FAQ

1. What mortar or adhesive should I use?

• Standard 1 : 4 cement-sand mortar works well, or use thin-joint aircrete adhesive for faster build rates.

2. What is its compressive strength?

• Rated at 3.6 N/mm², suitable for load-bearing and non-load-bearing walls.

3. What is the thermal conductivity?

• Around 0.16 W/m·K, giving better performance than a star performer or solid aggregate block.

4. How many blocks per square metre?

• 10 blocks/m², based on the standard face size and mortar joints.

5. Where can I use Toplite blocks?

• External and internal walls, suspended beam and block floors. Not recommended for bellow damp course.

6. How do I cut or trim them on site?

• Easily cut with a powered or hand held masonary saw.

7. What fixings work best with aircrete blocks?

• Use aerated-block wall plugs (e.g., Fischer UX) or suitable resin anchors to ensure secure attachments.
