FAQ

Why do the click grooves open?

Click latches only open if the panels cool down! This can be caused by the following reasons:

  • The click connections have not been cleanly locked into place – no “click”! (just pressed together / were dirty)
  • The click connections have been damaged during the locking process (banged in)!
  • The panels have become very warm and warped (e.g. by the sun!) – this means the click groove has unlocked (possibly damaged) – this comes undone when cooled!
  • The panels have been fitted during the summer when warm – they are cooling down and are blocked by heavy objects, adhesive cement joints, panels in door frames, etc.!
  • The underlay matting is too soft and too thick! Panels are pressed together, warped and unlocked.

The floor is warped or rippled!

The flooring only ripples if the panels heat up and cannot adjust! This can be caused by the following reasons:

  • The panels were fitted when cold!
  • The panels are exposed to direct sunlight and are distending!
  • The panels are illuminated by strong spotlights or spots and have warmed up as a result (exhibition rooms, for example!)
  • Contraction joints can be found on the underlay matting (e.g. in the cement screed), which are covered with panels!

Click connections are warped! This can be caused by the following reasons:

  • The panels were not carefully locked together. Instead they were banged in!
  • The click groove was dirty when it was locked into place!
  • The panels have warmed up a lot and cannot adjust!
  • Contraction joints can be found on the underlay matting (e.g. in the cement screed), which are covered with panels!
  • The underlay matting is too soft and too thick! Panels are pressed together, warped and unlocked.

The floor smells unpleasant!

Unfortunately, it is not possible to produce vinyl which is completely odour-free. According to DIN EN 16000 guidelines, these odours must have subsided to such a degree within 28 days that they are no longer offensive.

Are the odours harmful?

No! According to the TÜV test report in accordance with DIN EN 16000 of the French VOC directive, our panels were confirmed to have been licensed with the best class A+ for living areas.

What substances do the panels contain?

Result [mg/m3] Class A+
Formaldehyde 5 A+ < 10
Acetaldehyde 10 A+ < 200
Toluene 16 A+ < 300
Tetrachloroethene n.d. A+ < 250
Xylene n.d. A+ < 200
1,2,4- Trimethylbenzene n.d. A+ < 1000
1,4- Dichlorbenzene n.d. A+ < 60
Ethylbenzene n.d. A+ < 750
2-Butoxyethanol n.d. A+ < 1000
Styrene n.d. A+ < 250
TVOC 37 A+ < 1000

What thermal resistance do the vinyl floorings have?

According to EN 12664 / EN12524, the thermal resistance of our vinyl panels (5 mm) is 0.067 m2•K/W

Definition of thermal resistance:
Rth = ∆T / Qv
∆T = Temperature difference
Qv = Thermal flow
Definition of thermal conductivity:
λ = l / (Rth • A)
The unit of thermal resistance is K/W (Kelvin / Watt)

Advantage of calculation with “thermal resistance”:
The values of the individual flooring layers can be added together!
Underfloor heating systems: The total of the values of all floorings should not exceed 0.15 m2•K/W

Comparatives: 25 cm concrete flooring Rth = 0.10 m²•K/W
7 cm underlay flooring with cement Rth = 0.05 m²•K/W
DBCover 1510 underlay matting Rth = 0.051 m²•K/W
25 mm chipboard Rth = 0.171 m²•K/W
30 mm solid spruce wood Rth = 0.231 m²•K/W
Ceramic panels (tiles) Rth = 0.010 m²•K/W

Is the floor anti-static?

According to the test report, the maximum static electricity for our vinyl panels is 1.84 kV! According to EN 1815, the maximum static electricity must not exceed 2 kV if the floor is to be listed as “anti-static”! As a result, the floor is anti-static!

Attention: In particularly sensitive applications (operating theatres, production rooms for electronic components, etc.) lower values are required!

The panels have lippage or slight cracks!

According to EN 649 and EN 651, the tolerance for PVC floorings is 0.2 mm (approx. 2 x the thickness of a business card), meaning only higher lippage or wider cracks are rejected.

The flooring has defects in the pattern, is warped, etc.!

According to the applicable norms, when the light is shining vertically from above or behind, the defect must be visible from approx. 1.80 m high (eye-height) to approx. 2.40 m in front of a toecap in order for a complaint to be upheld. Defects which can only be seen in backlight from knee-height cannot be rejected!

What usage class (EN 685) are the panels assigned to?

  • Panels with 0.1 mm wearing surface: Usage class 21
  • Panels with 0.3 mm wearing surface: Usage class 23/31
  • Panels with 0.5 mm wearing surface: Usage class 33/42

Living – areas which are intended for private use
  • 21 moderate / low: Areas with low or intermittent use, bedroom
  • 22 normal / average: Areas with average use, living rooms, entrance halls
  • 23 strong: Areas with intensive use, living rooms, entrance halls, dining rooms and corridors

Commercial – areas which are intended for public and commercial use
  • 31 moderate: Areas with low or intermittent use, hotels, bedrooms, conference rooms, small offices
  • 32 normal: Areas with average traffic, classrooms, small offices, hotels, boutiques
  • 33 heavy: Areas with heavy traffic, corridors, shopping centres, lobbies, schools, large offices
  • 34 very heavy: Areas with intensive use, multi-purpose halls, halls, shopping centres

Industrial – areas which are intended for use by light industry
  • 41 moderate: Areas, in which work is mainly carried out sitting down and where light vehicles are occasionally used. Electronics workshops, precision mechanics workshops
  • 42 normal: Areas, in which work is mainly carried out standing and / or with vehicles. Warehouses, electronics workshops
  • 43 heavy: Other industrial areas, warehouses, production halls

To which wear group do our vinyl panels belong (EN 660-2)?

Our vinyl panels belong to Group T

2.1 Classification of flexible flooring

2.1.1 EN 649, Classification of homogeneous and heterogeneous PVC floorings

In the first step, Table 1 determines what wear group the flooring should be allocated to.

Table 1
Wear group T P M F
Thickness loss mm EN 660-1 ≤ 0,08 ≤ 0,15 ≤ 0,30 ≤ 0,60
Volume loss mm³ EN 660-1 ≤ 2,0 ≤ 4,0 ≤ 7,5 ≤ 15,0

Floor coverings with transparent wearing surface automatically belong - without inspection - to Wear Group T!
