Description
The LTX 220mm polystyrene fixing plug 100pcs box holds a 180 mm insulation board on new or stripped brick, block or concrete, and a 160 mm board where about 20 mm of old plaster is still on the wall. It is the longest Klimas LTX-10 length Renders World stocks, and the only one packed 100 to a box.
Each plug is a plastic sleeve with a plastic pin and a 60 mm plate, driven in with a hammer. Shorter lengths, all 200 per box, are in the insulation fixing accessories range.
Boards the 220 mm Plug Fixes
The Klimas selection table for brick, block and concrete gives this length:
| Wall | Plate on the board face | Plate recessed |
|---|---|---|
| New or stripped wall, 10 mm adhesive bed | up to 180 mm | up to 200 mm |
| Old plaster of 20 mm plus the adhesive bed | up to 160 mm | up to 180 mm |
The 2026 assessment's formula confirms it: 220 − 10 − 30 = 180 mm on a new wall, and 220 − 30 − 30 = 160 mm when old plaster sits behind the adhesive.
On aerated concrete the plug needs 50 mm in the block, so 20 mm comes off every figure: 160 mm on the surface or 180 mm recessed on a new wall, 140 mm or 160 mm over old plaster.
100 Plugs per Box — What It Means for Your Order
Every LTX length from 70 mm to 200 mm comes 200 to a box; at 220 mm the box holds 100. Klimas's own table packs it the same way. On a deep-insulation job that halves the area one box covers, so count boxes from the number of plugs, not from habit.
- At 6 plugs per m² one box covers about 16 m².
- At 8 plugs per m² one box covers 12.5 m².
- For 100 m² of wall at 6 to 8 per m² you need 600 to 800 plugs — six to eight boxes.

Characteristic Pull-Out by Wall
| Wall | Drilling | Characteristic pull-out |
|---|---|---|
| Concrete C12/15 | hammer | 0.50 kN |
| Concrete C20/25 to C50/60 | hammer | 0.75 kN |
| Solid clay brick | hammer | 0.75 kN |
| Calcium silicate solid brick | hammer | 0.60 kN |
| Calcium silicate hollow block | hammer | 0.60 kN |
| Vertically perforated clay brick | rotary only | 0.60 kN |
| Porotherm 25 perforated block | rotary only | 0.40 kN |
| Lightweight concrete block | rotary only | 0.60 kN |
| Aerated concrete, density from 0.35 kg/dm³ | rotary only | 0.50 kN |
| Aerated concrete, density from 0.65 kg/dm³ | rotary only | 0.60 kN |
For concrete, the 0.75 kN row starts at C20/25 in the Klimas sheet and at C16/20 in the 2026 assessment; where the concrete grade is in doubt, use 0.50 kN. Values are characteristic: the plug count per square metre comes from the fixing design and its safety factors.
Installing the 220 mm Plug
- Bond the boards first. The adhesive holds them; plugs only resist wind suction.
- Drill 10 mm through the board where adhesive is behind it, then at least 40 mm into the wall, or 60 mm into aerated concrete. On a 180 mm board that is a deep hole, so use a bit long enough to reach the bottom.
- Switch the hammer off for perforated brick, hollow block and aerated concrete.
- Clean the hole with four slow in-and-out passes.
- Set the plate flush and drive the pin home at once. A driven pin is not struck a second time.
Keep 100 mm between plugs and from wall edges, fix at 0 °C to +40 °C, and cover the plates with mesh and base coat within six weeks. The guide to installing insulation fixings shows the order for a full wall.
Recessed Fixing at 220 mm
Klimas's WK-FT cutter sinks the plate into the board; after the pin is driven, a polystyrene disc covers it. That stretches this length to a 200 mm board on a new wall and 180 mm over old plaster, with 0.000 W/K per plug.
All LTX Lengths and What They Reach
Selection table for the nine stocked lengths on brick, block or concrete. "New wall" counts a 10 mm adhesive bed; "old plaster" counts that bed plus 20 mm of plaster.
| Plug | New wall, surface | New wall, recessed | Old plaster, surface | Old plaster, recessed |
|---|---|---|---|---|
| 70 mm | 30 mm | 50 mm | 10 mm | 30 mm |
| 90 mm | 50 mm | 70 mm | 30 mm | 50 mm |
| 110 mm | 70 mm | 90 mm | 50 mm | 70 mm |
| 120 mm | 80 mm | 100 mm | 60 mm | 80 mm |
| 140 mm | 100 mm | 120 mm | 80 mm | 100 mm |
| 160 mm | 120 mm | 140 mm | 100 mm | 120 mm |
| 180 mm | 140 mm | 160 mm | 120 mm | 140 mm |
| 200 mm | 160 mm | 180 mm | 140 mm | 160 mm |
| 220 mm (this box, 100 per box) | 180 mm | 200 mm | 160 mm | 180 mm |
For plaster deeper than 20 mm, add the extra to the board before reading across, or use the plug length calculator.
Is 220 mm the Right Plug?
- Yes for 180 mm EPS insulation boards on a new or stripped wall, 200 mm recessed, or 160 mm boards over about 20 mm of old plaster.
- Choose 200 mm for 160 mm boards on a new wall — you get 200 plugs per box.
- Choose 180 mm for 140 mm boards on a new wall.
LTX 220 mm Plug — Questions
What is the thickest board it fixes?
200 mm on a new or stripped wall, with the plate recessed. With the plate on the surface it is 180 mm; over old plaster 160 mm on the surface and 180 mm recessed.
How many boxes for 100 m²?
Six at Klimas's minimum of 6 plugs per m², eight if the whole wall were fixed at the corner rate of 8 per m² (walls up to 15 m). Above 15 m the minimums rise to 8 and 10 per m². The insulation design gives the final number.
Why only 100 per box?
That is how the length is packed in Klimas's selection table: 200 per box up to 200 mm, 100 per box from 220 mm. When comparing prices with shorter lengths, compare per plug.
Does it work in aerated concrete?
Yes, with rotary drilling and 50 mm of anchorage — a 160 mm board on the surface of a new wall or 180 mm recessed. Pull-out is 0.50 kN in blocks from 0.35 kg/dm³ and 0.60 kN from 0.65 kg/dm³.
Which insulation is it for?
Klimas recommends the LTX-10 for EPS and XPS polystyrene boards. Stone wool needs the fixing given in the wool system's instructions.
Do the plugs carry the boards' weight?
No. The adhesive carries the boards; the assessment covers the plugs for wind suction only.
