NTCA Consensus Documents Library: Information At Your Fingertips

Last year, NTCA launched a new feature on its website: the NTCA Consensus Documents Library. To visit this excellent resource, click here.

This new resource puts critical documents at your fingertips, including position statements and white papers on a range of industry issues on underlayments and subfloors, tile assemblies and grout joints, and types of tile. More papers will be added as they become available.
