THERMAL INSULATING LIGHTWEIGHT CONCRETE WITH PORAVER®
APPLICATION
INSULATION OFFLAT ROOFS &
CEILINGS
In modern residential buildings with a fl at roof, bound Poraver® can be installed as a load-bearing roof insulation. For suspended ceilings, bound Poraver® serves as a levelling layer to cover pipelines and as an insulating base layer for underfl oor heating systems. The use of Poraver® contributes to meet the requirements of modern passive houses and ecological standards in construction.
Compared to other lightweight aggregates, Poraver® expanded glass has a very positive ratio of compressive strength to bulk density. This enables single- and multi-layer structures with very good thermal insulation properties and at the same time good compressive strength. The production of load-bearing and insulating roller shutter boxes is feasible due to the excellent properties of Poraver® lightweight concrete, as well as the thermal separation of windows, door frames and other components.
WALLS & THERMAL SEPARATIONS
Poraver® expanded glass is a lightweight aggregate according to DIN EN 13055-1 and ideal for the production of lightweight concrete. The structural and thermal insulation properties of Poraver® enable a wide range of concretes for different applications.
With Poraver® you can produce purely mineral construction materials that meet all require-ments to building physics and building biology with excellent values. Especially thermal insulation is very important. By adding Poraver®, a suitable monolithic building material can be produced depending on the application. Time-consuming and costly external thermal insulation composite systems can become superfl uous. There are many areas of application for thermal insulating lightweight concretes with Poraver®:
PRODUCTION By using different Poraver® grain sizes, thermal insulation concretes with densities from 270 kg/m3 to 800 kg/m3 can be produced. Based on the available grain fractions, an optimized grading curve can be created. Depending on the requirements, thermal conductivities of ≥ 0.07 W/(m∙K) or 28d compressive strengths of up to 13 N/mm2 can be achieved for thermal insulating lightweight concretes. In general, Poraver® can be used to produce porous and dense lightweight concretes of all density classes.
