EXTRA
Foamed polystyrene sheets TENAPORS EXTRA are particularly recommended in places with increased humidity: roofs, “cut” roofs, underground sections of buildings (basement floors, foundations up to 6 m depth, floors).
Foamed polystyrene sheets TENAPORS EXTRA are manufactured in automatic pressform machine, thermally expanding previously foamed polystyrene granules.
The sheets are of a porous material with closed pores and anti-pyrene additives (self-extinguishing substances).
The sheets resist weaker acids, and alkaline, they do not resist aromatic thinners and thinners containing halogens, or other substances such as esters, ketenes, oils, or lubricants.
Marking. The marking code for TENAPORS EXTRA EPS 150 is determined by a harmonised European standard and it can be described by the following example: EPS – EN 13163 - T2 - L2 - W2 – S2 – P4 - BS 200 - CS(10) 150- DS(N) 2 – DS(70,-)1 – WL(T) 1
| No. | Parameter | Standard | Tolerance | Class or marking in compliance to LVS EN 13163:2004 |
|---|---|---|---|---|
| 1. | Length | 1200 mm | ±2 mm | L2 |
| 2. | Width | 600 mm | ±2 mm | W2 |
| 3. | Thickness | 30, 40, 50, 60, 80, 100mm | ±1 mm | T2 |
| 4. | Perpendicularity | ±2/1000 mm | ±2/1000 mm | S2 |
| 5. | Flatness | ±5 mm | ±5 mm | P4 |
| 6. | Stability of sizes under continuous normal laboratory conditions (23ºC, 50% relative humidity) | ±0,2% | ±0,2% | DS(N)2 |
| 7. | Stability of sizes under certain temperature and humidity conditions, 48 h, 70°C | <1% | <1% | DS(70,-) 1 |
| No. | Parameters | Standard | Level |
|---|---|---|---|
| 1. | Stopper load, if relative deformation is 10%, kPa | ≥150 | CS(10) 150 |
| 2. | Bending strength, kPa | ≥200 | BS 200 |
| 3. | Long-term water absorption under complete immersion in water | ≤1% | WL(T) 1 |
| 4. | Burning, Euro class TENAPORS EXTRA | E | E |
| 5. | Heat conductivity coefficient at 10°C, λ D,W/m·K | 0,035 | 0,035 |
