MHM - Solid timber constructions

NATURAL LIVING – WITHOUT GLUE AND CHEMICALS

Massiv-Holz-Mauer®: Solid – like stone, but dry, warm and healthy!

 

Ecological construction and healthy living with MHM wall

Why you should live and work more healthily with the solid timber wall?

The MHM® wall consists of untreated wood through and through. Due to the fact that no glue, plastic film or other chemicals are used at all, no foreign matter or solvents which could be hazardous to human health are released.

Glue and plastic film are never really permeable, the natural route of moisture in wood is disturbed which means that the indoor climate is affected in a negative way. This can be avoided by MHM® wall‘s completely open design.

People with allergies will particularly feel the difference and all other residents will also notice the healthy indoor climate of solid wooden walls.

The danger of mould growth and the consequent hazard to the health of inhabitants is avoided as early as in the shell construction stage by the permeable design and by using wood which is a dry building material.

A further plus point is the self-regulating indoor climate of solid wooden houses. The walls and ceilings “breathe” with the MHM® wall because they are constructed in a permeable way and can therefore absorb vaporous humidity, store it and release it again. This characteristic has a positive effect on the inside air humidity and balances out fluctuations, so there is relatively uniform humidity depending on the season.

Wood’s natural inertia and its large mass shield off high-frequency waves effectively. The house therefore constitutes a natural protection zone, for example from mobile phone signals.

Characteristics of the MHM construction material

 

Solid, pure wood – that is our secret

 

Untreated wood without any chemicals

MHM® walls consist of untreated wood. The boards are joined together by aluminium groove pins, the resilience of which ensures extremely stable and strong wall elements. Thus, the MHM® doe not require any glue as an adhesive agent. Due to this permeable construction method and the intrinsic properties of wood, absolutely no vapour
brakes are required for MHM walls.

On the interior, no chemical wood protectors are generally required in timber constructionbecause the drying process makes the wood dimensionally stable and resistant to parasites. On the exterior, constructive wood protective measures reduce the use of wood protection agents to a minimum. Once fitted with insulating elements, the façade of MHM houses can simply be plastered.

High degree of fire retardancy

While construction materials such as brick, steel and concrete are mostly fire retardancy class F30, official measurements confirm that MSM® are actually classed as F90 B.  Wood has a further advantage: Due to the material’s low thermal conductivity, heat does not reach neighbouring rooms so quickly. Fires can only spread slowly whilst remaining controllable.

Remarkable heat storage, low thermal conductivity

The solid construction of MHM® walls and the consequent mass forms a much larger heat store than in other construction systems. The thermal conductivity of wood is so low that the surface warms up quickly.

When the indoor temperature drops, e.g. during the night, the high retention capacity means that only the indoor air and not the walls needs to be heated the following day. The so-called “phase shift”, this means the time in which a square metre of wall cools down by 1°K, is up to four times as long as with a brick.

Insulation value

The MHM wall stands out on account of its remarkable insulation value. This is caused by MHM’s unique construction method: The boards are given rabbet joints and are profiled with many small grooves which form an air cushion. These standing layers of air give the MHM wall elements insulation values which are roughly 30% better than with pure solid wood.

Timber frame houses

 

Prefabricated element houses are produced of timber frames according to client’s design. The elements itself are produced in the factory, where the indoor conditions guarantee the correct and high quality of the constructions. The prefabricated timber frame elements may include, if needed, windows (with accessories), insulation and inner and outer finishing.

We are capable to produce element houses with timber frames for different styles and purposes:

  • Single family houses
  • Detached houses
  • Terraced houses
  • Apartment buildings
  • Summer houses and cottages
  • Public buildings

Watch from the video how prefab timber frame elements are made.

 


Prefab timber elements

EstHus produces different prefab timber elements. The elements (walls, floors/ceilings and roofs) are produced and built efficiently with all services, trades and materials project managed and supervised in our factories.

 

We produce:

  • Facade elements
  • Internal wall elements
  • Ceiling/Floof elements
  • Roof Elements
  • Terrace and Balcony elements

Below are different construction layers of some example elements:

Our aim is to meet all expectations and to be reliable long-term partner for our clients.


Engineering

EstHus design team is making your dreams and wishes come true. Each prefab house begins with concept design, during which floor plans and 3D computer modelling are created. The project contain´s drawings of all key construction details of the timber frame house with detailed descriptions.

3D engineering (with Autocad and Dietrich) provides an advantage to the accuracy of timber frame house construction. In addition to house project we provide also calculations on the strength of the structure and the energy efficiency report of our timber frame houses.

In years we have gained a lot of experience at designing houses in various European countries. According to destination of house we are following local traditions and regulations and also 5th Euro Code.

 

 

We will help you to realize your dream!

 


Installation

We provide installations service of our prefabricated timber frame elements and MHMMassiv-Holz-Mauer® houses. According to installation drawings and manuals our professional mounting teams assemble building elements and modules to complete houses and give them a finishing touch.

The building process of an element and MHMMassiv-Holz-Mauer® house is really fast – the house is weatherproof within a few days. Factory production allows to reduce “the climate factor” to minimum, so it is possible to build the house in any season. Modern technologies and materials allows to build resistant, safe and durable timber frame houses that can serve up to 100 years.
