Nozzles and blowing accessories
We differ between the following seven blowing injection methods:
- Open/attic blowing
- Dense blowing/insulating needle technique
- Dense blowing with ventilated rotary nozzle
- Dense blowing with ventilated injection lance
- Damp spraying/CSO
- Cavity wall insulation with injection nozzles
- Element filling
For most blowing injection methods, injection tools and/or auxiliary devices such as injection bezels or sealing sponges are necessities. We provide tools for every method.
Furthermore, an injection hole must be made (e.g. with a hole saw) which needs to be resealed. To solve that problem, we provide closing solutions – sealing corks and wood fibre closing plugs.

Injection Bezels, Clamping Connectors and Sealing Sponges
Injection bezels are used for hose blowing and working with injection lances. They ensure a dust-reduced blowing injection and flowing movement with the hose or the lance. Damage to the building element is also avoided.
Clamping connectors make blowing numerous injection holes in serial arrangement easier. Ventilated clamps are used when the building element has not got enough ventilation.
Sealing sponges are used for dust-reduced hose blowing.
Injection Nozzles and Rotary Nozzles
Fixed injection nozzles are particularly suitable for blowing injection holes into cavity walls and for the insulation of small box sections.
Rotary nozzles are essentially injection nozzles with a pivot bearing. This enables the comfortable rotation of the nozzle outlet using a handle possible.
For large cavities, this function is absolutely crucial because only this method the material flow can be directly reach a homogeneous agglomeration which conforms to the requirements licence.
Insulating Needles with Piercing Head
A bent pipe used for insulating behind vapour barriers and other membranes, as well as for insulating hard boarded cavities (with a sufficiently large injection hole). Specially shaped head for piercing membranes.
- Allows precise injection even into remote areas of cavities.
- Easy redensification due to new design
- Excellence sealing by smooth finish
- Material: Aluminium
Ventilated Rotary Nozzles: X-Jet, J-Jet and S-Jet
Ventilated rotary nozzles can fill stud-wall constructions with insulation material and conduct excess air controls.
During this process, the insulation material flowing with the injection air is accelerated by inflow into the rotary nozzle.
Ventilated Injection Lances
Ventilated injection lances are used for filling either flat-lying or slightly inclined walls and roof elements. The lance is injected through a hole on the frame right to the end of the element. The double pipe construction ensures a good ventilation of excess air. At the lance outlet a ventilation cage is installed. Thereupon, the air is led into the dust bag (passive ventilation) or into a dust removal system (active ventilation).

Hole Saws and Closing Solutions
We offer hole saws for a multiplicity of planking materials such as OSB, gipsum boards or wood fibre boards in our product range. Our sealing corks and wood fibre closing plugs are adjusted to the hole saws.
This ,therefore, ensures a gapless closing system for blowing injection holes.
