Cutting 12.5mm Knauf Plasterboard Wallboard
If you have the correct equipment, cutting plasterboard doesn’t have to be a difficult task. Firstly measure what you need to cut. We advise using a straight edge to guide your cuts along with a sharp knife or hand saw. Use a knife or hand saw to score the plasterboard. The plasterboard can then be snapped along the scored line.

Question: | Can you double up plasterboard with insulation? |
maxfrommarble |
Answer: | Yes you can double up plasterboard with insulation to increase thermal conductivity helping further insulate your dedicated room. Remember to seek advice from a building professional beforehand. | |
Question: | What plasterboard thickness do I need? |
maxfrommarble |
Answer: | The thickness is dependent on your requirements. 12.5mm is a popular thickness, however we advise consulting an architect or building professional before buying plasterboard. | |
Question: | What is wallboard? |
maxfrommarble |
Answer: | Wallboard is another term for 'standard plasterboard'. This is plasterboard that does not offer specialist protection. For example plasterboard with water resistant properties may be referred to as moisture board rather than wallboard. The term wallboard tends to be for use in standard function plasterboards - which are some of the most common types used. This 12.5mm Knauf Plasterboard is a highly popular standard wallboard. |
