End Cover TS94–PLUS

The ALAKS TS94 Plus Interlock Cover Cap is a precision‑engineered component designed to close the profile gap in sliding interlock systems. Mounted accurately on the sash seated within the frame, it completely seals air channels, preventing dust ingress, wind noise, and airflow. Its optimized “Plus” design enhances airtight sealing, ensures smoother sash movement, and eliminates whistling sounds during strong winds.

This product has only one variant.

Description

Alaks TS94 Plus Sliding End Cap | Seal for TS94 Sliding System

The Interlock Plus End Cap, specifically designed for the TS94 sliding system, is a component whose role in the final performance of the structure goes far beyond a simple cap. This part is designed to seal all air channels and internal cavities of the Interlock profile to ensure the sliding assembly is fully insulated against air infiltration, dust, and wind noise. The “Plus” version, compared to regular models, features a larger contact surface, higher filling volume, and more precise geometry; thus, no empty space remains in the Interlock, and air pathways are completely blocked.

Why is this cap essential for TS94?

The TS94 system, due to the relatively deep section of its Interlock, faces the following issues when assembled without the appropriate end cap:

• Occurrence of whistling wind noise at medium to high speeds

• Infiltration of dust through the empty channels of the Interlock

• Increased sash looseness during movement

• Reduced vertical stability of the sash on the track

• Transmission of noise into the building due to airflow

The Interlock Plus End Cap, thanks to its engineered design, completely eliminates these problems and brings the system closer to European standards.

Technical and engineering performance of the part:

1. Complete filling of the Interlock volume:

The protruding surfaces inside the cap close all empty internal spaces of the Interlock and prevent air movement.

2. Prevention of wind noise:

In sliding systems, even the slightest gap causes the profile to whistle.

The “Plus” version, by:

• Increasing the contact surface

• Volumetric filling

• And precise positioning in the Interlock axis

Completely eliminates wind noise.

3. Improved sash movement and reduced looseness:

This part is installed on the sash positioned on the frame and, by providing a stable lateral surface, prevents the sash from wobbling sideways.

The result is a smoother, vibration-free, and silent movement on the track.

4. Prevention of energy loss and air infiltration:

Blocking air pathways increases the system’s air impermeability coefficient and reduces cooling/heating energy loss.

5. Increased lifespan of hardware:

When the sash moves without vibration and looseness, less stress is exerted on the:

• Rollers

• Track

• Lock and latch

And the lifespan of the entire assembly is extended.

Installation method of the Interlock Plus End Cap:

This end cap is installed on the sash positioned on the frame, and a 3.9 mm self-tapping screw is used for its complete fixation. The 3.9 self-tapping screw, due to its drilling tip, fastens directly into the aluminum profile without the need for pre-drilling and completely secures the cap in place. This mounting method prevents the part from dislodging due to continuous sash movement or wind-induced vibration.

Key Features:

• Plus design with complete filling of TS94 profile channels

• Complete elimination of whistling wind noise at high speeds

• Prevention of air, dust, and insect infiltration

• Reduced sash looseness and smoother movement on the track

• Precise fit with controlled tolerance

• Quick installation on the sash positioned on the frame without special tools

• Compatible with sliding window sealing standards

Applications of TS94 Plus Sliding End Cap:

• Aluminum sliding doors and windows in the TS94 system

• Structures facing open spaces or windy areas

• Luxury projects requiring silent operation

• Buildings with energy-saving requirements

The Interlock Plus TS94 End Cap is an engineered part that completes the sealing and wind noise isolation in sliding systems. This part, installed on the sash positioned on the frame, covers all open Interlock channels and, thanks to its “Plus” design, completely fills the empty space of the section. As a result, air infiltration, dust, and whistling wind noise are eliminated, and the sash movement on the track becomes completely smooth, silent, and without any looseness. In the implementation of thermal break sliding window systems, the use of standard hardware and high-quality supplementary components is not an option but a professional necessity.
