Unilin Thin-R XT/TL 2400mm by 1200mm insulated plasterboards are a rigid panel that combine a PIR insulation board with a sheet of 12.5mm tapered edge (TE) plasterboard (drywall) offering both a finishing product for the walls and thermal insulation. These boards are used within renovation and building projects to enhance energy efficiency whilst providing a smooth finish prepared for finishing products such as plaster and paint. This 2-in-1 product will reduce the time spent on installing each product separately. You can also reduce the amount spent when purchasing the insulation and plasterboard independently.

Unilin insulated PIR plasterboards will reduce heat loss by preventing hot air migrating through the walls and being wasted. This will in turn prevent money spent on heating bills from being wasted and create a temperature-controlled environment.

Unilin Insulated Plasterboard

The insulation layer is a rigid polyisocyanurate (PIR) core with strong Kraft paper facings bonded to each side, available in a variety of thicknesses to best suit your project requirements. The insulation will slow down the rate at which hot and cold air travels through the board.

The plasterboard is a 12.5mm tapered edge standard drywall board made up of a high-grade aerated gypsum core bonded within superior kraft paper linings. This serves as the interior wall and gives a level surface ready for skimming and plastering, the tapered edge will help to achieve a flawless finish.

The premium quality kraft facings on each side of the board has an incorporated vapour control layer (VCL). The integral vapour control layer will help to reduce the risk of condensation occurring and moisture passing through the boards.

The Benefits of Unilin XT/TL Insulated Plasterboards

  • Multi-purpose Board: can be applied to walls and partition walls within both new builds and refurbished residential and commercial buildings
  • Thermal Comfort: Reduces heat levels transmitting between walls from external and internal factors
  • Energy Efficiency: The combination of insulation and drywall will help to maintain a consistent indoor temperature, reducing costs from heating and cooling
  • Quicker Install: The combination of products simplifies the installation process in comparison to installing two separate layers, reducing labour and turnaround times
  • 2-in-1: Insulation and drylining available in one solid application
  • Aesthetical Finish: The surface of the plasterboards is ready for direct decoration whether that be paint, wallpaper, or other finishing products
  • Vapour Barrier: This board provides an effective vapour control layer that is integrated into board, providing further protection against condensation, moisture, and damp

Unilin boards are 2400mm x 1200mm and are available in thicknesses between 37.5mm and 72.5mm with a coverage of 2.88m2 per board. Unilin XT/TL Insulated Plasterboards have a thermal conductivity of just 0.022W/mK.
Unilin insulated plasterboards are stable and rot proof. They provide no food value to vermin. The boards are designed to last for the entire lifespan of the building, depending on the quality of installation. The boards should be kept clear of all liquids and chemicals.

Application Types

The Thin-R Unilin tapered edge thermal liners are made for the application of internal walls and sloped roofs. The Unilin insulated plasterboards are suitable for dot and dab applications on solid walls, mechanical fixings to timber battens or studs, and mechanical fixings to steel framing systems. These versatile applications are due to their kraft paper facings. The boards can be used in addition to other insulation materials.
Unilin Xtratherm insulated plasterboards are a great product for loft or attic conversions when creating a room-in-the-roof. The insulated plasterboard can be combined with insulation boards or rolls, this combination of products can be applied directly to rafters within the roof and walls to insulate the space while creating a finished interior surface.

Unilin insulated plasterboard products need to be stored above ground on a flat surface. The boards should be protected from the elements and extreme temperatures. It is advised the boards are stored under cover. When cutting the Xtratherm Unilin insulated plasterboards, be sure to measure the boards to size beforehand and cut using a sharp knife or fine-toothed saw. If you are using Unilin to renovate an existing property, a building professional should be consulted to ensure that the property does not require any construction work or treatments prior to the insulation. Applying Unilin insulated plasterboard to damaged walls could affect the quality of the boards and worsen the existing damage.

FAQs

Can Unilin Insulated Plasterboard be applied to existing walls?

Yes, insulated plasterboards can be applied directly to existing walls using the dot and dab method providing the boards have a high-quality paper backing and not a composite foil lining. Adhesive and composite foil sometimes causes problems when it comes to bonding as the board may slide from the bonding compound.

Can Unilin Insulated Plasterboards be used for soundproofing?

No, Unilin insulated plasterboards cannot be used for soundproofing purposes. Although the board may have soundproofing benefits and reduce noise, particularly when using a thicker board, to significantly reduce noise levels you would need to consider a specialised soundproofing solution such as acoustic plasterboard or insulation.

Can I Use Unilin XT/TL Insulated Plasterboards instead of Celotex PL4000 Insulated Plasterboard?

Unilin insulated plasterboards are a great alternative to Celotex insulated plasterboards. Both insulation boards have a polyisocyanurate (PIR) core with a thermal conductivity of 0.022W/mK bonded to a 12.5mm tapered edge plasterboard with high quality paper-facings on each side. In conclusion the Unilin Insulated Plasterboard sand Celotex Insulated Plasterboard are a like-for-like product.

Can damp get though Unilin insulated plasterboard?

Damp can travel through an insulated plasterboard if the Vapour Control Layer (VCL) has been damaged or is not continuous, this will cause gaps in which damp can get through. This can worsen in areas where there is lack of ventilation which can cause significant. This can be prevented by applying foil tape to the board joints to strengthen the VCL, avoid damage to the boards, and be sure to provide adequate ventilate and air exchange.
