Photographs illustrate material types, not stock availability. The λ values are manufacturer examples, not design inputs for your building.
Boards and rolls for walls, roofs and floors. Loaded areas and facade systems require purpose-rated products; density alone does not establish strength.
Example: ISOVER Profi — λ 0.037 W/(m·K). Confirm the design value separately.

Flexible framing batts and rigid boards for approved systems. Thermal storage can moderate temperature changes; moisture protection is still essential.
Example: STEICO flex 038 — λD 0.038 W/(m·K), not a value for all wood-fibre boards.

Plant-fibre insulation for suitable framing systems. Composition, additives and fire performance depend on the product; fibre type alone does not guarantee resistance to mould or pests.
Example: THERMO HEMP Combi Jute — λD 0.043 W/(m·K).

For walls, floors and roofs within the product’s approved applications. Check binder, additives, density, fire documentation and protection from water.
Thermal conductivity and permitted moisture conditions: selected product data sheet.
Blown material for cavities and floors. Equipment, installation density and enclosure preparation determine performance. Framing and fixing thermal bridges still require assessment.
Example: ISOCELL — 0.038–0.039 W/(m·K), depending on the rating method.

Rigid insulation with low conductivity. Facing and application follow the data sheet. Fire class and suitability beneath render cannot be generalized across all PIR boards.
Example: LOGICPIR — λ 0.022 W/(m·K); confirm the design value and facing for the grade.

Different material families. XPS is often considered for plinths, floors and inverted roofs; EPS for systems designed to use it. Check water absorption, strength and fire restrictions.

Design follows applicable thermal-protection requirements, including Russian SP 50.13330.2024 where relevant. Climate, building use, layers, moisture conditions and thermal bridges matter. A fixed 50 or 100 mm is not a universal solution. СП 50.13330.2024 ↗
For a hypothetical uniform section requiring R = 3.2, with existing layers and surface resistances providing R = 1.7 m²·K/W, the deficit is 1.5. At a hypothetical design λ = 0.040 W/(m·K), δ = 0.060 m, or 60 mm. This explains the arithmetic only; thermal bridges, moisture and junctions must still be assessed.
Internal lining, designed vapour-control layer, insulated frame, system-specific outer protection, ventilation cavity and cladding. Cavity size and membrane use follow the system design.
Use a documented compatible system of insulation, adhesive, fixings, reinforcement and finish. Foil-faced PIR is not automatically suitable for render; XPS also requires an approved application.
Increasing outward vapour permeability can guide design but does not prove a wall safe. Not every masonry wall needs an added vapour barrier; position, properties and drying capacity require assessment.
