PIR boards for external wall insulation systems (ETICS)
Insulating external walls changes the proportions of a house. Deeper window reveals, the eaves junction and the width of a path alongside the wall can affect both appearance and everyday use. PIR boards designed for external thermal insulation composite systems (ETICS) can provide the required thermal resistance within a limited build-up. This helps retain the details that matter in a new design or refurbishment.
Keeping the proportions of the façade
For the same thermal resistance, PIR’s low thermal conductivity allows a thinner layer than a material with a higher lambda value. This is useful on a tight site or where deeper reveals would alter the character of the windows. A thinner build-up can simplify connections to existing frames and preserve usable passage width. It gives the owner greater scope to retain the proportions intended by the original design.
ETICS requires boards with facings compatible with the layers in the specified system. Glass fleece is one example. Both the core and the facing have a role to play. Choose a board covered by the system specification so the façade is built from components intended to work together. The render provides a familiar finish, while the insulation beneath it improves comfort in rooms along the outside wall. Planning the overall depth also helps achieve balanced proportions around sills, window surrounds and the areas of wall between windows.
Rigid boards in a regular format help form an even insulation layer.
The specified facing allows the board to be matched to the façade system.
The lightweight insulation is easier to carry to upper storeys.
A choice of thicknesses helps resolve critical details and junctions between sections of the façade.
Refurbishing an existing home
Consider PIR for ETICS where the façade has little room to grow, for example alongside narrow paths, on small balconies or around elaborate window frames. On a new house, choosing the build-up early helps set the proportions of openings and corner finishes. For residents, external insulation reduces heat loss through the walls and improves indoor comfort. A compatible system can meet practical and visual requirements while preserving the intended geometry, especially where individual junctions need careful detailing.
