Insulation for Walls & Partitions
How Wall Insulation Works
Wall insulation helps reduce heat transfer through external walls and absorb sound within internal partitions. The right solution depends on the wall construction, available cavity depth and whether thermal comfort, sound control or both are the priority.
Cavitybatt and Cavitylite are purpose-made glasswool options for timber frames, steel frames and drywall systems. If you are considering Knauf Earthwool or Aerolite Soft Touch, confirm that the selected product and thickness suit your wall system and its installation requirements.
Insulating New or Existing Walls
New construction and renovation provide an opportunity to fit insulation before the wall lining is closed. For existing partitions, assess access and the condition of the wall before planning an upgrade. Choose material that fits the cavity and can be supported securely within the framing.
Compare thermal performance, fire classification and suitability for the specified wall assembly. Calculate quantities from the area to be insulated, allowing for openings and cutting waste. We can help with product selection and supply quotes for Johannesburg, Centurion and Pretoria.

Glasswool Blanket Rolls
Knauf Earthwool and Aerolite Soft Touch are blanket roll options to consider where the wall-system specification permits their use. Check the selected product, thickness and support method before ordering.
- Compare roll widths, thicknesses and coverage.
- Cut and fit according to the wall specification.
- Use the required support to maintain coverage.
A blanket selected for a ceiling is not automatically suitable for every wall. Confirm that the exact product meets the wall system’s thermal, acoustic and fire requirements.
Compare Wall ProductsWhich Thickness Do You Need?
Start with the available cavity depth and the wall-system specification. Compare product dimensions and declared thermal performance, and fit the insulation according to the manufacturer’s instructions.
For sound control, assess the complete partition construction, including its framing, linings and junction details. Sound absorption within the cavity contributes to performance; the insulation alone does not establish the wall’s sound reduction rating.
Planning Your Material Order
Measure the wall area to be insulated, accounting for door and window openings. Compare the supplied batt or roll dimensions with the framing layout and allow for cutting waste when calculating quantities.

Before You Order
-
Measure the wall area to be insulated
Multiply each wall's length by its height, then deduct doors and windows. Count each cavity once, even when it has boards on both sides.
-
Match the product to your wall system
Check the specified thickness, cavity depth and stud spacing. Use Knauf or Aerolite rolls only where specified for the wall system. Acoustic performance depends on the complete wall construction.
-
Check coverage and delivery
The calculator uses full-pack or full-roll coverage. Add a cutting allowance for your layout, then send us your quantity, delivery address and preferred delivery date.
