Utherm Floor LE in service rooms: specifying the floor beneath equipment

Show the substrate levels on both sides of the doorway and the required finished level. Work down from that level using the actual floor coverings and their bedding. If the plant room tiles are thicker than the office covering, there is correspondingly less depth for screed and insulation.

Utherm Floor LE has a PIR core with grid-printed laminate facings on both sides. Unilin declares a thermal conductivity of 0.022 W/(m·K) and a resistance of 2.70 m²K/W for a 60 mm board. Enter the full board designation and the specified thickness for each room in the schedule.

For a ground floor, the designer also needs the plan geometry and perimeter conditions. For an intermediate floor, the temperatures in the rooms above and below matter. Indicate which condition applies to the office and which to the plant room.

Check where service runs converge near the cabinet. Place a trial board on the prepared base and see whether it bears on a projecting conduit. A board that rocks under light pressure identifies an area to inspect again before continuing.

Lay out perimeter cuts for the board size ordered. A 1,200 × 600 mm board has a nominal area of 0.72 m². Keep the cut edges continuously supported around the cabinet recess. Agree how service channels are to be levelled before covering them.

If underfloor heating is specified, show circuits, screed bays and future fixing points on one drawing. The grid on the facing helps with measurements. Take pipe spacing and details for crossing movement joints from the coordinated heating and floor design.

Before screeding, check how the movement joint will pass through the doorway between the office and plant room. Its position in the finish should match the specified detail. Record its width and alignment for the tiling crew.

For a cabinet with four feet, the supplier may give different reactions at each support. Send these figures and the contact area of each foot to the designer. Uneven distribution of equipment inside the cabinet can increase the load on one side.

Where there is an occupied room below, check the acoustic requirement for the floor and supporting slab together. Inspect the screed isolation at walls and service penetrations. Rigid contact at these junctions can transmit vibration even where a resilient layer is provided across the floor.

Compare quotations on the same scope. List the area needing levelling, insulation quantity, screed type, finish and doorway details. Price any specified reinforcement or bases for heavy equipment separately.

At handover, record the room number, installed board thickness and finished floor level. Include a photograph of the pipe routes and offsets from fixed walls to pipe centrelines. These records help locate services before new equipment is fixed down.

Suppose a replacement cabinet rests on two runners in place of four feet. Even if it fits the same recess, the location and shape of its contact areas change. Before replacement, compare the support diagram with the as-built drawing and check the delivery route through the adjoining office.
