The basics of thermal insulation

Thermal insulation

energy efficient construction. It has the greatest influence on a building’s internal temperature and thus plays a major role in reducing heating costs. That’s why there are special types of insulating materials available for every application. The experts from ISOQUICK® have a complete overview and will be happy to advise you.

Regardless whether you require comprehensive insulation for low-energy, energy-plus or passive houses, it is important that the foundations, outer walls, windows and roof work together to provide an optimum building envelope, making the transition between the individual components especially important!

Sealing

Those planning an insulated foundation usually assume that the rooms above will be heated. The insulated foundation slab separates the living space from the ground below. In particular, the DIN 18 195 standard (building sealing) should be observed. The sealing concept forms part of the planning concept. Is a waterproof concrete tank or bitumen sealant recommended? Should standing water or percolating water be taken into account? Your professional partner ISOQUICK® will cover all these issues with you.

Structural loading

No component affects the stability of a house more than the foundation, making thorough planning and execution extremely important. Technical terms such as compressive stress, shear stress, compression or the modulus of subgrade reactionpop up regularly. Because this decisive component cannot be repaired later on with minimal effort, you should rely on the professional expertise provided by ISOQUICK® right from the beginning.

Concrete reinforcement

Concrete technology and reinforcement have the largest influence on structural loading, whereby practical construction considerations must always be taken into account. Slab overlap, steel fibre concrete or self-compacting concrete must be used effectively to ensure the success of the entire project.

Frost-protected footings – drainage

The prerequisite for damage-free construction is a frost-protected footing for every building. A substantial component in this regard is properly functioning drainage. Based on a ground survey, various frost-protected footings can be used. The overall concept, however, should meet the requirements for energy efficient construction.

Foundation earthing/Ring earth electrodes

How to deal with the potential equalisation is a question that is repeatedly raised.

If ground-embedded exterior walls and the foundation slab are furnished with perimeter insulation, the earthing in the floor slab will be ineffective. This makes it necessary to position a ring earth electrode beneath the perimeter insulation in the blinding layer, ideally in the damp subsoil. Corrosion-protected stainless steel (V4A, material number 1.4571) should be used.
