Common Uses

The Winchester Kore Collection is used for whole-home SPC flooring installations where waterproof performance, a condo-approved IIC 79 sound rating, and the convenience of an attached underlay are important.

Pro Tips

Confirm the concrete subfloor is dry before installing -- use a moisture test on any concrete slab.
Do not add a second layer of underlayment.
Leave a 10mm (3/8") expansion gap around all fixed vertical surfaces.

Frequently Asked Questions

Can Kore be installed in a basement?
Yes. The 100% waterproof SPC core is suitable for below-grade basement installations. Ensure the concrete is dry and flat before installing.

What is the IIC 79 sound rating?
IIC 79 exceeds most condo and strata minimum requirements (typically IIC 50-55 or higher). This rating makes the Kore Collection suitable for multi-family buildings where sound transmission is regulated.
