Topargex® is recommended for:
Single-family, multi-family and commercial housing
Public buildings: schools, hospitals, …
Offices and industrial buildings
Anywhere where a comfortable living space needs to be created
Topargex® has been developed in cooperation with several European laboratories, universities and leading producers of industrial construction materials. The patented production process of these building elements through high-tech installations guarantees a high stableness, stability and pressure resistance.
Thanks to the intrinsic features of the Argex granules (40% air enclosed in baked and expanded clay) integrated in the concrete skeleton, many experts consider Topargex blocks the ultimate combination of often conflicting features like bearing power, isolation, warmth and acoustic comfort. The big amount of air is striking for a building element that comes across as heavy but is surprisingly light, a feature not to be underestimated, since lightness gives way for a speedy processing and guarantees cheaper logistical expenses.
K value of 0.54 W/m²K with “only” 3 cm of insulation (λ = 0.04) for 14 cm thick Topargex blocks, heat loss through the joints λ = 0.35 W/mK
reaction of the wall to temperature fluctuations, “how comfortable the wall feels to touch”; the heat capacity of Topargex blocks is twice that of cellular concrete blocks
There is no difference between a concrete wall and a Topargex wall, in spite of the fact that the latter’s density is just half. This is due to the microporous cellular structure of the expanded clay pellets.
E.g. 14 cm thick block (4/1.2) > 47 dB attenuation
Topargex walls have excellent sound absorption characteristics. NRC value = 0.50 – even with two paint layers.
Topargex blocks provide excellent results in relation to fire-resistance.
Some examples: Solid 14 cm Argex blocks: Rf = 3 hours, 19 cm = 6 hours
Topargex blocks have enough compression strength to be used for the construction of buildings of up to three stories.
As this is a cement-bonded product, radiators, cabinets etc. can be fixed to the wall without special plugs, and stay there for a lifetime. Other (baked) bricks are performing much worse in this regard.
Because of the rough surface, there is no need for any extra binder coating (as there is with bricks/hollow blocks). This reduces the cost of rendering and ensures cleaner/straighter plastering.
Topargex blocks are easy to handle, bond easily with the mortar and can even be glued in place. Because of their low weight and large size (on average 35% greater surface area than a hollow block) a bricklayer can get much more work done in the same time.
