Corporate Communications

Abrasion resistance

refers to the resistance of solid surfaces against mechanical strain, in particular friction

Acclimation

The 48-hour time period when unopened packages of laminate flooring should be placed in the center of the room in which they will be installed. The acclimation process allows the flooring to stabilize to the room’s temperature; failure to do so can result in the boards shrinking (creating gaps) or expanding (creating peaks).

Acclimatization

laminate should be stored for about 48 hours in the room in which it is laid. In this way, it adapts to the temperature and does not become warped during the laying process.

Circulation groove

notch on the undersurface of laminate flooring that supports the air circulation and therefore prevents mould formation

Emissions

are classified in the different classes E1, E2, E3 (E1 = lowest pollutant emission). The output of formaldehyde is measured. The formaldehyde content of the air is measured in “parts per million” (ppm). The permissible limit value is 0.1 ppm and should not be exceeded. Laminates from SWISS KRONO are of class E1 and are therefore regarded as pollutant-free.

End molding

Used as a transition between floors of unequal heights. Examples: From laminate to carpet or vinyl.

Eventum

EVENTUM laminate flooring (Kronostar Premium Collection Russia) includes wood decors, high quality oak styles in different colour variations.

Expansion

The floor’s reaction as it responds to the room’s temperature and humidity. As temperature or humidity rises throughout the day or year, laminate flooring planks expand outward, which is why the expansion gap – a 3/8 of an inch gap between the floor and perimeter walls — is a critical part of laminate flooring installation.

FSC

Stagger

When installing laminate flooring planks, staggering helps joints disappear into the hue and grain of the surface; repeating the same joint line throughout can call attention by creating a floor-wide pattern. Staggering is accomplished by using a two-thirds-length plank to start the second row and a one-third-length plank to start the third row.

Underlay

insulating support layer, laid between the floor and laminate for sound insulation

Underlayment

Pad installed above the subfloor before laminate planks are installed. The underlayment pad provides sound dampening and levels out minor imperfections in the subfloor.

Utilisation classes

the DIN EN 13329 standard classifies laminate products and is intended as means of orientation for the customer. The utilisation classes are used to classify the laminates according to their resistance: abrasion, shock resistance, light fastness. Which laminate is to be used appropriately for which location of usage is also recommended – for instance commercial areas or private dry and/or wet rooms.

Vapor barrier

A polyethylene film used to prevent moisture from concrete subfloors from seeping into the laminate-wood planks, creating damage.

Vapour barrier
