popular with DIYers because it’s easy to lay, even if you only have basic skills.

Laminate Flooring Requires an Appropriate Underlay

Underlay is essential if you’re installing laminate flooring. Choosing the right kind of underlay is important because it requires efficient thermal conductivity. A rapid heat response is essential to the efficient heating of a room from underfloor heating. RB Liquid Screed would always recommend an extremely low tog, thin underlay. Look for products that guarantee good heat conduction, and – in the case of laminate flooring – noise reduction.


A Liquid Screed Sub Floor is the Right Foundation

If you’re laying underfloor heating, the sub floor is key to the transference of heat from the pipes to the room above. At RB Liquid Screed  we always use liquid screed. Why? Because liquid screed confers a range of benefits, including:

  • Fast installation
  • Small facilitation team
  • Rapid dry – 24/48 hours before light foot traffic
  • 7 days before force drying
  • Excellent finish and enhanced heat conductivity

Laying Underfloor Heating Under Laminate For Excellent Results

Having assembled the right materials for your underlay and flooring finish, it’s important to understand the process of installation. We’ve broken it down into 5 steps:

Step 1. Ensure that the liquid screed sub floor is completely dry before applying the flooring finish. This requires 24/48 hours for initial dry.

Step 2. 7 days later the screed can be force dried using the underfloor heating system. Acclimatise the laminate flooring to the heating temperature in which it will be laid for 48 hours.

Step 3. Lay the underfloor, ensuring that it’s a thin, low tog product.

Step 4. Lay the laminate flooring on top of the underlay.

Step 5. Once the installation is complete, maintain the underfloor heating temperature for at least another 48 hours before turning it off or regulating it.
