Recticel Eurofloor beneath a staff-area floor. Insulation and imposed loads

Start with a plan showing the fittings expected in service. For a filing cabinet, record its loaded weight, number of supports and foot dimensions. For a delivery trolley, identify its route and maximum wheel load. These figures distinguish concentrated loads from loads spread over a larger area.

Where the staff area adjoins a store, mark the line at which the floor specification changes. Racking or machinery on the other side may need a separately designed base. A detail reference helps installers locate the boundary before the partitions go up.

Eurofloor carries the designation CS(10/Y)120. The 120 kPa level relates to a short-term compression test at 10% deformation or at compressive strength if reached earlier. In a finished floor, much smaller settlement may affect tiles, joints or door clearance.

Give the designer the support details together with the screed type and thickness. The position of a support relative to a movement joint or panel edge can affect load distribution. Long-term assessment requires material data appropriate to the loading period and allowable deformation.

Recticel’s Polish data sheet of February 2026 gives a declared conductivity of 0.022 W/(m·K) for Eurofloor. Declared resistance is 3.60 m²·K/W at 80 mm and 4.50 m²·K/W at 100 mm. The extra 20 mm increases the resistance of the insulation layer by 0.90 m²·K/W.

Measure the difference in substrate levels at the office-to-hall doorway. Work down from the finished floor level, allowing for the floor finish, heated screed and other layers. The remaining depth is available for insulation. A ground-floor U-value calculation also takes account of building geometry and ground conditions.

A 1200 × 1200 mm board covers a nominal 1.44 m². Mark columns, wall offsets and door recesses on the take-off drawing. Dividing the area by 1.44 gives a theoretical quantity. A cutting layout shows whether an offcut from one bay will fit the next.

Eurofloor has square edges and foil facings on both sides. The printed grid helps installers measure distances. Take pipe spacing, movement-joint crossings and circuit boundaries from the heating layout for the particular room.

At the wall junction, show how the floor damp-proof layer terminates and connects to the wall damp-proof course. The factory foil covers the board face. Continuity of protection across the floor also depends on joints, corners and service penetrations.

At the threshold, coordinate the screed edge, perimeter strip and any pipe crossing with the heating and flooring trades. Include the building’s fire requirements. Reaction-to-fire class F applies to the Eurofloor product. The completed build-up has to be assessed with its other layers.

Before the heating installers start, check for boards rocking on uneven areas of the substrate. Inspect joints at columns and row ends. At handover, record board thickness and any repaired locations, and identify photographs by room number.

Immediately before screeding, compare the surface condition with the handover record. Document pipe routes and joints that will be concealed. In the estimate, separate supply and cutting of insulation from protective layers, heating installation and screeding.
