Which One is Better? (2026 Comparison Guide)

One of the most frequently asked questions in flooring applications: Is perlite screed or classic (normal) screed better?

The answer depends on the intended use. Let's compare them in detail:

1. Weight Comparison

Perlite Screed

• 5–7 times lighter
• Does not add extra load to the building
• Contributes to earthquake resistance

Normal Screed

• It is heavy
• Adds load to the structure

Result: Perlite screed is far ahead in terms of lightness.

2. Thermal Insulation

Perlite Screed

• Provides high thermal insulation
• Ensures energy savings

Normal Screed

• Has no insulation properties

Result: Perlite screed wins in thermal insulation.

3. Sound Insulation

Perlite Screed

• Reduces impact and airborne noise

Normal Screed

• Does not provide sound insulation

Result: Perlite screed for acoustic comfort.

🔥 4. Fire Resistance

Perlite Screed

• Class A1 non-combustible

Normal Screed

• Non-combustible but insulation performance is low
