Super Spacer® is the UK’s leading foam warm edge spacer bar for IGU production — combining exceptional thermal performance with manufacturing speed that no rigid spacer can match. Its flexible, foam construction means sealed units can be assembled in under 20 seconds, with no corner keys, no butyl application and no mechanical joining.
For high-volume producers, upgrading to a fully automated Super Spacer® line delivers 23.5% more units per shift using just 3 operators — compared to 9 on a traditional rigid spacer line. The net saving: approximately £180,000 per year.
Super Spacer® also offers 100% shape memory, low moisture vapour transmission and a thermal conductivity of 0.19 W/mK — meeting and exceeding the thermal requirements of Part L and Future Homes Standard compliance.
Super Spacer® TriSeal™ is Edgetech’s heavy-duty warm edge spacer bar for structural and commercial glazing applications. Where standard sealed units face elevated stress — large-format curtain wall panels, structural glazing or extreme climate conditions — TriSeal™ delivers the durability required.
Its unique triple-seal design incorporates a PIB primary sealant bead compatible with any secondary sealant, making it suitable for the full range of commercial backing sealants.
The 100% shape memory construction means the spacer returns to its original position regardless of thermal expansion or contraction — protecting edge seal integrity over the full service life of the unit. The matt black finish blends with all frame colours, and the product is available in cavity sizes from 8.2mm to 20.2mm in 2mm increments.
Contact UsDuralite® is a single-seal insulating glass spacer bar system built for cost-effective, high-volume IGU production. Applied in a single step with no corner keys required, Duralite® eliminates the mechanical joining and secondary sealing process — reducing production time and labour cost per unit.
Its composite laminate construction combines spacer, desiccant and sealant in one pre-assembled product, making it ideal for manufacturers who need a streamlined, efficient warm edge solution.
Duralite®’s low profile and flexible construction also makes it the preferred choice for conservation and heritage double glazing, where it follows the irregular surface of traditional hand-blown glass without visible corner joins.

TruPlas® is Edgetech’s rigid warm edge spacer bar — an ideal upgrade path for IGU manufacturers currently using aluminium or steel spacers. Made from glass-reinforced thermoplastic, TruPlas® runs on the same machinery as traditional rigid spacers, so there is no capital investment or line conversion required.
The result is a spacer bar with significantly lower thermal conductivity than metal alternatives, delivering improved U-values and better condensation resistance — without changing your existing production process. TruPlas® is available in standard cavity sizes and in black, white and grey to match any frame profile.
Get in touchWe’ve also been hard at work in recent months developing a new generation of spacer bar products.
Super Spacer® T-Spacer™ SG is a metal-free, silicone-based warm edge spacer made of structural foam, with an integrated desiccant that’s been designed for the toughest commercial applications.
T-Spacer SG offers enhanced shape memory, which is critical for the long-term integrity of the edge compound. Its elastic structural foam follows climate-related movements of the glass, relieving a large proportion of the load from the butyl seal.
This is a huge advantage in parts of the world that experience fluctuating temperatures.
T-Spacer SG also follows in the long-established Edgetech tradition of offering superb energy efficiency, achieving thermal conductivity of just 0.19 W/m2k.
