ISOMUR ® Thermal insulation and moisture proofing Energy saving – a health risk? The better the thermal insulation of the building shell is, the more delicate the thermal bridges. Present day thermal insulation regulations such as the Energy Saving Ordinance (EnEV) in the case of new buildings with thermal insulation composite systems or double-leaf masonry result in insulation thicknesses of 120 mm or more. External wall and roof constructions are easily adapted. However, thermal bridges are always more problematic due to the ever-improving insulation of the building shell. This circumstance...

Thermal insulation and moisture proofing Efficient insulation of the building foundation The Isomur plus element is conceived for application in all residential building masonry work and complies with masonry strength class 20. The use of Isomur plus mitigates the risk of moisture damage internally in the form of discolouration and fungal formations. The requirements on load-bearing capacity and serviceability are entirely fulfilled under practical conditions. Isomur plus solves the problem of thermal bridges on wall bases: The element is non-absorptive and therefore the thermal insulation is...

ISOMUR ® Thermal insulation and moisture proofing Comparison of insulation measures Building foundation with no special measures For building foundations with no special measures the rising masonry work interrupts the thermal insulation shell of the building between the exterior wall insulation and the insulation over the basement floor. Thus in connection with the high thermal conductivity of the building bricks in the vertical direction (λ ≈ 1.0 W/mK) a massive thermal bridge forms on the building foundation. This means: Decline in the internal surface temperature with the resulting risk of...

ISOMUR ® Fire protection and sound insulation Fire protection Fire protection requirements The fire protection requirements relating to building walls are determined by the respective Federal State Building Regulations.The fire protection requirements relating to supporting walls of non-detached, residential, low-height buildings (i.e. the highest floor level is nowhere more than 7 m above ground level) are at least F30-B according to Model Building Code. In a specific case the provisions in the applicable Federal State Building Regulations must be observed. Fire-resistance ratings F30 and F90...

Energy Saving Ordinance (EnEV) The designer is offered three possibilities for quantitative determination of the effect of thermal bridges: 1. No proof of thermal bridges The heat transfer coefficient is increased by ∆UWB = 0.10W/(m2K) for the total thermally-conductive surface area. 2. Thermal bridge proof in accordance with DIN 4108, Supplementary Sheet 2 For construction details corresponding to the design examples in accordance with DIN 4108, Supplementary Sheet 2, an increase in the heat transfer coefficient for the total thermally-conductive surface area by ∆UWB = 0.05W/(m2K) can be expected....

Installation instructions Installation above the basement floor Lay the Isomur plus full-surface as the first row of bricks in the layer of mortar with no butt joint mortar mix. The element position is shown by the labelling. The elements must be carefully aligned, in particular with regard to a level and horizontal bearing surface for concrete precision block masonry. The Isomur plus elements should be bricked over as soon as stability is guaranteed by the hardened mortar. When thin-bed mortar is used for the concrete precision block masonry it must be spread such that a joint thickness of at...
