Product Description

DIMEX is the first manufacturer in Europe who provides Thermal Insulating Profiles for Aluminum Windows/Doors and Facades. We continue to develop and innovate, the raw material for thermal insulating profiles from PVC to ABS, and then from ABS to better performance polyamide(PA). In order to meet the demand of high-end market for thermal barrier system windows/doors, we have also developed PE foamed insulating profiles and polyurethane (PU) foamed insulating profiles

DIMEX Taicang has been producing thermal insulating profiles since 2004Now we have more than 30 extrusion lines of thermal insulating profiles and almost 100 kinds of thermal insulating profiles are developed independently. The annual capacity can reach more than 3000 tons. Our company has a strong R&D team to produce thermal insulating profiles according to customers' requirements.


Thermal Insulating Strip for Window and Doors.

What is Thermal Insulating Strip?

Thermal insulation strip is the core component of the thermal barrier aluminum profiles. The quality of thermal insulation strips not only determines the heat insulation effect of aluminum windows/doors, but also determines the application experience of windows/doors.


What is PA66GF25 ?

PA66GF25 special composite is reinforced with glass fiber for excellent thermal insulation and is the best solution for aluminum window/door systems.

PA66 refers to its material is mainly polyamide 66(commonly known as polyamide 66 or PA66), while GF25 refers to the thermal insulating strip added with reinforcement 25% glass fiber (GF for short). The toughness and strength of thermal insulating strip is much better after adding 25% glass fiber,and the tensile strength can easily reach more than 80 MPa.

Classification of thermal insulating strips.


The shape of insulating strip can be roughly divided into: “I-shape, C- shape, T- shape, multi-chambered”, etc.


“I” shape:The strips are roughly shaped like a capital I. They are generally designed to be short (pictured above).

“C” shape:This is an updated version of the I-shape; The heat conduction path of C-shaped heat insulation strip is longer than that of type I, and the heat transfer efficiency is lower, so the heat insulation effect is better.


“T” shape:It's a little tail on top of the C-shaped insulation strip; And the role of this small section is to better realize the central rubber strip and heat insulation material lap, improve the overall profile heat insulation performance.


Multi-chambered: Multi -chambered insulating strip is another evolution in recent years. The shape of this kind of insulating strip is more complex than before and there are cavity holes inside, the energy saving of the whole window will be greatly improved.

How do you see the difference between products?

a、The wider the thermal insulating strip is, the better the heat insulation is. There is a misunderstanding: the thermal insulation effect of a window is good or poor is not necessarily proportional to the width of the window section, but is closely related to the width of the insulating strip. Compare different brands of different windows/doors, the wider the insulating strip, the better the insulation effect of the whole window.


b、It is better if the isotherm of thermal insulating strip inside the profile is the same straight line. When cold and hot air is exchanged inside and outside the window, the two broken bridges are in the same straight line, which is more conducive to the formation of an effective cold-hot bridge barrier, which can reduce the cold and hot air conduction and reduce unnecessary heat loss.
