Jumpax Boards vs Plywood: Which Is Best for LVT and Vinyl Flooring?
If you're preparing a floor for Luxury Vinyl Tiles (LVT), vinyl or other resilient floor coverings, one of the biggest decisions is choosing the right subfloor. For years, plywood has been a common choice, but more installers are now choosing Jumpax overlay boards because they are quicker to install, create a smoother surface and remove many of the issues associated with fixing plywood into the subfloor.
In this guide, we compare Jumpax Boards with traditional plywood, explain the key benefits, and help you choose the right Jumpax system for your project.
What Are Jumpax Boards?
Jumpax Boards are specialist overlay boards designed to create a smooth, stable surface for resilient floor finishes such as LVT, sheet vinyl, linoleum, rubber, cork, carpet and carpet tiles.
Instead of being screwed down like plywood, Jumpax systems are installed as a free-floating dual-board system. The base and top boards are bonded together using an integrated adhesive layer, creating a stable surface ready for the final floor finish.
This helps reduce common issues such as:
- Uneven plywood joints showing through thin flooring
- Screw heads or fixings becoming visible
- Damage to pipes, cables or heating systems below
- Dust and mess from cutting, drilling and sanding
- Waiting times caused by wet screeds or smoothing compounds
Why Choose Jumpax Instead of Plywood?
1. Faster Installation
Plywood installation can involve measuring, cutting, drilling, screwing, filling screw holes and sanding joints. Jumpax Boards are much quicker to install because they are laid as a dry, floating overlay system.
This makes them ideal for installers who want to reduce preparation time and move onto the floor finish more quickly.
2. A Smoother Surface for LVT
LVT and vinyl are thin floor finishes, so imperfections in the subfloor can easily show through. Jumpax is designed to provide a smooth and stable surface, helping to reduce the risk of visible joints, uneven areas or imperfections in the finished floor.
3. No Screws, Nails or Mechanical Fixings
One of the biggest advantages of Jumpax over plywood is that it does not need to be mechanically fixed into the floor. This is especially useful where there may be hidden services below, such as:
- Water pipes
- Electrical cables
- Underfloor heating
- Acoustic matting
- Concrete slabs where drilling is not preferred
4. Cleaner and Drier Floor Preparation
Jumpax avoids the need for wet screeds, primers or smoothing compounds in many suitable applications. This keeps the installation cleaner, reduces drying times and allows the project to move forward faster.
5. Better for Acoustic Flooring Systems
Because Jumpax can be installed as a floating overlay board, it works well as part of acoustic flooring systems. This is particularly useful when installing LVT over acoustic underlays, where a firm, smooth load-spreading layer is required above the acoustic material.
Jumpax vs Plywood Comparison
Jumpax is laid as a dual-board floating system. The boards bond together to create a smooth, stable surface without needing screws or nails into the subfloor.
Plywood can provide a suitable surface, but it normally needs mechanical fixing, careful joint preparation, screw filling and sanding before thin floor finishes are installed.
| Feature | Jumpax Boards | Plywood |
|---|---|---|
| Suitable for glue-down LVT | Yes | Yes, if correctly prepared |
| Floating installation | Yes | No |
| Screws or nails required | No | Usually, yes |
| Risk of hitting pipes or cables | None, if correctly installed | Possible when fixing down |
| Suitable with acoustic systems | Yes, when specified as part of the correct acoustic LVT system such as dB Matting 15mm with a suitable Jumpax overlay board. | Limited, depending on system |
| Suitable with underfloor heating | Yes, with the correct Jumpax system and heating build-up | Limited, no test data for this system |
| Installation speed | Fast, self-adhesive, dry installation with no setting time for the board system | Slower, with more fixing, filling, sanding and preparation |
| Dust and mess | Minimal | More gluing, curing, cutting, drilling and sanding |
Acoustic Flooring System for LVT
LVT is a popular floor finish, but because it is thin and hard, it often needs the right acoustic build-up beneath it to help reduce sound transfer. Standard soft acoustic underlays are not always suitable directly below glue-down LVT because the flooring needs a firm, smooth and stable surface.
For this reason, we offer a dedicated acoustic flooring system using:
- 15mm dB Matting
- Jumpax Heat-Pak / Jumpax Basic overlay board
- Glue-down LVT finish
This creates a firm floating overlay above the acoustic layer, giving the LVT a suitable surface while helping improve acoustic performance.
Our supplied acoustic prediction shows a floor build-up of LVT, 7mm Jumpax or ply, 15mm acoustic rubber and 150mm concrete achieving a predicted airborne performance of approximately Rw 55 dB.
Important: This is a predicted result for the specific construction shown and should not be treated as a guaranteed on-site test result. Actual performance can vary depending on the existing structure, installation quality, flanking sound paths and surrounding construction.

Installing Jumpax Boards
Always follow the manufacturer’s installation guidance for the specific Jumpax system being used. As a general overview, the process usually involves:
- Check the subfloor is clean, dry and suitable.
- Allow the boards to acclimatise before installation.
- Lay the correct moisture barrier or PE foil where required.
- Install the baseboards in the correct layout.
- Install the topboards with staggered joints.
- Activate the adhesive bond between the layers.
- Sand joints where required to create a smooth finish.
- Install the final floor covering within the recommended timeframe.

For heated floors, the heating system should be switched off and cooled before installation. The system should only be restarted once the flooring adhesive has fully cured, and the temperature should be increased gradually in line with the heating system guidance.
