Heat preservation and energy saving of single point handle

Plastic steel doors and windows are multi cavity structure, with good thermal insulation performance, and their thermal conductivity is very small, only 1 / 357 of steel and 1 / 250 of aluminum. It can be seen that the thermal insulation and thermal insulation effect of plastic doors and windows is remarkable, especially for modern buildings with heating and air conditioning equipment. The results show that the indoor temperature of rooms with plastic steel doors and windows is 4-5 degrees higher than that of rooms with wood doors and windows in winter; The effect of double glazing is better in the north. According to the test of Institute of physics, the heat transfer coefficient of single glass steel and aluminum window is 64W / m2k; The heat transfer coefficient of single glass plastic steel window is about 47w / m2k; The heat transfer coefficient of ordinary double glass reinforced plastic and aluminum windows is 3. About 7W / m2k; The heat transfer coefficient of double glass plastic steel window is about 2. 5W/M2K。 Doors and windows account for 30% of the building envelope area, and their heat dissipation accounts for 49%. Therefore, plastic steel windows have good energy saving benefits.

Single point handle introduces the causes and prevention measures of hardware parts damage

Generally, the damage of hardware parts of plastic doors and windows is as follows: the hardware parts are not fixed firmly, loose and fall off, the pulley and sliding hinge are damaged, and the opening and closing are not flexible.

Causes of hardware damage:

Improper selection of hardware accessories, poor quality; There is no metal lining plate when fastening, and there is not enough installation strength.

Measures to prevent hardware damage:

(1) The sliding support hinge shall not be made of aluminum alloy, but stainless steel.

(2) Double pulleys or rolling pulleys should be set for sliding windows over 1m in width or doors and windows with double glazing.

(3) The hardware fittings should be installed at last, and the door and window locks and handles should be assembled after the window and door leaves enter the frame to ensure the correct position and flexible switch.

(4) The model, specification and performance of the selected hardware accessories shall comply with the current national standards and relevant regulations, and match with the selected plastic doors and windows.

(5) Pay attention to the maintenance of hardware after installation to prevent rust and corrosion. In daily use, it should be opened and closed gently to prevent damage caused by hard opening and hard closing.

(6) When installing hardware with fastening screws, a metal lining plate must be set inside, and the thickness of the lining plate shall be at least twice of the fastener pitch. It shall not be fastened on the plastic profile and non-metallic lining shall not be used.
