What is a deflection head?
A Deflection Head is utilised to allow for movement (up, down, or both) within the structure at the head of the partition. This movement (or deflection) is created by live and dead loads on the floor or roof above.
What is deflection in drywall?
The bending of joists, trusses, or rafters that occurs when a structure is overloaded is known as Deflection. Deflection movement causes a variety of interior building consequences. Deflection usually results in unattractive cracks in the drywall along the inside corners of the wall where it meets the ceiling, or along the filled out joints between the boards.
Where can I find deflection heads?
Here at Drywall Pro-cut, on line we sell BG/Siniat/Knauf Deflection Heads made in full. That is, we cut the board strips ( usually, Glasroc or plasterboard ) and screw them at the correct screw-centres to the metal head channel for you ( 50mm, 70mm metal etc whatever is your specification ) in whatever lengths you choose. We can also fix the fire strip onto the metal channel as well to your requirement. This saves so much time and money on site, ensures quality and your adherence to the specification.
We can also simply cut the board strips to length and width for you to fix yourselves on site. However, we firmly believe the more work we can do away from the site the better for that site!
What is plasterboard made from?
Plasterboard is basically an inner layer of gypsum sandwiched between two outer layers of lining paper. Gypsum is made up of crystals containing a small amount of water (known as water of crystallisation).
Are drywall and plasterboard the same thing?
Yes. Drywall is also known as plasterboard, wallboard, sheet rock, gypsum board, buster board, custard board, or gypsum panel.
What is the best way to cut plasterboard?
In our opinion, wherever possible, by using machinery in a factory controlled environment and then delivering it to site.
However, if you must cut on site the best technique to cut plasterboard in a straight line is to draw a line with a pencil first, then place a spirit level or other metal straight edge on top of it. While scoring along the line with a sharp craft knife, keeping the straight edge firmly in place.
