The benefits of dry-lining brick walls
Central Avenue Homes offers dry-lining to internal walls in the Perth Metro region only, instead of float and white set finish as an optional item.
In short, dry-lining is the application of plasterboard directly to the internal brick or block walls. The plasterboard is fixed using a mortar based glue and applied with a recently developed applicator. There are no nail or screw holes which means the only finishing is at the recessed edge joints. The joints are the same as those in most ceilings.
Dry-lining is installed at the same time as the ceilings and is quicker than standard float and set.
- The boards are “thrown”, (installed)
- Cornices are installed
- flushed – joining tape covers the joins and finishing product covers the tape
- sanded – the finishing product is sanded
- The internal walls are ready for painting.
Apart from the increased speed of application when compared with float and set, the walls and ceilings are completed at the same time. There is no down time waiting for the availability of trades. And the house can be locked up a lot quicker.
Anecdotal evidence shows the occurrence of ‘cornice cracking’ is highly minimised if not eliminated when dry-lining b. This is essentially due to the materials being joined at the cornice are similar with cornice over plaster set walls.
Improved Acoustic and Thermal Properties
As the plasterboard is installed off the walls slightly an air gap is created (either side on internal walls). This improves dramatically the thermal and acoustic qualities of the structure. In addition the board is lifted off the floor which allows the wall to continually breathe.
Plasterboard is manufactured in a controlled environment. It is extremely consistent in respect to surface finish and straightness. So the finished product reflects those properties. The walls are generally straighter and do not show minor imperfections which is often the case with hand trowelled plaster walls.
The surface of the plasterboard is far more resilient in respect to day to day wear and tear than conventional trowelled plaster surface. Notwithstanding that feature, the plasterboard is very easy to repair if subjected to severe damage with products readily available at your local hardware store
Every external corner, including full height, door height openings and window reveals, are fitted with a metal external angle. This angle is flushed onto the plasterboard which not only provides a straight finish but also resists day to day traffic bumps and knocks.
Minimise Introduction of Moisture and Waste
There is almost no water used in the application of the plasterboard. The glue and jointing products may have minimal water. As such, there is no moisture introduced to the home. In addition, as there is no sand, cement, lime etc required, the only waste is the off cuts of the plasterboard. The off cuts are far easier to manage and dispose of than excess sand and render tailings.
The fact that little or no moisture is introduced to the walls means that painting can start almost immediately. Plastered walls often require several months to dry enough before painting can start.
Smooth Straight Finish to Window Reveals
The finish inside window and aluminium sliding door reveals is achieved by fixing plasterboard and an external metal angle trim piece around the window. This in turn, is flushed to the plasterboard. This results in a straight smooth finish all round the window. It will not chip at the joint between the window frame and the trim.
The dry-lining system has been the standard construction practice in the UK for decades. As such has withstood the test of time.
As a general rule, Central Avenue Homes offers the plasterboard dry-lining as a painted product. The reason being is that when finished the plasterboard walls are not all white (as is the case with plastered walls). Most owners prefer the painting to be done before moving in.
As the plasterboard is installed directly on the brick or block walls, it is still considered a ‘double brick’ home.
In addition, the use of plasterboard wall linings, on steel or timber framed walls is common throughout the rest of Australia. Perth is unique in its use of float and set finish for internal walls.
