Double Sided Security Glazing Tape

Double Seal Tape Company is a manufacturer of Double Sided Security Glazing Tape for anti-removal glass fixing, double-sided holding, and window frame sealing. This tape is made for glass-to-frame contact areas where ordinary foam weatherstrip is not enough. It helps secure externally glazed windows, sash window glazing bars, interior glass panels, and tamper-resistant window assemblies while supporting water, air, dust, and draught sealing under controlled 20-30 percent foam compression.

Product Overview

Double Sided Security Glazing Tape is applied between glass, sash rebates, glazing bars, and window frames to create a continuous double-sided bond line. Instead of only filling a gap, the tape helps connect the glass unit with the rebate, frame, or bar surface, making exterior glass removal more difficult when the window system is correctly designed. It is suitable for exterior glazing, interior glass fixing, sash window repair, and applied glazing bar installation.

Foam selection should match the glazing gap and the holding requirement. High-density PVC foam is often selected where firmer support, cleaner sightline control, and better resistance to cutting or penetration are needed. Closed-cell PE foam is better suited to applications where cushioning, flexible compression, and light water or air sealing are more important. Typical foam density can be selected from 120 kg/m3 to 350 kg/m3, depending on sash gap size, frame profile, compression feel, and security requirement.

The acrylic adhesive is coated on both sides so the tape can grip both the glass side and the frame or glazing bar side during installation. Typical 180-degree peel adhesion after 24h dwell can reach 12-18 N/25 mm on clean glass or aluminium. Painted frames, aged PVC, powder-coated aluminium, and timber coatings may show different bonding results, so a 24-72h sample holding check is recommended before batch installation.

This product should be specified as a security glazing seal tape and holding aid. It is not a packaging tape, not a loose rubber gasket, and not the primary structural load-bearing adhesive for curtain wall or heavy glass systems. For outdoor glazing, adhesive aging should be checked together with UV exposure, humidity, temperature cycling, frame movement, and surface contamination.

Benefits

• Helps improve anti-removal glass fixing in externally glazed windows.
• Creates a continuous glass-to-frame bond line instead of loose spot holding.
• Supports water, air, dust, and draught sealing when the foam is compressed evenly.
• Allows 20-30 percent compression to maintain sealing contact without over-crushing the foam.
• High-density foam helps reduce glass movement and vibration at the rebate.
• Acrylic adhesive gives stable holding after 24-72h dwell on clean glass, aluminium, PVC, timber, and painted frames.
• Black foam helps create a neat sightline for dark window frames and glazing bars.
• Stable release liner supports accurate positioning before final pressure is applied.
• Slit width can be matched to narrow glazing channels, sash rebates, and bar profiles.
• Clear application limits help prevent misuse as a primary structural glazing adhesive.

What makes double sided security glazing tape different from ordinary foam sealing tape?

Ordinary foam sealing tape mainly fills gaps and blocks draughts. Double sided security glazing tape works differently because both adhesive faces are used to hold the glass and frame together. In externally glazed windows, this continuous bond line helps make the glass unit harder to remove from the outside. The foam also needs controlled compression recovery, not just softness. A 20-30 percent compression range is commonly used to maintain sealing contact, reduce air leakage, and avoid adhesive squeeze-out along the visible sightline.

Applications

• Externally glazed windows requiring stronger glass-to-frame holding.
• Interior glass panels where clean double-sided bonding is needed.
• Sash window glass fixing and rebate sealing.
• Security glazing bars applied to glass surfaces.
• Georgian bars, astragal bars, and decorative bar bonding.
• Aluminium, PVC, timber, and painted frame window fabrication.
• Shopfront glass edge sealing where controlled compression is required.
• Window repair projects replacing loose tape or unstable wet adhesive areas.
• Glass-to-frame sealing where water and air leakage must be reduced.
• Tamper-resistant window glazing projects with sample validation before batch installation.

How should the frame surface be prepared before applying security glazing seal tape?

The glass edge, sash rebate, glazing bar, and frame surface should be clean, dry, and free from oil, dust, old sealant, loose paint, cutting powder, and moisture. A contaminated surface may reduce initial tack and weaken adhesive aging performance. The tape should be placed straight and should not be stretched around corners. Heavy overlap at the corner can create uneven thickness, sealing gaps, or visible lifting after compression. After positioning, apply firm pressure along the full tape path so both adhesive faces wet out correctly.

FAQ

1. Is Double Sided Security Glazing Tape the same as ordinary weatherstrip?

No. Ordinary weatherstrip mainly seals gaps, while this tape provides double-sided glass-to-frame holding and sealing.

2. Can it stop glass from being removed from the outside?

It can help make exterior glass removal more difficult when used with a correctly designed glazing system.

3. Can it be used on sash windows and glazing bars?

Yes. It is suitable for sash window glazing, security glazing bars, Georgian bars, and astragal bar bonding.

4. Is it a primary structural adhesive?

No. It is a security fixing and sealing tape, not the main load-bearing adhesive for structural glazing.
