HANDLING AND STORAGE

Correct handling and storage of Masons Intertenancy Wall System components are

critical for best performance, ease of use and warranty adherence.

Handling

Lift Masons Enviro™ AAC panels by the long edge, carrying a panel between two

people. Unload panels as close as possible to the installation area. Use trolleys or other

mechanical devices where this is not possible.

Take care handling the panels to avoid damage to edges and surfaces.

Other products must be handled in accordance with the component product

manufacturer or supplier requirements.

Storage

Masons Enviro™ AAC panel packs must only be stacked one pack high and must be

properly supported on level ground.

Mineral wool insulation and Masons Enviro™ AAC adhesive mortar must be stored dry

and covered.

Other products must be stored in accordance with the component product manufacturer

or supplier requirements.

TOOLS AND EQUIPMENT REQUIRED

Install the Masons Intertenancy Wall System using standard carpentry tools and

equipment. a diamond-impregnated cutting blade and a sabre/reciprocating saw with

demolition blade.

Use tools in accordance with good trade practice and supplier’s instructions.

Use protective equipment when cutting panels, as Masons Enviro™ AAC panels contain

crystalline silica or silica dust. Equipment must include P1 or P2 dust masks, protective

glasses or goggles, earplugs or earmuffs, gloves, long sleeves, pants and protective footwear.

PREPARATION

Step 1: Building consent documentation

Access and view the building consent documentation.

Ensure NZS 3604:2011 and NASH Standard Part 2: May 2019 Light

Steel Framed Buildings are available for reference.

Step 2: Primary structure (excluding Masons Intertenancy Wall System)

Ensure the framing of the primary structure is straight and true

and within framing tolerances as described in section 2 and Table

2.1 of NZS 3604:2011 or section 2.5 and Appendix A of NASH

Standard Part 2: May 2019 Light Steel Framed Buildings.

Step 3: Prepare Masons Enviro™ AAC panels

Masons Enviro™ AAC panels can be cut to the required length

using power or hand tools with a diamond-impregnated cutting

blade.

INSTALLATION

Step 1: Details

Access and view the relevant Masons Intertenancy Wall System

details in the building consent documentation or from Masons

Plastabrick [link to details button].

Step 2: Install rst wall frame

The Masons Intertenancy Wall System has one wall frame on each

side of the Masons Enviro™ AAC panel.

Install one of the wall frames. Ensure the framing is straight and

true and within framing tolerances as described in section 2 and

Table 2.1 of NZS 3604:2011 or section 2.5 and Appendix A of NASH

Standard Part 2: May 2019 Light Steel Framed Buildings.

Install temporary bracing to the wall to keep the wall straight and

plumb during installation of the Masons Enviro™ AAC panels.

Check the building consent plans for any applicable building

services. Services may be run in the gap between the Masons

Enviro™ AAC panel and the framing, but the services must not

touch the panel or the brackets to ensure sound transfer is

prevented.

Penetrations are not permitted unless these are specically re

engineered.

Step 3: Install Masons Enviro™ AAC panels

Install base panel

Ensure installation allows for the 20 mm air gap to be maintained.

Check framing to ensure that any deviations from the vertical do

not reduce the size of the air gap.

Fix aluminium angle brackets, starting at one end of the wall.

Fix brackets every 3 m vertical height and at 400 mm horizontal

centres for maximum wall height of 6.6 m and every 250 mm

horizontal centres for maximum wall height of 10 m. On end studs,

install two brackets per panel.

Fix using:

› 12 g x 20 mm Hex head self drilling, Class 3 screws to steel

framing or

› 12 g x 35 mm Hex head Type 17 self drilling Class 3 screws to

timber framing.

Temporary brackets can also be installed for support during

installation, one stud back from the end of the panel at the panel

centre height.

Install C channel to the end of the wall using angle brackets.

Install C channel to the slab using a bed of Masons Enviro™ AAC

adhesive mortar on the slab or x C channel tracks using 50 mm

concrete nails at a maximum of 1200 mm centres.

Ensure the C channel is level pack with ‘H packers’ where required.

Insert panel into C channels ensuring panel is level. Fix to angle

brackets using 12 g x 45 mm Hex head SDS Type 17, Class 3

screws.

Apply a bead of re retardant sealant along the outer junction of

the base channel and the oor.

Install upper panels

Apply 2 mm–3 mm thick Masons Enviro™ AAC adhesive mortar

to the edge of the base panel. Install the next panel on top of the

base panel slotting into the C channel. Temporarily x the panel

to the frame using an angle bracket. Ensure panels are joined as

close as possible and sealed with Masons Enviro™ AAC adhesive

mortar.

Continue to install panels in a stack bond conguration.

Install H-jointer

Insert one side of H-jointer to the end of the installed stacked

panels.

Fix the H-jointer to the frame by installing aluminium angle

brackets at the top plate and bottom plate of the wall.

Install remaining stacks of panels

Install remaining stack of panels, tting panels into the C channel

and the H-jointer, ensuring panels are joined as close as possible

and sealed with Masons Enviro™ AAC adhesive mortar.

Install H-jointer between stacks and a C channel at the end of the

wall.

Step 4: Install second wall frame

Install the second wall frame. Ensure the framing is straight and

true and within framing tolerances as described in section 2 and

Table 2.1 of NZS 3604:2011 or section 2.5 and Appendix A of NASH

Standard Part 2: May 2019 Light Steel Framed Buildings.

Ensure the air gap of 20 mm has been maintained. Adjust the

framing if necessary.

Check the building consent plans for any applicable building

services. Services may be run in the gap between the Masons

Enviro™ AAC panel and the framing, but the services must not

touch the panel or the brackets to ensure sound transfer is

prevented.

Step 5: Install insulation

Install insulation in accordance with the selected insulation supplier’s

requirements. Cut to t size and install strapping where required to

ensure the insulation does not bulge out into the air void.

Step 6: Install plasterboard

Install plasterboard in accordance with the selected plasterboard

supplier’s requirements.

Check the building consent for any wall bracing requirements.

Plasterboard xing may vary depending on wall bracing or a non-

bracing design.

Step 7: Install insulation to top of wall

Install non-combustible, moisture-resistant, mineral wool insulation

to the top of the wall to ll the voids within the roof capping and

junction of the intertenancy wall.
