The sub-layer is the second layer of the wall and acts as a barrier to block sunlight. Here are some great sub-layer design ideas for you .

bar design

As the name suggests, this second wall layer design has a grid pattern. To achieve this design, you can use a series of trees placed vertically or horizontally.

Also, place these boards relatively close together. One of the advantages of this mesh design is that it makes the house appear taller.

Curtain Design

On the other hand, if you apply a vertical grid design to the second floor, the wooden blind design will be placed horizontally. This curtain design can also give the effect of making the house look wider and more spacious.

Generally, wooden blinds can be rolled up to block out sunlight and rain. On the other hand, this curtain design layer cannot be rolled up. Compared to using wooden blinds, using a second layer in your home can give a more attractive appearance impression.

Stacked design

To create a dynamic second layer design, you can combine multiple layers of lattice or curtain designs. Place the designs above and below with one layer facing forward. This will make the house picket look less monotonous.

Embossing design

If you’re feeling bored with designs made up of only straight lines, you can use optional patterns to create a unique design on the second wall.

To create this design, ask your carpenter to cut a large piece of wood with a unique pattern. The pattern can be as varied as you like. It can be square, circular, floral, or any other irregular  shape you like.

Later, sunlight will enter through the gaps in the pattern you created, and the incoming light will reflect on the floor and walls according to the pattern. This will make the space behind the second layer of wall look even more beautiful.

wood panel design

If you want a simple concept for a second skin, you can use this design with wood panels. To create this look, simply arrange the wood planks in a parallel and consistent manner.

All you need to do is install a pivot on several wooden boards to let in sunlight. The angle of the wooden boards can be adjusted as needed, so choose the right angle where the sunlight comes in but it is not too hot.

Open-closed design

The open and closed design of the second layer allows for control of the intensity of light and air coming in. The second layer of the wall looks like a door with a hinge on one side of the wooden planks.

Folding design

As the name suggests, this second layer of wall is designed like a folding door. The practical design allows you to make the most of the opening when needed.

Slide Design

Second layers are not only for multi-story homes, single-story homes can also have a second layer of wall to block out sunlight. Instead of installing a canopy, installing a second layer of wall can make your home look more attractive.

This type of sliding design is very convenient in a one-story home. This floor can act as not only a second wall, but also a second door into the home.

In fact, it is still difficult to find a single-story house with a second wall like this, but it is possible to try, especially if the house has large windows.

The use of secondary skin is becoming more and more necessary these days. In addition, as the temperature of the earth rises, the sunlight reaching the earth becomes hotter and hotter. Not to mention the harsh climate change.
