The Product - our flatpack housing

The Frame System 

We produce flatpack housing within a “first phase” delivery. A “first phase” delivery embrace the construction part of the house which includes:

  • Timber frame walls with triple glazed windows, external doors and balcony doors.
  • Roof trusses with roofing boards, roofing felt, battens and counter battens.

A flatpack housing within a “first phase” delivery represents about 30% of the total cost for a completed house.

The flatpack housing was originally developed in Sweden and has through the years been modified by Japanese engineers. The manufacturing process is highly automated. Today there are 37 different frames. The frames are made in the following sizes.

Heights: 2,4 metres 7,87 feet
  2,7 metres 8,86 feet
Widths: 0,3 metres 0.98 feet
  0,6 metres 1,97 feet
  1,2 metres 3,94 feet
  2,7 metres 8,86 feet (for garage door)

 

 

 

 

 

This system of construction allows you to create houses that fit every requirement.

The timber frames are made of individually selected Swedish timber with a measure of 45×145 mm (1,8 x 5,7 inches). The high-quality Lamda 33 mineral wool insulation inside the frames is 145 mm (5,71 inches). On the inside there is a 0,2 mm (0,0079 inches) thick cling film and a 9,2 mm (0,36 inches) thick board. On the outside there is a 9,5 mm (0,37 inches) thick plywood. The frames can be delivered with pre-installed vertical plastic pipes for electric cables.

Windows & Balcony doors

The windows and balcony doors are triple-glazed; each pane of glass is 4 mm (0,1575 inches) The window frames are impregnated and painted.

Trusses

The roof construction is calculated in a computerized program and are in every specified project adapted to the lokal building code and legislation in every country.

Delivery

After being produced in our factory in Sweden, the timber frames are loaded into containers and transported by train to the Gothenburg harbour for further transportation by ship. Depending on the order volume, the timber frame house can be delivered in two ways:

  1. Groups of 7 that are loaded with exact precision into one container. This is recommended way for high volume orders, with delivery to a warehouse.
  2. One complete house in one container. This is recommended way for low volume orders, with delivery to a building site.

 

Low/Zero Carbon Homes

Our approach to achieving this target is by providing the most cost and performance effective solution for each element within the building  envelope.

Walls

Our wall panels are made of from 9.5mm plywood, 145mm of insulation, 0.2mm plasticfilm and 9.3mm masonite board giving a U-value of 0.29 W/m².K. Additional insulationcan be added inside the building between the wall panel and plasterboard or woodto enhance the U-value further (2x45mm insulation results in U-value of less than W/m².K) 

Windows

Our windows are of the the highrst quality and are pre-installed in each panel in the factory making them extremely airtight. All windows are triple glazed and argon filled. All openable windows rotate 180 degrees. The windows have a U-value of 1.2 W/m².K

Ceiling, floor and roof

The floor system can be insulated on site easily but is supplied with a 0.2mm thick plastic film which in turn ties to the wall panels to form an airtight envelope. This also applies to the ceiling.

The roof is supplied with tongue-in-groove boards (sarking boards) to further enhance air tightness, structural integrity and forming an additional barrier to water.

Insulated Foundation option

Our insulated foundation system not only provides excellent U-values from 0.15 - 0.2 W/m².K but also significantly reduces the amount of ground work, earth removal and disposition. Typically a small amount of concrete is placed on top of 150mm hard core within our prefabricated EPS pieces providing a raft foundation which is extremely fast to build (3days with one stage pour concrete). Underfloor heating can also be embedded within the foundation at this stage.
