Thermal Insulation Strip for Sliding Windows

Thermal Insulation Strip for Sliding Windows is installed within thermally broken aluminum frame or sash profiles to create a non-metallic separation between the inner and outer aluminum sections. Jinxing, a China manufacturer and factory, produces these profiles mainly from PA66 GF25 and develops the strip geometry according to the aluminum extrusion, groove configuration, and connection structure.

Designed for Sliding Window Profiles

A sliding window does not use the same profile arrangement as a conventional hinged window. The frame usually incorporates tracks and the sash moves along the designed running section. The Thermal Insulation Strip for Sliding Windows must therefore fit within the available aluminum profile without interfering with the functional geometry of the sliding assembly.

When selecting a strip, the important dimensions include:

· Aluminum groove width and depth

· Strip width and thickness

· Locking structure

· Position within the frame or sash

· Clearance around the sliding section

· Profile assembly method

The strip specification should be confirmed against the actual aluminum extrusion before production.

Product Features

PA66 GF25 Reinforcement

The profile is made from PA66 reinforced with 25% glass fiber, providing the rigidity required to maintain its designed shape after insertion into the aluminum extrusion.

Accurate Groove Engagement

The cross-section is designed to correspond with the receiving groove, helping the strip remain properly positioned during mechanical assembly.

Stable Profile Dimensions

Controlled extrusion and calibration help maintain consistent width, thickness, and critical section dimensions along the profile.

Temperature and Aging Resistance

The material can be evaluated for thermal aging, tensile properties at specified temperatures, water resistance, and linear expansion according to the applicable technical requirements.

Frame and Sash Profile Matching

Sliding window systems may use different thermal break arrangements for the outer frame and moving sash. The required strip geometry can therefore vary between different aluminum sections within the same window system.

For example, a frame profile may require a different width or locking arrangement from a sash profile because their extrusion geometries and available installation spaces are different.

Jinxing can review the relevant aluminum sections separately to determine the appropriate thermal insulation strip for each profile.

Considerations Around the Sliding Track

The insulation strip should remain within its designated profile area and should not alter the dimensional relationship of the sliding track.

For this reason, the strip's:

position + thickness + edge geometry + insertion depth

need to be coordinated with the aluminum extrusion. Correct dimensional matching helps avoid interference with adjacent profile components during assembly.

Material Selection

Jinxing primarily uses PA66 GF25 for thermal insulation strips for sliding windows.

The glass fiber reinforcement increases the rigidity and mechanical strength of the PA66 base material. For projects with defined technical specifications, relevant material and mechanical requirements can be confirmed before production.

Inspection Points

For sliding window profiles, inspection focuses on the dimensions that affect insertion and the relationship between the strip and the aluminum extrusion.

Key checks include:

· Overall profile dimensions

· Critical groove-engaging dimensions

· Cross-sectional geometry

· Surface condition

· Tensile properties

· Hardness

· Thermal aging performance

· Linear expansion characteristics

Inspection requirements can be adjusted according to the customer's specification and applicable standards.

Standard and Customized Sections

Jinxing can produce common thermal break profiles such as I-Type, C-Type, and T-Type, as well as non-standard sections developed for specific sliding window extrusions.

Customization can cover:

How to Specify the Product

When source Thermal Insulation Strip for Sliding Windows, the aluminum extrusion is the most important reference.

Provide the following where available:

Window profile drawing → Groove dimensions → Required strip section → Material → Color → Length → Quantity

If the window system contains different frame and sash profiles, drawings for each relevant section should be supplied separately.

FAQ

Where is a thermal insulation strip installed in a sliding window?

It is installed within the thermally separated aluminum frame or sash profile. The exact position depends on the extrusion design.

Is the Thermal Insulation Strip for Sliding Windows suitable for both sliding window frames and sashes?

The strip can be developed for either type of aluminum section, but the required geometry may differ between the frame and sash.

What material does Jinxing use?

Jinxing primarily uses PA66 GF25, with 25% glass fiber reinforcement.

Will the thermal strip affect the sliding track?

The strip should be designed to remain within its specified profile area and maintain the required dimensions around the track. The aluminum extrusion drawing should therefore be checked before selecting the strip.

Can Jinxing produce a strip for a proprietary sliding window profile?

Yes. Jinxing can develop a custom section according to an aluminum extrusion drawing or existing sample.

Can different strip specifications be used in one sliding window system?

Yes. Different aluminum frame and sash extrusions may require different strip dimensions or cross-sectional designs.
