Boss Reusable Insulated Curing Blanket 4x4m – 6mm

Boss green curing blankets insulate freshly poured concrete to ensure optimal results in cold and hot weather. By insulating the concrete from extreme temperatures, we can prevent cracking and unevenness, resulting in a better-finished product. This insulation protects against heat loss or gains.

The thermal insulation protects against heat loss on the surface, whilst the polyethylene cover protects against heat from direct sunlight. This will also help protect the concrete from natural elements such as wind and rain.

DID YOU KNOW – At 4°C, the chemical reactions that cure concrete essentially stops, and if the mercury dips below 0°C, the water in the concrete freezes which leads to pressure buildup, scaling and potentially compromises the structure. So, the greater the concrete mass, the greater the risk of thermal cracking. As concrete hydrates and cures, it generates heat and expands. Thermal cracking occurs when the warmer concrete core expands whilst the cooling outer layer contracts. The greater the temperature differential, the greater the stresses and potential for cracking.
