Insulation Technology

Most old houses are insufficiently insulated, or not at all, against heat loss.

With the help of the retrospective process of cavity wall insulation, it is possible to increase the heat insulation of walls, roofs and ceilings.
Retrospective cavity wall insulation is a technology by which insulation material, mostly cellulose flakes are blasted under pressure into cavities.
That is possible with external walls of double thickness, extended roof lofts, flat roofs and the ceilings of storeys.

In contrast to external or internal insulation, the insulation of the core is a great deal easier to implement in the construction of a wall with multiple thicknesses and achieves optimal, highly energy efficient results with relatively smaller wall thicknesses in timber frame constructions and modernisations.
Essential investments are repaid after a short time.

We use, as a rule cellulose insulation materials, beads from the firm Dammstatt W.E.R.F. Gmbh for all insulation areas in a house.

Cellulose Insulation Material

The pleasant living atmosphere of timber houses is based, amongst other things, on their heat storage capacity and their capability to absorb and release room humidity. The cellulose insulating materials also have these qualities which are decisive for the quality of the air in the room. Since the construction is done to allow humidity to escape, there is no excess humidity, since the damp air inside is defused through the roof and the walls. This guarantees the best living atmosphere and avoids the formation of mould.

Cellulose is alsoable to diffuse and breathe.

Composition:

Cellulose insulation consists of shredded waste paper that is protected against mould and pest infestation. The original material is wood that is 2x2 which can store five times as much heat energy (C value) as other materials.
The individual fibers interlock during the processing and demonstrate a high degree of density. 
The blasting into the cavity guarantees an insulation that is secure against settlement, wind and gaps.
The cellulose fiber insulation system has proved itself over more than 70 years in North America and also for over 40 years in Europe.

Further Advantages of Cellulose Insulation:

- No cutting problems in narrow places or intersections
- Saves valuable heating energy
- Saves cooling energy Very well suited to houses with air conditioning
- Excellent sound insulation
- High resistance to fire, cellulose does not burn and does not melt (even at 1200oC the material only chars slowly and goes out immediately the flame is removed)
- Renewable raw material, naturally ecological
- Low consumption of primary energy (energy for production)
- Price advantage over most other products

Ecological Sheets of Insulating Material; a mixture of wood and clay:

On request and according to your budget we will also use ecological sheets of insulating material for the roof, walls, floors and ceilings of storeys.

These sheets for example Steico Therm are made of wood fibers, a minimum 75% of which come from sustainable timber industry. This material is known for its extraordinary heat efficiency in direct insolation.

It is available in all thicknesses and two different compositions:

Insulating wedges – less pliable and therefore more pressure resistant (for example for floors etc)

Insulating mats – softer and can be used to fill and insulate an existing ceiling because of the various different distances between the beams.

Clay , Stones and Plaster

A further possibility to insulate your house ecologically is with clay, stone and plaster Clay and wood are “like brother and sister”.

They guarantee an optimal regulation of humidity and heat, they store the heat in winter and provide for a cool room climate in summer. In addition they offer good sound proofing.
