Technoform added a high-profile, plastic hybrid stainless steel warm-edge spacer to its Spacer M family of durable high-performance insulating glass edge seal solutions. The product is composed of high-performance engineered polymer with a thin, low-conductivity stainless steel backing to minimize heat transfer, and to maximize protection against gas leakage and moisture penetration. At 8 millimeters high with the reinforcing wire, the Spacer M high provides improved processability, particularly for the largest insulating glass units, say officials.
