100mm Unilin Thin-R XT/CW Partial Fill Cavity Wall Insulation (T&G) is typically used in external walls of buildings with cavity wall construction.
PIR Insulation
The polyisocyanurate (PIR) Insulation board is one of the most used material in construction that is primarily used for pitched roofs, walls, and floors for domestic and industrial projects. Providing the most desirable brands such as Ectotherm, Recticel and Kingspan PIR insulation with various thicknesses from 20mm to 150mm with an excellent thermal conductivity of 0.22 k/mK throughout all thicknesses and superb compressive strength.
PIR foam is made through a chemical reaction that results in a closed-cell structure that traps gas. Because this gas transfers less heat than still air, it is one of the most energy-efficient insulating materials on the market.
The material’s low thermal conductivity, combined with its ease of handling and versatility in a variety of applications, has made it increasingly popular among architects and contractors.
Types of PIR Insulation Panels
- Foil faced PIR Boards (Ecotherm Eco-versal, Recticel Eurothane GP, Kingspan Thermapitch TP10, Thermawall TW55, Thermafloor TF70)
- Cavity PIR Boards (Kingspan TW50)
- Mineral coated glass faced or bonded to plywood PIR boards (flat roofs Kingspan Thermaroof TR24, TR26 and TR27)
Advantages of PIR Board Insulation
- PIR is light comparing to mineral wool insulation.
- Easy to install – – simple handling, straightforward application.
- Reduces Heat Loss
- PIR insulation is thin which means less material results in lighter structures and saves on building materials.
- The foil facings have a high-water vapour resistance and will, therefore, provide a significant resistance to water vapour transmission.
- Resistant to the damage caused by water vapour and mould
- Excellent coverage – provides coverage area of 2.88m2
- Manufactured with a blowing agent that has zero ODP and low GWP Insulation.
