# Screening Types

> Understand the four screening types in Målbar LCA and when to use each one.

When creating a screening in Målbar LCA, you can assign a **Screening type** in Base Data. This tells the tool how the product is used — whether it's a finished product or a component that feeds into other screenings.

Choosing the right screening type ensures your climate footprint calculations are accurate and that components are reused correctly across your product portfolio.

## The four screening types

### Product

The default type. Use this for finished, sellable products — items that are sold directly to customers.

Examples: a chair, a lamp, a textile item.

### Product-ready component

A complete sub-product that is assembled into a finished product without further modification. It has a fixed weight and material composition.

Examples: a seat cushion, a drawer unit, a lamp shade.

<Note>
  Use this type when the component is always used in a fixed quantity and does not need to be scaled.
</Note>

### Scalable component

A component whose contribution to the final product is based on a proportion of its total weight — for example, a fabric roll where only part of it ends up in the finished product.

Examples: fabric sold by the metre, foam sold by weight, a sheet of glass cut to size.

<Note>
  Use this type when only a fraction of the component ends up in your final product.
</Note>

### Electrical component

A component that consumes electricity during its use phase. Målbar LCA applies specific use phase calculations based on power consumption.

Examples: a motor, a LED driver, a battery charging unit.

## How to set the screening type

<Steps>
  <Step title="Open Base Data">
    Click the pen icon next to your screening to open the Base Data editor.
  </Step>

  <Step title="Find the Screening type field">
    Scroll down to the **Screening type** field and select the appropriate type from the dropdown.
  </Step>

  <Step title="Save">
    Click **Update base data** to save.
  </Step>
</Steps>

<Tip>
  You can also change the screening type in **Bulk edit** — even if the screening is already being used as a component in another screening.
