Conduction

Heat conduction is the non-uniform heat transfer phenomenon that occurs in a heated solid. In the case of aluminum windows and curtain walls, they account for 50% of the heat loss of the entire frame and are caused by the phenomenon of heat flowing from high temperature to low temperature through the aluminum material. In order to prevent this phenomenon and realize excellent insulation performance, PA66GF25 insulation bars are applied to sections where heat loss (flow) occurs, or by applying PA66GF25 insulation bars optimized for aluminum profile design such as shape, the heat conduction rate is lowered and the heat is reduced at the same time. Block losses. Low levels of heat loss and flow are important factors in improving the thermal insulation performance of aluminum products.

Air Convection

Thermal convection phenomenon is one of the three elements of heat transfer and is one of the heat transfer phenomena caused by the relative displacement of fluid particles. In the case of an aluminum frame with an insulating bar applied, an empty layer is created between the inside and the outside by applying the insulating bar. Heat transfer occurs through this empty layer. By supporting design improvements that divide the air layer through CT-type insulation bars and various hollow-shaped thermal insulation materials, heat loss due to convection can be prevented.

A variety of design solutions

Various design solutions Through multi-hole and wide width of thermal insulation materials, heat loss due to convection and conduction is effectively blocked, supporting a high-insulation solution for aluminum frames

Kronos PA66GF25 Blade Solution

A high level of insulation can be achieved through various design combinations. Insulation performance can be improved by improving the design of the PA66GF25 insulation strip and applying various shapes and design. By applying PA66GF25 insulation strip, air layers can be minimized and heat transfer effects can be improved. In addition, additional insulation performance improvement and cost reduction effects are created by applying PA66GF25 insulation bars of various designs and adjusting insulation lines.

The insertable blade solution combines perfectly with the KRONOS PA66GF25 insulating bar and prevents convection and heat loss through blades of various heights. Through the KRONOS Blade solution, various designs of aluminum products can be realized, and cost savings such as additional development costs can be achieved

KRONOS' Anti-Bi Metal PA66GF25 insulating strip solution offsets the load applied due to aluminum deformation, solving the problem of Bi-Metal quality defects. Depending on the design and material combination of aluminum windows, the Bi-Metal phenomenon occurs. (Phenomena where PA66GF25 insulation bar bends due to extreme temperature difference between inside and outside) If the external frame is changed or extended, unexpected problems may occur, such as deformation of the window, deterioration of airtightness, and opening/closing (locking) problems. In order to solve this bi-metal phenomenon, KRONOS developed a vertical PA66GF25 design solution that prevents thermal expansion and contraction, called the “bimetallic effect.”
