A house can retain the proportions of its façade after insulation without creating very deep window reveals. PIR boards designed for external thermal insulation composite systems (ETICS) provide effective insulation in a limited thickness. This is particularly useful when upgrading a building with short eaves or little space around existing details.
A rigid PIR core offers good thermal resistance at a relatively small thickness. This gives you options where the wall must stay clear of a boundary, fit under an existing canopy or accommodate narrow window reveals. It also affects how the building looks. The new insulation can avoid excessive projection, helping the windows remain in proportion with the façade divisions and the width of their surrounds.
An ETICS board has a surface intended for a particular façade system. Some PIR boards have glass fleece facings, while other systems use a composite board with an EPS layer. The appropriate surface connects the insulating core to the reinforced base coat and render. This gives the exterior a conventional rendered appearance with high-performance insulation underneath.
In a corner room or a living room against an external wall, the difference is felt in everyday comfort. Insulation on the outside reduces heat loss through the masonry and helps maintain more stable indoor conditions. It takes up no floor space inside. A façade renovation can therefore improve comfort while keeping the furniture layout, window space and room dimensions a household already likes.
Rigid boards can be fitted around reveals, along the plinth and at elements that pass through the façade. Careful detailing maintains the insulation layer at these junctions. On the main wall areas, the regular board format helps create a flat base for the subsequent coats. New render colours and textures can be chosen to suit the house, while small windows and narrow stretches of wall retain balanced proportions.
Specify a complete compatible ETICS with the correct PIR boards, mortars, fixings and finishing layers. Each component performs a defined function. When they are selected together, you can combine a slim build-up with a durable façade and an even base for the finish. This is especially valuable when an existing building has difficult junctions and the design calls for both thermal resistance and flexibility in the finished appearance.
