Cold Room Panel Floor Design, Load Bearing & Moisture Barrier for Forklift Operation
Cold room floor panel bears pallet, forklift and stacking cargo load; floor structure is the most easily neglected part of cold room insulation design. Light pedestrian cold room: standard PU floor panel with reinforced surface; forklift working cold room needs concrete load layer above insulation. Typical floor structure from bottom up: compacted ground → PE moisture barrier film → PU insulation panel → steel mesh reinforced concrete layer. Moisture barrier film (0.2mm PE) must be fully overlapped and sealed; underground water vapor rising penetrates foam and makes insulation fail. Xiteliduo cold room PU floor panel HS 940600 adopts high density PU core, special wear-resistant surface for light load cold room. Low temperature cold room floor needs anti-heave design; soil water freezing under floor will expand and push floor upward, crack concrete and panel. Heating wire under floor insulation is the mainstream anti-freeze heave solution for -18℃ and below cold storage, keep subsoil temperature above 0℃. Floor drainage trench inside cold room must be heat isolated; trench without insulation forms heat bridge and frost block frequently. Floor expansion joint is reserved for concrete layer; temperature shrink and expansion will crack floor slab without reserved joint. Refrigeration maintenance & repair company checks floor surface crack and local bulge; bulge is typical signal of subsoil frost heave.
FAQ
- What is the function of PE moisture barrier film under floor panel? Block underground water vapor from entering PU foam.
- What structure is needed for forklift cold room floor? Insulation panel plus reinforced concrete load layer.
- What risk for low temperature cold room without floor anti-heave measure? Underground water freezes, volume expands and floor bulges/cracks.
- What is the common anti-frost heave method for frozen cold room floor? Lay heating cable under insulation to keep soil above zero.
- What is the standard thickness of moisture barrier PE film? 0.2mm, overlap and seal all joints.
- Can ordinary wall PU panel be used directly as forklift floor? No, insufficient compression resistance and wear resistance.
- What special design for cold room internal drainage trench? Independent thermal isolation to avoid heat bridge.
- What symptom indicates subsoil frost heave? Local floor bulging and concrete crack.
