  • Superior reduction of CO² emissions and optimal energy saving.
Multitech G Bendable Spacer

Now available in the UK

The distinctive product has been proven in the European sector for the past 3 years and is now available in the UK and Ireland.

Now you see it..

Proprietary spacer systems that use aluminized aluminium tape give single and double seal IG manufacturers like you an ongoing production headache.

Tolerances on placing aluminized foil onto the spacer means a gap of up to 3.5mm on the shoulder and this in conjunction with inconsistent PIB application means your customers often see an exposed silver foil on the side of the spacer bar shoulder.

Now you don’t

Multitech G® uses a clear SIOX gas/ MVTR barrier that eliminates the cosmetic problem. All you see is the colour of the secondary sealant/PIB along the shoulder of the spacer bar.

Better looking units 1st time every time.

Triple IG-unit 4/12/4/12/4 con Ug = 0,7 W /m 2 k – ψ values in W/mk

Perforation

The popularity of hot melt single and dual sealed units enables spacer bar manufacturers to optimise product features that are not detrimental to overall product performance to all other systems but can be particularly suited to specific construction methods.

Twin lines of perforations are preferable for hot melt IG unit construction as they ensure expanding air within the spacer during hot melt application can easily pass freely into the cavity airspace and back again as the unit cools.

The desiccant has the opportunity to work straight away unlike spacer tubes with a single row of perforations that can take many weeks to absorb moisture trapped in the air space during manufacture.

Typically single breather hole systems ensure the hot air inside the spacer as it expands is forced out through a corner joint creating a leak path for moisture and gas as the breather holes are too small or few in number to be effective.
