About underlay
Underlay is the single most under-appreciated component of a good floor. It insulates against cold subfloors, absorbs footfall sound (a legal requirement in flats), evens minor subfloor variance, and — for click floors — protects the click joints from failing early. Spending well on underlay adds 30% to floor lifespan.
