Detached house, Uppsala

In Dalby-Viggeby outside of Uppsala, Schröder Fastighetsutveckling is constructing architect-designed detached houses using solid wood, employing a building technique that involves cross-laminating wood and other wall elements. The technique creates a material with a range of positive attributes such as vapour permeability, ensuring a healthy indoor climate and good energy performance thanks to the windtight nature of the elements. 

Reducing energy consumption to almost zero places demands on all parts during the renovation: air-tightness, insulation, windows, doors, and heating and ventilation systems. Schröders’ aim is to build a high-quality house that can boast high architectural quality, optimal energy performance and a sensible ecological profile. Simply put: climate-smart construction throughout. This made the PAROC WAS 35, Klimatskiva ZERO thermal insulation batt particularly suitable for the company’s new builds in Dalby-Viggeby. 

Work began at the start of September 2016 and two houses should be ready to sell in the spring.

Barn houses in Dalby perfectly suited for new smart attachment method

Building houses is a significant undertaking, especially in the cultural environment of the beautiful area surrounding Lake Mälaren. Schröder Fastighetsutveckling has chosen to build two large so-called barn houses in an old village with a distinctive linear layout. The land reforms that took place in the 19th century in Sweden saw many such villages disappear. Property owner Martin Schröder elaborates:
“There are almost no old buildings left here. We wanted it to be as uncluttered as possible, so we designed each house to incorporate the storage space and garage within the main building – just as the farmer would have had a coach house, we have a carport running through the house.”

The PAROC Klimatskiva ZERO builds on a new attachment method that was well-suited to the construction of Schröders’ barn houses.
“We wanted to use this kind of batt. For the structures of these houses, Klimatskiva ZERO was perfect. I can’t think of anything better suited. We screwed a kind of plug through the insulation and the wall behind it. Naturally, working with a solid wooden wall made the work easier.”

“It was incredibly versatile in terms of installation, and the result we achieved was fantastic. We tested it out with the first house and couldn’t find nothing bad to say: on the contrary, it was easy to work with and provides excellent energy performance. On that basis we opted to use Paroc’s Klimatskiva ZERO in the second house too.”

Horizontal façade screws bear the wind loads and angled façade screws bear the vertical load

Paroc’s original Klimatskiva thermal insulation batt is a success story, having helped many home owners install secondary insulation to reduce their energy consumption. The new Klimatskiva ZERO is a development of the product. The Klimatskiva ZERO is available in thicknesses of 150, 200 and 250 mm, and facilitates energy renovation equivalent to energy class A. The product can also be used in new builds, such as those in Uppsala. In such instances it is used as exterior insulation against a wooden base. 

What distinguishes the new attachment method is that it includes horizontal façade screws to bear the wind loads and angled façade screws to bear the vertical load of the façade. Lars-Erik Olsson, Paroc’s building insulation product manager, explains further.

“The horizontal screws also attach the insulation to the wall behind. If the number of angled façade screws is increased, the load-bearing capacity also increases. This combination ensures a highly robust design.”
“We hope that the Klimatskiva ZERO will prove to be as successful as its predecessor was,” says Lars-Erik.

Schröder Fastighetsutveckling AB found out about the Klimatskiva ZERO from one of their designers just after Paroc had sent out a newsletter about the product. This made Paroc’s Building Insulation Department, headed by Lars-Erik, doubly happy.

“Partly because it is a good reference for us, and partly because it is proof that our mailing campaigns work and are positively received. Schröder Fastighetsutveckling contacted Mikael Olofsson, our senior advisor, who was able to explain to them how the product is used and help them with dimensioning the attachment points.”
