Side-by-side decision

Compare up to four materials or solutions

Uses, limitations, buying checks, compatibility, care, mistakes and alternatives on one screen.

Start with two options

Compare the right product for the right use, not only package price.

How to compare intelligently

  1. Define actual exposure: dry interior, dampness, direct water, exterior, ground or heat.
  2. Compare the whole system: fasteners, membrane, primer, underlayment, maintenance and service life.
  3. Normalize the unit: piece, linear length, covered area, volume or replacement cycle.
  4. Reject any option that requires improvised compatibility or hiding an existing defect.
