Planning roof insulation with rigid PIR boards

The key decision when insulating a roof with PIR boards is choosing the whole layer build-up, not just the insulation thickness. Before buying, check that the substrate is dry and loadbearing and whether the existing layers need replacing. Also settle how you will detail the junctions at the eaves, wall plate and openings, as these determine airtightness. A board with a thin aluminium facing remains an insulation material, not a roof sandwich panel. Without a detailing plan, even low lambda will not guarantee the expected performance.

How to insulate a wall internally at the boundary and not lose too much space?

When a wall stands at the plot boundary, adding a layer on the outside may be difficult. Internal insulation then requires a good balance of space and moisture. The full thickness of the build-up must be calculated, not just the core of the board. Particular attention is needed at windows, cross walls and the junction with the ceiling and floor. Check the actual course of the boundary and the situation of the building. Do not assume that the existing façade can be thickened at will. Formal requirements and the feasibility of external works are determined separately. The conditions of a specific property may affect the available solutions.

Where do sandwich panels and PIR insulation fit into modern construction?

An insulated panel can close a wall or roof while reducing heat loss. A separate PIR board is used to insulate a building element that has its own structure and covering. These materials make construction easier, but they are not interchangeable. The choice is determined by the building's function, the support layout, moisture and fire requirements. The greatest benefit comes from selecting the whole solution before ordering materials. An insulated panel has two metal facings bonded to an insulating core. The components work together when carrying loads. As a result, the finished panel can form the envelope of a hall, workshop or warehouse. It still requires designed supports, however. The term self-supporting does not mean it will replace columns, purlins and the entire building structure.
