The triple seal system Super Spacer® TriSeal™ Premium Plus meets the most stringent commercial requirements including Structural Sealant Glazing (SSG).


• Silicone foam

• Two-sided acrylic adhesive allows immediate handling of the units

• Polyisobutylene seal provides improved gas and water vapour tightness

• Outer silicone seal for proven structural glazing application, polyurethane or polysulfide sealants for all other applications


These flexible spacers made of silicone foam are designed in particular for simple manual processing of large format insulating glass and facade glass. The polyisobutylene (PIB) seal for substantial reduction of the gas loss rate and vapour diffusion is applied beforehand in the factory. The basic components of the triple seal system Super Spacer® TriSeal™ Premium Plus are the Super Spacer® T-Spacer™ Premium and Super Spacer® T-Spacer™ Premium Plus. Structural Sealant Glazing requires UV-stable silicone sealing.



Thermal conductivity: λ=0.15 W/mK with PIB primary seal (tested in accordance with EN 12667, IFT WA 17/1)

• Gas/Moisture vapour barrier: WVTR and oxygen transmission rate below measurable limit

• Primary structure seal: Acrylic adhesive 

• Temperature range: -40 °C to +121 °C

• Colours: black and grey (other colours on request)

• Passive House phA certificate for Arctic climate

• North America ASTM E2188/E2189/E2190

• Europe EN 1279



• Low thermal conductivity

• Fast dew point drop

• Durable edge seal, continuous vapour barrier at corners

• Breathable, flexible foam matrix

• High desiccant content absorbs moisture

• No chemical fogging

• Pleasing aesthetic appearance

• High-quality silicone for superior resistance to ozone, UV light and oxidation

• Very good gas-loss rate values according to EN 1279-3

• Optimum values for energy efficiency (ψ-values up to 0.033*)

• Enhanced comfort and well-being near windows

• Excellent condensation resistance, shape retention and colour stability

• Excellent durability for sustainable performance

• Higher productivity through ease of processing (only three process steps)

* Super Spacer® TriSeal™ / T-Spacer™ Premium Plus from structural foam processed in triple-pane insulating glass; source: Bundesverband Flachglas e.v. (German flat glass association). 



• Fast, straightforward application with more accurate corner formation

• No bubbling on the surface

• No additional filling with desiccant

• No corner brackets required

• Simplified production of shaped panes

• No butyl extrusion in a separate work step

• Immediate handling of the units

• No need to wait for the curing process

• Increase in production with a reduced workforce
