Material sourcing guide

AAC blocks for coordinated wall packages

Use this guide to request AAC blocks as a distinct wall package rather than a generic masonry line. Define the wall zone, block format, adhesive or mortar interface and the project-prescribed performance so suppliers can respond with a measured, comparable offer.

01 / Materials & uses

Start with the right material groups.

Wall blocks by application

Separate internal partitions, external leaves and infill walls. State the wall schedule reference and restrict the request to AAC blocks supplied for that location.

Adhesive and mortar interface

Describe the jointing material and required bed thickness as a separate interface item. Do not hide thin-bed adhesive inside a per-square-metre block rate.

Accessory and connection pieces

List lintels, U-shells, fixing plates, edge profiles and any connection material needed at floor, roof or opening junctions for the same package.

02 / Package boundaries

A material price is only part of the package.

Your material schedule
01Wall blocks by application
02Adhesive and mortar interface
03Accessory and connection pieces

One schedule, clearly separated scopes. This is a request outline, not an installation drawing.

Included materials

AAC blocks supplied to named wall locations with dimensions, density class and strength or performance requirement taken from the approved wall schedule.

Connections & interfaces

Adhesive, mortar, lintels, U-shells and connection pieces that the project places inside the AAC block package.

Confirm separately

Separately confirmed scope for substrate preparation, supporting structure, access, cranage, installation and any surface treatment outside the block supply.

03 / A comparable request

Six details that make offers clearer.

Product designation and wall schedule
State the exact AAC block product designation, wall schedule code and any project-prescribed size or strength requirement.
Block format and dimensions
List length, height and thickness by wall zone. Confirm whether plain or profiled ends and grip holes are required.
Density and mass requirement
Provide the density class or mass requirement from the project specification. Ask the supplier to identify the product data used.
Jointing and bedding material
Describe the jointing material, application thickness and whether the supplier includes adhesive or mortar in the block offer.
Wall zone and exposure
Identify internal, external or below-ground use so the supplier can connect the block choice with the approved project requirement.
Allowances and quantity basis
Separate net measured block area from cutting and waste allowance. State the measurement basis for each wall zone.

Example quantities only; no live prices or supplier offers. Use your project schedule for final values and ask suppliers to list deviations.

04 / Compare the whole offer

Three checks before you decide.

Adhesive scope in the block rate

Check whether the supplier quotation includes thin-bed adhesive or mortar, or measures the jointing material as a separate supply item.

Wall zone matching

Compare block thickness, density and intended use against the wall schedule so internal and external lines are not treated as interchangeable.

Lintel and accessory completeness

Align lintel quantities dimensions and connection accessories with the opening and junction details before comparing offers.

05 / Practical questions

Details worth clarifying early.

How should AAC block quotations be measured?

Request net wall area per wall zone and keep cutting allowance separate. This lets suppliers show the same quantity basis for each block format and thickness.

What belongs in the AAC package beyond blocks?

Adhesive mortar lintels and connection pieces can belong to the same package. State each item with its unit so the offer does not mix them into one area rate.
