Edge bond solutions –
focusing on the next level of excellence

Today, building developers are met with rising energy costs coupled with the impacts of climate change. As such, ever more focus in placed on making our buildings greener and more energy efficient.

Technoform warm edge spacer ensures good thermal insulation at the edge of glass, allowing for building energy reduction. More importantly, it is also a key passive design strategy, which allows for energy savings to be reaped over the entire lifespan of the façade.

We offer custom laser marking to include your logo or any other additional information, which will support you in your company’s branding.

If custom laser marking is not required, our warm edge spacers will be laser marked at regular intervals with Technoform, the order number and the Technoform article number. The correct manufacturer, extrusion location and product information can be easily verified, ensuring ease of identification, traceability and quality assurance.

Technoform warm edge spacers can be used across the full range of fabrication processes such as bending and cut and corner. Each of these spacers have specific features that increase productivity for IGU manufacturers while maintaining the thermal performance and durability we are known for.

For example, some of our spacers are made with more rigidity in mind, making it easier to process and handle large size spacer frame. We also have spacers designed with more flexibility, which makes it a go-to for radius shaped IGUs, such as arch-tops and circular shapes, and for bent/curved IGU.

Reference standard: EN ISO 1279
Our product performance: No fogging observed
Significance: The fogging test started out when the automotive industry begun to use more plastics in the construction of their internal components. As the car is constantly exposed to sunlight, poor quality plastics can cause emission of Volatile Organic Compounds (VOCs), which can cause contamination to the windscreen. However, for IGUs, any contamination to the inner surface of the glass surfaces facing the cavity cannot be clean as it is sealed in. Furthermore, low-e coated surfaces commonly use in the industry are more susceptible to fogging damage.

Hence, it is important that there is no emission of VOCs from our warm edge spacer. The fogging test is conducted with our warm edge spacer installed into a test IGU to evaluate off-gassing performance when exposed to an elevated temperature. 

Reference standard: EN ISO 4892-2 
Our product performance: No significant color change after 4000 h
Significance: In the application of IGU on building envelopes, there will be constant exposure to sunlight. When exposed to sunlight and in particular, UV lights, it will cause degradation to plastic compounds. 

We conduct testing to ensure minimal color degradation even after long term exposure to sunlight, such that overall aesthetics of the insulating glass will not be affected. With reference to the EN4892 test standard, we set our internal test requirement to expose our spacer to direct UV light for 4000hours, which is equivalent to 10 years of sunlight exposure.

Reference standard: EN ISO 178 
Our product performance: Rp0.2 ≥ 40N mm² reference
Significance: Warm edge spacers play a role in maintaining the structural stability of the IGU. A warm edge spacer with good mechanical performance will provide consistent support and maintain the shape of the IGU, helping to prevent it from bowing or warping over time.

Reference standard: EN ISO 1279
Our product performance: Auto Clave Min. 100N
Significance: By ensuring good adhesion between the warm edge spacer and sealant, it ensures minimize gas leakage (Argon & Krypton) as well as moisture penetration, which may lead possible condensation within the glass. This will increase the durability and performance of the insulating glass.
