Question
Can my flooring contractor install vinyl planks by gluing them directly to the Truflor subflooring material?

Answer
Thank you for your email Adrian. An underlayment is required under vinyl to avoid telegraphing of any variations in the sub-floor. Hardwood flooring or carpet can be installed without an underlayment but vinyl requires it.
Click here for the APA E30V document which contains the relevant guidelines. In there you will find info on the correct way to install underlayment.
