What are the advantages and disadvantages of casement and sliding aluminum windows?

One, sliding windows:

Advantages: does not occupy indoor and outdoor space, random control of the opening area, easy to operate. Especially suitable for use in the bay window.

Disadvantages: wind pressure resistance is generally not ideal.

On stormy days, the window can only be closed and can not change the air.

Sealing is not very good, moisture, dust easy to enter. The slide under the window frame slides back and forth, with a large space on top and a gap between the pulleys on the bottom, creating a large heat loss.

Two, casement windows?

Advantages: its wind pressure resistance is better and simple, safe, flexible, easy to clean the glass on the outside of the window. Outer casement window is a traditional, simple way to open, does not take up indoor space.

The inner casement window can realize two functions of upward or downward hanging tilt open and inner casement through hardware linkage device, which can softly replace the indoor air. Generally, good rubber sealing strips are used between the window sash and the window frame, and the sealing is excellent.

Disadvantage: occupying indoor and outdoor areas. If it is a single internal casement, the hard corner of the window is easy to bruise when we are not paying attention.

Expanded information:

The inside and outside of the thermal insulating profiles, which can be profiles with different cross-sections, also Can be different surface treatment of different color profiles. But by the region, the influence of climate, to avoid the thermal insulation materials and aluminum profiles of the coefficient of linear expansion of the gap is very large, in the thermal expansion and contraction of the two produce a large stress and gap;

At the same time, the thermal insulation materials and aluminum profiles into one, in the structure of the doors and windows and curtain walls, the same and aluminum as the same force. Therefore, the requirements of the thermal insulation material must also have and aluminum alloy profile close to the tensile strength, flexural strength, expansion coefficient and modulus of elasticity, otherwise it will make the thermal insulation bridge was disconnected and destroyed. Therefore, the selection of thermal insulation materials is very important.
