LTX 160mm Polystyrene Fixing Plug 200pcs, Klimas LTX-10 for EPS Insulation Boards

The LTX 160mm polystyrene fixing plug 200pcs box is the Klimas LTX-10 length for a 100 mm insulation board over an old plastered wall, and for a 120 mm board on new brick, block or concrete. It is a hammer-in plastic anchor with a 60 mm plate and a plastic pin, so no metal runs through the insulation.

The right length depends on two things: the thickness of the board and what is already on the wall behind it. Below are the boards the 160 mm length holds and the cases where the next length up or down fits better; the other eight lengths sit in the insulation fixing accessories range.

Which Boards the 160 mm Plug Holds

A plug has to pass through the board, the adhesive bed and any existing plaster, and still reach its full anchorage depth in the wall. Klimas prints the result as a selection table for each length. For the 160 mm plug on brick, block or concrete:

• New or stripped wall (10 mm adhesive bed): boards up to 120 mm with the plate on the surface, or 140 mm with the plate recessed.
• Wall with 20 mm of old plaster (plus the same adhesive bed): 100 mm on the surface, 120 mm recessed.

On aerated concrete blocks the plug must go 50 mm into the block instead of 30 mm, which takes 20 mm off every row: 100 mm surface-fixed and 120 mm recessed on a new wall, 80 mm and 100 mm over old plaster. That puts a 100 mm board on old plaster over aircrete on the 180 mm plug.

Why Choose the LTX-10 at 160 mm

1. Made for a 100 mm board on a plastered wall. A 100 mm board fixed on the surface over 20 mm of plaster is exactly this length's row in the Klimas table, so there is no need to step up to a longer plug.
2. Plastic all the way through. The polyethylene sleeve and glass-fibre reinforced polyamide pin give a point thermal transmittance of 0.001 W/K per plug on the surface and 0.000 W/K recessed — the plugs barely add to the heat lost through a thick board.
3. One drill bit for the whole wall. Every LTX-10 length uses a 10 mm hole, and the European Technical Assessment ETA-16/0509 covers concrete, solid and perforated brick, lightweight block and aerated concrete.
4. A wide plate. The 60 mm plate, with a stiffness of 0.50 kN/mm, spreads the hold across the face of the board.
5. 0.75 kN in solid brick and normal concrete. That is the highest characteristic pull-out the assessment gives the LTX-10.
6. Twenty millimetres more board when recessed. Sunk into the board with Klimas's WK-FT cutter and capped with a polystyrene disc, the same plug takes a 140 mm board on a new wall.

Characteristic Pull-Out by Wall Type

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, Klimas's data sheet starts the 0.75 kN row at C20/25 and the 2026 assessment starts it at C16/20; between those grades, count on 0.50 kN. These are characteristic values. The fixing design divides them by its safety factors, which is why the number of plugs per square metre comes from the design and not from this table.

How to Fit It

With a long plug the hole is drilled through a thick board, so the work is about getting the full depth into the wall rather than into the plaster behind the board:

1. Bond the boards first. The plug only resists wind suction; the adhesive carries the insulation.
2. Drill 10 mm through the board into the wall where adhesive sits behind it, reaching at least 40 mm into solid material (60 mm into aerated concrete). Old plaster does not count towards that depth.
3. Use rotary drilling only in perforated brick, hollow block and aerated concrete, so the inner webs the plug grips stay intact.
4. Clear the dust by running the drill in and out of the hole four times at low speed.
5. Seat the plug until its plate lies flush with the board face, then drive the pin with one set of hammer blows and leave it — a set pin is not driven again.

Plugs and wall edges stay at least 100 mm apart, and the plates need covering with mesh and base coat within six weeks of fixing. The guide to installing insulation fixings goes through a whole elevation.

Recessed Fixing

For a recessed fixing, Klimas cuts a recess into the board with its WK-FT cutter, sets the plate flush with the bottom of the recess, drives the pin and closes the recess with a polystyrene disc. The "recessed" columns in the selection table assume this method. Recessing gains 20 mm of board on every row and lowers the point thermal transmittance from 0.001 to 0.000 W/K.

Choosing Between the LTX Lengths

The full Klimas selection table for the lengths Renders World stocks, on brick, block or concrete. "New wall" allows a 10 mm adhesive bed; "old plaster" allows 10 mm of adhesive and 20 mm of existing 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 (this box)	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 (100 per box)	180 mm	200 mm	160 mm	180 mm

Where the old plaster or render is thicker than 20 mm, add the extra to the board thickness and read the table again. The plug length calculator does the same sum for any build-up.

Is 160 mm the Right Length?

• Yes for 100 mm EPS insulation boards fixed on the surface over about 20 mm of old plaster, or 120 mm boards on a new or stripped wall.
• Go down to 140 mm for 100 mm boards on a new wall with the plate on the surface.
• Go up to 180 mm for a 120 mm board over old plaster, or for a 100 mm board over old plaster on aerated concrete.

LTX 160 mm Plug — Questions Before You Order

Will it hold a 100 mm board?

Yes. With the plate on the surface it holds a 100 mm board on every wall type in the table except old plaster over aerated concrete, where the plate has to be recessed. On a new wall the shorter 140 mm plug already holds a 100 mm board.

How many boxes for a wall?

Klimas recommends at least 6 plugs/m² in the middle of a wall and 8/m² in the corner zones up to 15 m high. One box of 200 covers about 33 m² at 6/m² (200 ÷ 6) and 25 m² at 8/m² (200 ÷ 8); a 100 m² main wall at 6/m² takes 600 plugs, which is three boxes.

Does it change above 15 metres?

Yes. The minimums rise to 8/m² in the middle of the wall and 10/m² at the corners, so one box covers 25 m² and 20 m². The insulation design for the building sets the final count.

Can I use it on perforated brick or Porotherm?

Yes, with rotary drilling only. The characteristic pull-out is 0.60 kN in vertically perforated clay brick and 0.40 kN in Porotherm 25 block, against 0.75 kN in solid clay brick — lower values that the fixing design has to allow for.

Which insulation is it for?

Klimas recommends the LTX-10 for EPS and XPS polystyrene boards. For stone wool slabs, use the fixing named in the wool insulation system's own schedule.

Do the plugs carry the weight of the boards?

No. The assessment covers wind suction only. The adhesive bed holds the boards on the wall, and the plugs stop wind pulling them off.
