The healthiest,

most sustainable homes.

Welcome to Wood100®

The healthiest, most sustainable homes

We believe wood is the most natural and healthy product to build with. We also understand that construction is a major contributor to waste. We must take whole-hearted steps to conserve our planet by doing everything as sustainably as we possibly can. Our strong environmental concern for cradle to cradle building and our mission to build the healthiest homes lie behind Wood100®.

Wood100® is Mass Timber DLT

Mass timber is a transformative technology made by affixing together many pieces of wood to form larger, stronger pieces such as panels and beams. The pieces can be glued (glulam and glued CLT), nailed (nail laminated or NLT) or affixed with wooden dowels (dowel laminated or DLT). We produce and sell only DLT, the only 100% wood mass timber product.

With wood’s natural ability to mitigate and sequester carbon dioxide this green building material has been hailed as one of the best answers to greenhouse gas emissions and climate change. Wood100®DLT is the only genuinely recyclable renewable mass timber product.

Architects, engineers and builders are realising the potential of 100% wood dowel laminated timber (DLT) as a healthy, sustainable and energy efficient building product. Depending on the application the multiple layers of wood can create panels up to 360mm thick. The solid wood panels are assembled into interior walls, floors and ceilings, roof structures and exterior walls and results in a healthy, natural shell surrounding the occupants of the home.

A truly green way of building

Wood100® really is Green Building. Today everyone claims to be building green. However closer inspection reveals that many 'green buildings' are far from it: the use of plastics, glues and resins, spray-in insulation, vapour barriers and chemicals are prevalent in many buildings, even those with passive house, LEED certified and green labels.

You may have heard of CLT taking off recently as the 'new building material' in Canada? CLT stands for 'cross laminated timber' and has been used in Europe for over 30 years. Like Wood100®DLT it is a large block of wood that comes from the layering of thinner layers of wood. (up to x layers in a 30cm block). However, unlike Wood100®DLT where the layers are connected by the wooden dowels, CLT layers are usually glued together chemically. The absolute refusal by Wood100® to use glue delivers the key benefits of our products - a truly healthy sustainable home.

How is Mass Timber DLT different than other "green" building materials?

What is a Wood100® home?

Homes can be prone to noise pollution, fire, radiation pollution, earthquake, flood, mould, unhealthy air quality and inefficient insulation. Instead of pollution filled chemicals and adhesives, our houses are made as a solid wood shell. Layers of wood connected with wooden pegs are assembled into solid wood panels (DLT) designed for interior walls, floors and ceilings, roof structures and exterior walls.

Quite simply, it's the healthiest home in the world.

It's called Wood100® because the shell of the home is made of 100% wood. The wood is grown in sustainably managed forests and harvested according to ancient traditions. Wood100® is a 100% solid wood, no glue, no chemical shell, making it a truly sustainable way to build a healthy home. The Wood100® construction method - layers of solid wood connected with wooden dowels to thicknesses of up to 36cm - uses no glue or other chemical pollutants. The resulting indestructible solid wooden blocks are highly water resistant and perform better than any other construction method in heat insulation, fire security, radiation shielding, earthquake safety and have 100% protection against condensation and mould growth.

Temples in Japan which were built over 1600 years ago using these techniques are still standing. They have outlasted storms and earthquakes proving the effectiveness of wood to wood connections and solid wood construction.

This totally sustainable, natural resource, when used responsibly, is the best alternative to all other construction materials

Erwin Thoma, Holz100

The story behind Wood100®

Austrian Erwin Thoma, originally a forester, was disillusioned with the chemicals and artificial products used in modern home builds - the inability to recycle or dispose, their energy inefficiency and the increasing health issues occupants were experiencing. In fact it was the rapid decline in health of his son when the family moved into a new-build home that prompted his research into and ultimate belief in the traditional, natural products and techniques to build truly healthy homes.

With knowledge of solid wood buildings constructed thousands of years ago still standing in Asia and Europe and a strong environmental concern for cradle to cradle building, Erwin Thoma set out to build the healthiest home. Holz100 was the result. The patented Holz100 construction method - layers of solid wood connected with wooden dowels to thicknesses of up to 36cm - uses no glue or other chemical pollutants. The solid wood panels are assembled into interior walls, floors and ceilings, roof structures and exterior walls and results in a healthy natural shell surrounding the occupants of the home.

So strong was our belief in the philosophy behind and benefits of his product we approached Erwin and asked if we could be the first partner for Holz100 in Canada. We both import the product manufactured in their European facilities and produce Wood100® here in Canada.
