When installing vinyl plank flooring, the method you choose plays a major role in how your floor performs and looks over time. One of the most reliable techniques used across the industry—and the preferred method for Biyork’s vinyl collections—is the Unilin angle-angle installation, sometimes called Unilin angle/angle click-lock installation.
This approach is designed specifically for modern click-lock vinyl flooring, giving homeowners and professionals a clean, tight install with long-term stability.
In this guide, we’ll walk through:
- What Unilin angle-angle installation is
- Why Biyork vinyl flooring works beautifully with this method
- Step-by-step installation tips
- Practical advice for long-term performance
What Is Unilin Angle-Angle Installation?
Unilin Angle-angle installation is a technique used for floating vinyl flooring where each plank is installed by angling it upward, inserting it into the locking groove of the previous plank, and then gently lowering it to snap into place.
This motion securely engages the click-lock system, creating:
- Tight seams
- A stable floating floor
- A cleaner visual finish
- Less need for force or tools compared to horizontal pressure locking
This method ensures the locking mechanism engages perfectly for a long-lasting fit.

Biyork’s HydroGen 5 and HydroGen 6 Plank and Tile vinyl collections are engineered specifically for floating installation using Unilin angle-angle engagement.
1. Stronger Joint Integrity
The Unilin angle-angle technique fully engages the locking profile, helping prevent:
- Separation
- Gapping
- Peaking
- Shifting from seasonal expansion
2. Ideal for Floating Floors
Vinyl plank flooring is designed to float, and Unilin angle-angle installation keeps the floor secure while allowing natural movement.
3. Smoother, Cleaner Seams
The gentle lowering motion reduces strain on the locking system and results in crisp, tight seams that show off Biyork’s textures and colors.
4. Faster and More Accurate
Installers appreciate this technique because it reduces mistakes and improves alignment, especially in longer rows or large rooms.
Step-by-Step Guide: Unilin Angle-Angle Installation for Biyork Vinyl Floors
1. Prepare the Subfloor
A proper surface ensures a flawless result. Make sure the subfloor is:
- Flat
- Clean
- Dry
- Free from debris
Install underlayment if required. HydroGen 5 and HydroGen 6 include integrated acoustic and comfort underlayment, reducing noise and enhancing underfoot feel.
2. Create Your Starting Line
Use a chalk line or laser guide to ensure your first row is perfectly straight. Correct alignment in your first row makes the entire installation smoother.
3. Begin the First Row
Lay your first vinyl plank with the tongue facing the wall. Use spacers to maintain the required expansion gap along the perimeter.
4. Angle Into Place
This is the core of the method:
- Lift the next plank at roughly a 20–30° angle
- Insert the tongue into the groove of the previous plank
- Slide to align the edges
- Slowly lower the plank until it locks with a clean “click”
Repeat for each plank in the row.
5. Maintain Proper Staggering
A randomized stagger creates a more natural hardwood look. To enhance stability and visual flow:
- Stagger end joints by at least 12 inches
- Avoid repeating patterns or tight alignment
6. Use Tapping Tools Only When Necessary
If a plank doesn’t fully seat:
- Use a tapping block
- Gently assist the joint
- Never hammer directly on the locking system
7. Complete the Perimeter
After all planks are installed:
- Remove spacers
- Install baseboards or quarter round
- Ensure trim does not press down tightly on the floor (it must float)
Pro Tips for Best Results
Acclimate, It’s Necessary: Vinyl products perform best when acclimated to the room’s temperature. Follow Biyork’s product-specific guidelines.
Check Lighting: Installers often check seams under strong lighting to ensure the lock is fully seated—especially important with textured vinyl.
Plan Around Door Frames: Unilin Angle-angle installation can be more challenging near tight spaces. When needed, remove the door casing or use horizontal tapping techniques to finish the last piece.
