Glazing

Types of glazing

Light permeability of the glass:

One way mirror glass has a thin layer of reflective coating which allows the glass to reflect half the light that hits it. Simultaneously, half the light also goes straight through. This makes the glass both reflective and transparent. During the day, the outside is bright which means that people who are outside are not able to see what is inside the house. However, during the night when the light is on, the one-way mirror turns into a window. People are able to see through the glass both ways.

To solve the issue, one can apply the one-way vision foil. The foil consists of hundreds of small holes enabling light penetration, which gives the effect of semi-transmission. It is usually used for advertisement on buses or windows.

Lever Handle vs T-bar Pull Handle

1. If you have a Lever handle/normal handle from the outside, you can release the latch without using a key from outside. You simply push the Lever handle down and the latch will retract allowing you to open the door.

2. If you have a T-bar long handle from the outside, it has no way to release the latch because it is only used for pushing and pulling the door. So in this situation from the outside you always need keys to re.lease the latch. Then insert the keys into the key hole and turn to release the latch and open the door.

3. We offer a third additional option if the customer decides to purchase a T-bar. When selecting the T-bar on our website, you can additionally order a Knob Handle that will be installed together with the T-bar from the outside. This door Knob Handle will allow you to release the latch from the outside. So you can order Tbar + Knob which is quite small and looks quite nice.

Multi-point lock system

• Three-dimensional locking with integrated hooks and metal pins for optimal security.

How measure the hole in the wall for door installation

The picture shows the dimensions of the door with the frame and how to measure the opening for door installation. Please take the measure from the floor "tile or wooden panel" inside the house to the top brick level.

The space for the door installation should be between minimum 5mm to 20mm larger than the overall size of the door with the frame. This space is necessary as it should be filled with foam during the installation. This will also ensure insulation between the wall and the door frame.
