The ambient temperature and weather requirements for rock wool board construction require comprehensive consideration of temperature range, wind conditions, precipitation control, humidity balance, seasonal protection, construction time selection, and emergency measures to ensure stable material performance and reliable construction quality.
Construction temperature is a key factor affecting rock wool board performance. The base layer and construction environment must be maintained above 5°C throughout the construction process and for 24 hours after construction. Low temperatures reduce the activity of the binder in the rock wool board, affecting the bond strength with the base layer. This can also cause embrittlement and increase the risk of cracking later. If construction is carried out in winter, the base layer must be preheated in advance and frost-resistant adhesive must be used. After construction, protective measures such as covering with a thermal blanket should be taken to prevent freezing of the material due to low nighttime temperatures.
Wind conditions directly impact construction safety and material fixation effectiveness. Construction is strictly prohibited in winds of force 5 or above. Strong winds can dislodge unsecured rock wool board, posing a safety hazard. They can also accelerate moisture evaporation from the surface of the material, causing premature drying of the adhesive layer and compromising bonding quality. During construction, closely monitor weather forecasts and choose periods of low wind speed. Install windbreaks around scaffolding or work surfaces to minimize the impact of localized wind speeds on construction.
Precipitation control is crucial for ensuring construction quality. Construction should not be carried out during rainy or snowy weather. Immediate protective measures should be taken on existing areas, such as covering with plastic sheeting or tarpaulins, to prevent rainwater from eroding and potentially damaging the adhesive layer or swelling the material. If unexpected rainfall occurs during construction, work should be stopped immediately, and unhardened areas should be protected immediately. After the rain, check the moisture content of the base layer to ensure it meets construction requirements before continuing.
Humidity balance is crucial for stable material performance. The base layer should not exceed its equilibrium humidity with the surrounding environment. Excessive humidity will reduce the thermal insulation performance of the rock wool board after absorbing moisture and may also cause mold and deterioration in the adhesive layer. Before construction, the base layer should be tested for moisture content. If the moisture content exceeds the standard, it should be treated by drying or extending the drying time to ensure that the base layer is dry before installing the rock wool board.
Seasonal protection requires adjusting the construction plan based on different climatic characteristics. During high summer temperatures, construction must avoid deformation caused by direct sunlight. This can be mitigated by erecting a sunshade or adjusting work schedules (e.g., working in the morning and evening). Winter construction requires special attention to prevent frost damage. In addition to implementing insulation measures, the adhesive material should also be heated to ensure fluidity and bond strength.
The construction period should balance efficiency and quality. Early morning and evening, when temperatures are lower and humidity is higher, hinder the drying of the adhesive layer. Critical work should be avoided during these times. Midday, when temperatures are higher and winds are lower, is an ideal construction time. Construction schedules should be rationally arranged according to local climate characteristics, avoiding rainy seasons or periods of frequent extreme weather.
Emergency measures are essential for dealing with unexpected weather events. Construction sites should be equipped with emergency materials such as tarpaulins and plastic sheets, as well as monitoring equipment such as thermometers and hygrometers to monitor environmental changes in real time. In the event of sudden rain or strong winds, work must be stopped immediately, existing areas must be protected, and unused materials must be properly stored to prevent moisture and damage. After the rain, the base layer needs to be fully inspected to ensure that there is no water accumulation and no looseness before resuming construction.
