Plasterboards also known as Drywall consists of materials Gyproc or Gypsum wrapped in heavy duty paper with a general width of 12.5mm which can be used in the external or internal walls and roofs of residential or commercial buildings. Insulation boards consist of a high-performance, rigid polyisocyanurate (PIR) insulation board specifically designed to reduce thermal bridging and heat loss. Insulated Plasterboard combines these two building materials into a high-quality, reliable, 2-in-1 product with a thermal conductivity of just 0.022W/mK.
PIR Insulated Plasterboard
There are multiple methods in which wall insulation boards can be installed including:
- External Wall – Masonry Cavity Internal Linings
- External Wall – Timber Frame Internal Linings
- Solid Walls – installed onto an internal wall with dot and dab or timber stud method
- Partition Walls – installed in between the timber frame of the stud wall
- Pitched Roof – installed between the internal timber rafters in the roof
- Flat Roof – installed below the timber joists
What are the benefits of PIR Insulated Plasterboards?
- PIR Insulated Plasterboards offer a 2-in-1 product which will save you time and money on you application method and products purchased.
- PIR Insulated Plasterboards improve the thermal quality of the property. This means a more temperature-controlled environments with cooler summers and warmer winters. Thermal quality means less drafts, less heat escaping the property and a more comfortable living and working spaces.
- By preventing heat and energy escaping the property you will save money on your energy bills as less energy will be needed to heat your property.
- With less heat escaping, it will have positive effect on the global warming and climate change, not only saving you money but also making your property more energy efficient and sustainable.
- Zero ODP (ozone depletion potential) Low GWP (global warming potential).
- When installed correctly, wall insulation will have a lifespan that lasts for as long as the building itself.
- PIR Insulated Plasterboards are lightweight and easy to cut, handle, and install.
- Insulated Plasterboards can be cut using either a fine-toothed saw or a sharp blade.
- Insulated Plasterboards can improve the quality of the internal wall and create a seamless finish.
- The finish applied to insulated plasterboards is optional as they can be plastered or decorated directly.
How is PIR Insulated Plasterboard installed?
Fix timber battens at the floor and ceiling around the room’s perimeter. Then fix further battens to the wall and around any openings or surfaces. Fix each batten approximately 75mm from its end and no more than 600mm horizontal centres. Start the insulation from an internal corner, a window or door reveal. Insulated plasterboard sheets should always lap the timber battens at the sheet joints. Ensure each sheet is lightly butted with fixings located no less than 10mm from the bound edges of the sheet. Cut the insulated plasterboard approximately 5mm short of the floor to ceiling height. Fix the sheet with either drywall screws at 300mm centres or large-headed galvanised clout nails at 150mm centres. Fixing should be long enough to allow a minimum penetration into the timber batten or frame.
PIR Insulated plasterboard is a high-quality board of rigid polyisocyanurate (PIR) with paper facings bonded to each side that is fixed onto a 12.5mm plasterboard. These boards have a thermal conductivity of 0.022W/mK and offer a range of different sizes to fit every installation need. Insulated plasterboard is available from brands Celotex, Kingspan, Siniat, Speedline and more.
