GLAZED UNITS WITH WARM EDGE

ABOUT GLAZED UNITS WITH WARM EDGE

T Grup Cam‘s Glazed Units with Warm Edge technology enhances thermal insulation and energy efficiency by reducing heat loss at the edges of insulated glass units. Traditional aluminum spacers conduct heat, leading to cold bridges and increased energy consumption. Our warm edge spacers, made from high-performance insulating materials, minimize heat transfer, ensuring better thermal efficiency and reduced condensation risk.

Benefits:

✅ Improved Thermal Insulation – Reduces heat loss and enhances energy efficiency.
✅ Condensation Reduction – Minimizes moisture buildup on the glass edges.
✅ Higher Comfort Levels – Eliminates cold drafts near windows.
✅ Eco-Friendly Solution – Contributes to lower carbon emissions and sustainable construction.

ADVANTAGES

Reduction of the linear heat leakage bridge on the edges of the glass unit

Minimizes linear heat loss at the glass edges for improved insulation.

Limitation of condensation of the edges of the glass unit

Reduces edge condensation, ensuring clearer and more durable glass.

Warm edge criterion according to EN ISO 10077-1

To the time of establishing clear criteria enabling the definition of the warm edge concept, many spacer bars in glass units were sold on the market, which were indeed warmer than aluminium bars however had incomparably worse properties than correct solutions. According to this bars with improved design standard parameters are those, in which the spacer bar fulfils the following inequality:

Σ (diλi) ≤ 0,007 W/K

where:

di – thickness of partition material

λi – television of conductivity of material in W/mK

Example: 2(d1λ1) + (d2λ2) ≤ 0,007 W/K

The table below shows how particular types of bars fulfill the raised criterion:
