A lot of heat energy is required to change the temperature of high density materials like precast concrete and this is why concrete has high thermal mass.
Thermal mass concrete walls.
We manufacture and distribute a full line of concrete insulation systems for use in plant precast site cast tilt up and cast in place projects.
Thermal mass walls come in two forms.
This is typically achieved through its ability to absorb unwanted heat during the day and then release it at night with the help of ventilation from cool night air.
A wall material with high thermal mass can moderate daily temperature variations.
Concrete slab floors should be 100 200mm thick for the best performance while thermal mass walls should be 100 150mm thick.
Introduce thermal mass within lightweight structures by using isolated masonry walls water filled containers phase change materials pcms or lightweight steel framed concrete floors.
With over 35 years of experience we are the undisputed leader in concrete sandwich wall technology and can help you create building envelopes that maximize energy efficiency durability and performance.
Precast panels are manufactured at a plant and delivered to the job site.
Very thick thermal mass walls and floors may take too long to heat while those that are too thin won t store enough heat.
Nudura walls have a high storage capacity with low thermal conductivity providing the most useful level of thermal mass.
Internal or enclosed water features such as pools can also provide thermal mass but require good ventilation and must be capable of being isolated as.
The monolithic concrete is layered between two continuous layers of 67mm thick eps foam which isolates the concrete and significantly reduces the flow of heat through the wall.
With integral insulation some of the thermal mass masonry is directly in contact with the indoor air which provides excellent thermal mass benefits while allowing exposed masonry on both the exterior and interior.
Thermal mass for limiting summertime overheating.
It is therefore most commonly associated with solid concrete floor slabs in naturally ventilated or low energy mechanically ventilated buildings where the concrete soffit is left exposed to the occupied space.
Wooden walls by comparison are much easier to heat with their lower thermal mass.
The exact amount should be calculated as part of the design process.
Multi wythe cavity walls contain insulation between two wythes of masonry.
