It is suitable for internal walls, roof linings, pitched roof applications, reveals and refurbishment work, but final insulation performance depends on the board thickness, full build-up, fixing method and installation quality.\u003c\/p\u003e\n\n\u003ch2\u003eWhat is this used for?\u003c\/h2\u003e\n\u003cp\u003ePIR insulated plasterboard combines a plasterboard face with rigid PIR insulation in one board. It is designed for internal dry lining projects where you want to add insulation and create a plasterboard surface ready for finishing.\u003c\/p\u003e\n\n\u003cp\u003eTypical uses include internal walls, cold walls, roof linings, pitched roof applications, loft conversions, window and door reveals, energy-efficiency upgrades and refurbishment projects.\u003c\/p\u003e\n\n\u003ch2\u003eIs this the right plasterboard for your project?\u003c\/h2\u003e\n\u003cp\u003eChoose PIR insulated plasterboard where you need to improve thermal performance without building a separate insulation layer and plasterboard layer. It can be a practical option where space matters, because the insulation and plasterboard are combined into one board.\u003c\/p\u003e\n\n\u003cp\u003eThis board helps improve thermal performance, but it should not be treated as a guaranteed insulation result by itself. The final performance depends on the thickness chosen, the wall or roof build-up, the background, fixing method, joints, gaps, thermal bridging and workmanship.\u003c\/p\u003e\n\n\u003cp\u003eThe product page states that this board can help support Part L building regulation compliance. However, compliance depends on the full specification, installation and building requirements, not just the board on its own.\u003c\/p\u003e\n\n\u003ch2\u003eWhich thickness should you choose?\u003c\/h2\u003e\n\u003cp\u003eThese boards are available in 37.5mm, 52.5mm, 62.5mm and 72.5mm thicknesses. Thicker boards generally provide better insulation, but they also take up more room inside the space.\u003c\/p\u003e\n\n\u003cp\u003eBefore ordering, check how much insulation depth you need, how much room you can afford to lose, and whether your project has a specific thermal requirement. If a U-value or building regulation target must be met, the full build-up should be checked before choosing the board thickness.\u003c\/p\u003e\n\n\u003ch2\u003eWhat does PIR backed mean?\u003c\/h2\u003e\n\u003cp\u003ePIR backed plasterboard has rigid PIR insulation bonded to the back of the plasterboard. PIR is commonly used where good thermal performance is needed without using excessive thickness.\u003c\/p\u003e\n\n\u003cp\u003eThis product has a 12.5mm tapered edge gypsum plasterboard front face, a PIR rigid insulation core and a kraft paper rear face with aluminium foil backing.\u003c\/p\u003e\n\n\u003ch2\u003eWhat does tapered edge mean?\u003c\/h2\u003e\n\u003cp\u003eThe plasterboard face has tapered long edges. This creates space for jointing tape and jointing compound, making the board suitable for tape-and-joint finishing.\u003c\/p\u003e\n\n\u003cp\u003eIt can also be skimmed if required, but tapered edge boards are especially useful where the joints are being taped and filled rather than the whole surface being fully skim plastered.\u003c\/p\u003e\n\n\u003ch2\u003eKey features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePIR insulation backing:\u003c\/strong\u003e Helps improve the thermal performance of internal walls, roof linings and dry lining projects.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlasterboard and insulation in one board:\u003c\/strong\u003e Reduces the need for separate insulation and plasterboard layers in suitable applications.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMultiple thicknesses available:\u003c\/strong\u003e Choose from 37.5mm, 52.5mm, 62.5mm and 72.5mm depending on the project requirement and available space.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapered edge plasterboard face:\u003c\/strong\u003e Suitable for tape-and-joint finishing and can also be skimmed if required.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFoil-backed rear face:\u003c\/strong\u003e Designed to support thermal efficiency as part of the board construction.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSuitable fixing methods:\u003c\/strong\u003e The product page states that the boards can be installed using dot and dab adhesive systems or mechanical fixings.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eThings to check before ordering\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness:\u003c\/strong\u003e Thicker insulated plasterboard usually improves insulation performance, but reduces internal room space.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThermal target:\u003c\/strong\u003e If you need to meet a specific U-value or Part L requirement, check the full wall or roof specification before ordering.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation method:\u003c\/strong\u003e Confirm whether the board will be fixed using dot and dab adhesive, mechanical fixings or another specified system.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal use:\u003c\/strong\u003e This product is for internal dry lining applications, not external use or areas exposed to direct water.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMoisture exposure:\u003c\/strong\u003e Do not use insulated plasterboard where it will be in direct or continuous contact with water.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStructural use:\u003c\/strong\u003e This is not a standalone structural board.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFixings and finishing:\u003c\/strong\u003e Make sure you have suitable \u003ca href=\"\/collections\/drywall-screws\"\u003edrywall screws\u003c\/a\u003e, fixings, jointing materials and finishing products for the installation method.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStorage:\u003c\/strong\u003e Store boards flat, dry and protected before installation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eComplete the job\u003c\/h2\u003e\n\u003cp\u003eFor fixing PIR insulated plasterboard, you may need suitable \u003ca href=\"\/collections\/drywall-screws\"\u003edrywall screws\u003c\/a\u003e or mechanical fixings depending on the background and installation method.
