Sheathing boards serve as a fundamental component in the realm of construction and insulation, offering structural stability, thermal performance, and resistance to external factors. When perusing through the expansive options available on Insulation4Less, it’s crucial to understand the multifaceted applications and variations among these vital boards. Let’s delve into two notable products within this category, distinguishing their characteristics and utilizations.

PIR Sheathing Boards

Unilin Thin-R PIR 125mm x 2.4m x 1.2m

PIR (Polyisocyanurate) sheathing boards like the ones offered by Unilin are renowned for their exemplary thermal performance. Tailored to facilitate energy efficiency, these boards integrate a dense and rigid thermal insulation core, effectively reducing heat transfer through walls, floors, and roofs. With variants like the Unilin Thin-R PIR, you can expect:

  • High Thermal Efficiency: Ideal for situations demanding maximum insulation with minimal thickness.
  • Versatility: Capable of being used in an assortment of applications, including walls and roofs.
  • Durability: Resistant to moisture and capable of maintaining structural integrity over time.

 

Typically, PIR boards are chosen for their lightness, easy installation, and reliable thermal performance, making them a favourite in both residential and commercial insulation applications.

Gypsum-Based Sheathing Boards

Glasroc X Sheathing Board - 2400mm x 1200mm x 12.5mm

British Gypsum offers the Glasroc X Sheathing Board, a gypsum-based sheathing solution notable for its robustness and resistance to external elements. This type of board is often implemented due to its:

  • Weather Resistance: Engineered to endure exposure to elemental forces during construction phases.
  • Fire Resistance: Intrinsically fire-retardant, offering an additional layer of safety to structures.
  • Impact Resistance: Adept at absorbing and dissipating impacts, protecting the structural integrity of buildings.

 

Gypsum sheathing boards are indispensable in scenarios where the protective, fire-resistant and robust character is imperative, such as external walls or buildings exposed to harsh environmental conditions.

Selection Guide

Selecting between PIR and gypsum-based sheathing boards often boils down to your specific use-case scenarios and requirements. Here are a few guiding principles:

  • For Optimal Thermal Performance: PIR sheathing boards, like Unilin Thin-R, provide high thermal efficiency, ensuring the conservation of energy and maintaining interior temperature stability.
  • For External Robustness: If you seek a solution that will stand resiliently against weather, fire, and physical impacts, the gypsum-based Glasroc X Sheathing Boards should be your port of call.
