Specification :

Strong toughness nylon block and buckle connection between the aluminum and the wood frame works, which has great connecting strength, great aging resistant strength. It not only guarantees the perfect connection of the two kinds of different retractility wood, but also completely protects the wood. When joint them together, one side of the block and buckle blocker is fastened on the wood frame work, and the aluminum frame work is fastened on the wood frame work. Then rotate the block and buckle blocker. The other side of the block and buckle blocker is rotated into the groove of the aluminum frame work to join the aluminum and the wood together. Every 100mm space there is a block and buckle blocker on the window to guarantee the connection strength. The gap between the wood and the aluminum is sealed with sealed glue, which makes its heat preservation, airproof and water proof properties more superior.

The utilization of one hollow type aluminum frame work structure of the aluminum, the triple glazing hollow glass and the quadruple adhesive tape makes the room temperature 3 ^ 5 higher than that of using other common windows at the same condition. Through measurement and test, the heat preservation property has reached the target of 1.73W/ ( ¡ • K) . According to the national standard GB/ T8484-2002, its heat preservation property has reached 9-level.
