Recticel EuroWall board, 50 mm thick with aluminium-laminated facing

A warm loft bedroom, a comfortable terrace threshold and adequate ceiling height all depend on using the available space well. PIR insulation boards help limit heat loss in a relatively thin layer. Where every centimetre counts, this can preserve usable room dimensions and everyday comfort.

Rigid PIR foam has low thermal conductivity. For the same thermal resistance it can be thinner than a material with a higher lambda value. That is useful when windows, thresholds and headroom below a roof already set the dimensions. Match the board to the available depth and required performance. The same approach can help when planning details for a new building.

Rigid boards come with different facings for use in roofs, floors and walls. Check the facing and declared properties against the layer in which the board will sit. Insulation slows heat transfer and can help reduce summer heat gain through the building fabric. Ventilation and the rest of the building also affect indoor temperatures. In a small loft bedroom, preserving space beside a slope can leave room for a bed or wardrobe. In a living area, it can help retain the planned ceiling height.

Light boards are easier to carry into parts of the building under renovation.

Regular sizes simplify layout planning on large, flat areas.

Profiled edges help maintain the insulation layer at board joints.

A choice of facings lets you match the board surface to the assembly.

Consider PIR when converting a loft, insulating a floor above a cold room or upgrading a roof. Under a floor, check the board’s strength against the expected loads. On terraces and flat roofs, thin insulation can help match adjoining heights. The result can be more usable space beneath a slope, easier access at a threshold or more freedom to arrange the room. Choose the board grade for its location.

SteelProfil offers first- and second-grade PIR boards, including stock for immediate supply. We help compare current prices, thicknesses, facings and formats against the space and intended use in your home or commercial building.
