We developed the "Viking Warm Stud" timber frame system by combining Alaskan and Swedish timber frame construction methods. This construction method eliminates the need for tapes or membranes and simplifies the complete Passive House construction process. The timber frame is constantly warm which keeps the timbers away from the Dew Point so they don’t need to be ventilated. The plywood outside the Timber frame becomes the air-tightness layer and the wall can breathe in and breathe out from the plywood layer. Each joint in the plywood is sealed with silicone which is sandwiched between the stud and the plywood, this forms the airtight layer. The ends of the joists are cut off where they meet the wall so the plywood can continue up and over the roof.

We can now supply and erect insulated/airtight timber frame houses and Passive Slab foundation systems for as little as £32/ft2, with wall, floor and roof U-values of 0.10W/m.K. The house consists of a 100mm stud and a 150mm roof externally air-tightened with Plywood and externally insulated with 200mm of EPS. The "Warm Stud" method eliminates airtight membranes and tapes and simplifies the air-tightening process. To finish the wall you just plasterboard the inside and plaster the EPS on the outside.
Passive Slab is Passive House certified to deliver the lowest U-value (as low as 0.08W/m.K) on the market and eliminates the critical wall-floor Cold Bridge. Read More
Ireland’s first Closed-panel timber frame Passive House was manufactured in our timber frame factory in Tipperary in 2008 and we’ve constructed over 100 Passive Houses since then. Read More
Cellulose insulation is made from recycled wood fibre, primarily newspaper. One hundred kilos of cellulose insulation contains 80 to 85 kilos of recycled newsprint. Waste disposal is a major problem for cities. Cellulose unquestionably meets all requirements for insulation specified by the guideline. Read More
ICF Insulated Concrete Forms are formwork for concrete that stay in place as permanent building insulation for energy-efficient, cast-in-place, reinforced concrete walls, floors, and roofs. The forms are interlocking modular units that are dry-stacked (without mortar) and filled with concrete. The forms lock together somewhat like Lego bricks and serve to create a form for the structural walls or floors of a building. Read More
Our Timber frame Passive Houses usually arrive on site pre-finished with Cellulose Insulation in the walls and triple glazed Passive House windows fitted. The Timber frame walls can be pre-finished internally, so no wet trades are required on site.Read More
Passive Houses are highly insulated, comfortable, cold bridge free structures that require little heating, they usually have triple glazed windows, heat recovery ventilation (HRV) and high air-tightness levels. It doesn’t cost extra to build a Passive House using our construction methods, as money saved on a complex heating system pays for better windows or extra insulation. Read More
