Houseframing has been known for a very long time. Most of new houses in Norway and Sweden are built this way, and the technology is increasingly used in Western Europe (Germany, France, Belgium) as well. In Poland, although gaining popularity, building wooden houses is still met with social resistance. Below we present some facts & myths about houseframing.
“Ready-made wooden houses from self-supporting layer elements are not durable.” Myth!
In the last 40 years, researchers looking into this issue stated clearly that ready-made wood-frame houses do not differ in terms of durability and quality from houses made from ceramic hollow blocks, LECA concrete, or silicate bricks.
“Ready-made houses are susceptible to extreme wind.” Myth!
In Europe, no ready-made house has ever “flown”. In terms of resistance to extreme weather conditions, wood-frame houses are strictly just as good as houses built the traditional way.
“The best houses are constructed the traditional way.” Myth!
Such claims are akin to saying that cars engineered in the 1950s and ’60s are the optimal choice for the modern-day customer. It is clear that the last three decades have seen rapid progress in every field, house construction included. Every approach has its pros & cons, there is no golden mean and individual circumstances often decide how we build a house.
“A “thermos” house cannot be tight” Myth!
The exact opposite is true: the tightness of a building is elementary to its energy efficiency. We can either have a house that’s energy-efficient, or one that’s untight, with wind blowing through it. It is said that a 1mm by 1m slit worsens the energetic qualities of a house by 30-60%, depending on the direction of the wind.
“There’s no point in using a lot of thermal insulation.” Myth!
Expert engineers have known for several years a truly energy-efficient house needs 25-35cm of insulation in the walls & roof, and 15-30cm in the foundation slab. However, insulation alone is insufficient: it is important to keep thermal bridges and gaps in tightness at a minimum.
