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

ByBecky Butler

Quick Summary

Two-part structural silicone sealants combine a silicone polymer base with a curing agent to create strong durable bonds between glass and structural frames. Applying two-component sealant systems during assembly accelerates curing times from two days to twelve hours, significantly reducing project downtime. This advanced bonding technology delivers superior resistance to extreme weather and ultraviolet radiation. Removing bulky mechanical retainers enables structural glazing to achieve seamless frameless aesthetics. Specifying two-part structural silicone sealants from CN Glass ensures mechanical stability and high performance for commercial curtain walling.

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.

  • CN Glass Winter Home Check-List

    ByBecky Butler

    A winter home checklist for windows and doors focuses on identifying draughts, degraded seals, internal condensation, and mechanical hardware faults. Checking window and door perimeters by hand reveals unwanted cold air infiltration. Inspecting rubber seals ensures weatherstripping remains free of cracks and physical gaps. Moisture or misting between double-glazed glass panes indicates a failed sealed unit requiring replacement. Testing locks and hinges confirms doors and windows close fully to prevent thermal loss. Replacing damaged units through CN Glass restores building thermal performance and lowers winter heating expenditure.

    Reducing Operational Carbon Through Smarter Glazing Choices

    ByBecky Butler

    Smarter glazing choices reduce operational carbon by lowering thermal transmittance and minimising building energy consumption. Modern double and triple glazed units feature low-emissivity coatings, warm-edge spacer bars, and argon gas fills to retain internal heat. High-performance glass prevents thermal loss in winter while controlling solar heat gain during summer. Decreasing energy demand directly reduces active heating and cooling usage, lowering operational carbon emissions across commercial and residential properties. CN Glass manufactures bespoke low-U-value sealed units engineered to achieve long-term carbon reduction and regulatory energy compliance.

  • Is your Home Losing Heat? Ensure Your Windows are Winter Ready

    ByBecky Butler

    Windows account for up to thirty percent of residential heat loss through compromised seals, damaged frames, and failed double glazing units. Cold draughts around frame edges signify deteriorating weather stripping or faulty lock mechanisms preventing tight window closure. Condensation forming between glass panes indicates a blown sealed unit where insulating gas has escaped. Rectifying window heat loss requires repairing faulty locks, applying draught-proofing seals, or retrofitting secondary glazing to improve thermal retention. Addressing window seal failures restores energy efficiency and prevents thermal energy escaping through domestic glazing.
