The problem this product solves

Houses today are mostly built using plastic to prevent moisture from migrating from inside the house to the wall's insulation. Since the insulation usually can not handle moisture, the house is in danger of mold growth and unhealthy indoor environment as a result. With IsoTimbers building technology it is the air ducts in the wood that insulates. In a construction of wood and air, moisture can travel from the inside to the outside, through diffusion. This allows IsoTimber to produce insulated and load-bearing walls without the unhealthy plastic sheeting, giving the owner the basis of a climate and healthy household.

How the product solves it

Insulated wallblocks are created by robots cutting out air ducts in the wood. These wallblocks are covered with plywood on the inside and outside. Competing solutions require more operations and components in the wall, including unhealthy plastic wrap. The IsoTimber production way contains environmentally friendly components, few production steps and a high degree of automation. It is therefore possible, with the right investments, to quickly increase the production volume and lower the production cost per manufactured wall.

Product features

IsoTimber wall systems are strong and insulating. The air and wood do wonders. It also gives high thermal insulation values. To get the same insulation values from solid wood, the wall thickness needs to be doubled.
  • Eliminates both drafts and cold bridges, providing cheaper heating.
  • Good soundproofing. More quiet indoors, when you build in town or along the roads. 
  • Good insulation during summer – nice and cool inside.

Product use cases

IsoTimber's product is used as a backbone to houses and garages. It is an environmentally friendly alternative to the conventional house structure.

Target Market

Currently, the main market for IsoTimber is Sweden and Norway. The demand for IsoTimber is increasing, and one of the company's long-term goals is to deliver wall systems worldwide, preferably to other construction companies.

Competitive landscape

In Sweden, there are about 100 companies in the timber industry that employ more than five employees. These companies are the main competitors. Other large and small construction companies can also be counted as competitors, or be considered as potential customers.

Largest competitors in terms of turnover are:
  • Älvsbyhus 1 000 MSEK
  • Myresjöhus 817 MSEK
  • Moelven 787 MSEK
  • Götenehus 523 MSEK

Fiskarheden is below the above-mentioned companies in terms of turnover, but in terms of their 400 delivered houses, they are above. Fiskarheden is the competitor who is closest to IsoTimber when it comes to business model.

Unique differentiator from competitors

With the technology, IsoTimber can deliver turnkey houses that are:
  • Environmentally friendly, contributing to the fight against global warming.
  • Simple to produce, build and mount.
  • Built on just wood and air; natural materials that balance moisture content and contributes to healthier indoor environments.
  • Possessing a density level that meets the requirements for low-energy and passive houses.
  • Inducing sound reduction, helping tenants avoid noise.
  • Simple to retrofit with additional detail.

Company revenue streams

IsoTimber currently makes 100% of it's revenue from selling ready-made building packages and turnkey houses.

Low production costs and fast assembly of building packages means that the final price for the customer is attractive, while it is an environmentally friendly, durable and flexible option.

Product/service distribution


Previous milestones/traction

  • Pending patent application on the technology behind IsoTimber.
  • The use of CNC machines which produce customized wall blocks. This more machine-intensive production method enables greater precision, providing higher capacity.
  • Great attention in the media – TV4 , SVT and NRK made TV spots in 2014 about IsoTimber. The most significant one was in the popular TV show "Äntligen Hemma". The broadcast was watched by 750 000 viewers and has given extremely large effects in terms of inquiries and quotations to the company.

Next key objectives

  • Streamlined production and higher margin  Increase the capacity of production, achieve higher levels of automation and thus lower production costs.
  • Reinforce the organization – To deal with the increase in demand and the planned expansion, more resources are required in finance, sales, project and production management.
  • Market Focus – Many are interested, but lead times in the industry are relatively long. It is a big decision to build a house and it takes time to get the building permit. It is therefore important to increase marketing efforts.
  • Revenue – 2016: 20 MSEK, 2023-2026: 500 MSEK

Previous Financing

Over the years, IsoTimber has been mainly financed by private capital and loans. The capital has been used for product development and company expansion. In connection with the ongoing rights issue, Almi Invest AB and Ekonord AB, which each had a convertible loan of 5 million, chose to convert their convertible bonds into shares in IsoTimber.

Use of funds

The financing capital will be used to increase production capacity to meet the increase in sales and deliveries. The building blocks need to be produced faster and at a higher level of automation. This means investment in machinery. The money will be invested in stages but IsoTimber can start the expansion plans already after the first five million. A goal that is already fulfilled.
