CN Glass Introduces Two‑Part Structural Silicone Sealant for Enhanced Performance

Structural glazing sealants are a vital component in today’s modern building systems. They allow glass to be securely bonded to other materials—whether glass‑to‑glass or glass‑to‑metal—while offering exceptional flexibility, UV resistance, and long‑term durability. These qualities make silicone sealants the preferred choice for load‑bearing applications such as curtain walling and glass façades.

At CN Glass, based in Banbury, Oxfordshire, we’re proud to announce the introduction of a two‑part structural silicone sealant into our in‑house glass processing system. This advanced sealant is applied during the final assembly stage, before each window is fitted into its frame, ensuring maximum precision and performance.

Unlike traditional one‑component sealants, a two‑part system combines two separate elements just before application:

• A base material containing silicone polymers and specialised additives
• A curing agent that reacts with the base to create a strong, reliable structural bond

This upgrade will now replace our standard sealant across all relevant projects—and for good reason.

Why the Change Matters

Our new two‑part structural sealant brings a host of benefits to both the construction industry and our customers:

• Greater strength and durability, ideal for demanding structural applications
• Improved resistance to extreme weather and UV exposure, ensuring long‑lasting performance
• Significantly reduced curing time—from approximately two days to just 12 hours—helping to minimise project downtime and keep schedules on track

A Sleek, Modern Aesthetic

Beyond its technical advantages, the two‑part sealant also supports the clean, contemporary look that architects and developers increasingly seek. By bonding glass panels directly to the structure, it enables a frameless appearance without the need for bulky metal retainers or covers. The result is a seamless finish that enhances both design freedom and visual impact.
