Flooring, Carpets & Rugs Glossary Terms
2 terms related to flooring, carpets & rugs, explained in plain English.
What Does AC Rating Mean for Laminate Flooring?
AC (Abrasion Class) rating, from AC1 to AC5, indicates how much foot traffic and wear laminate flooring is designed to withstand, tested under a European standard. AC1-AC2 suits light domestic use such as bedrooms, AC3-AC4 suits busier living areas and light commercial use, and AC5 is rated for heavy commercial traffic — so matching the rating to the room's footfall helps the floor last as expected.
What Does Tog Rating Mean for Carpet Underlay?
Like duvets, carpet underlay is rated in tog for thermal insulation — a higher tog underlay helps retain more heat in the room, which can meaningfully reduce heat loss through ground floors. Underlay tog is separate from its cushioning/support properties, so a product is generally chosen by balancing its tog rating against the right density and thickness for the carpet and traffic level above it.
