Viking Timber Frame Passive houses are manufactured off-site in our Irish Timber Frame factory to high quality control standards. The finished Timber frame house walls arrive on site pre insulated with factory blown Cellulose Insulation, with triple glazed Passive House windows installed and with the electric cables in the walls. All inner wall and roof surfaces of the Timber frame house are pre-finished with ready to paint Fermacell boards, so no wet trades are required to finish the Timber frame walls. Finishing the Timber Frame house in the factory has many advantages over the traditional methods and the quality of our finished Timber Frame house in terms of performance is second to none. From our Irish base we are now delivering to the market, Guaranteed Irish Passive Timber Frame houses.

The Viking Serenata House (below) and the Viking Tranquility (above) timber frame houses are available for €240k plus Vat inc HRV, passive windows and passive foundations.

Plans

Most Irish Timber Frame house companies put OSB on the outside of the frames locking in moisture and preventing the frames from breathing. This causes moisture build up in the frames reducing the effect of the insulation and causing wet-rot.

We put taped and jointed OSB on the inside of our timber frame houses to make them airtight. This allows the frames to breathe/dry out to the outside. Our timber frame house twin-wall build system totally eliminates Cold Bridging.

Our standard 300mm Timber Frame house twin-wall is insulated with dense Cellulose insulation (65kg/m2) and 50mm Wood fibreboard windbreaking insulation externally. This gives an overall wall thickness of 350mm. Our wall build up has achieved a U-value of 0.102 from the Passive House Institute and is Cold Bridge free. Our Timber Frame house walls have a Decrement Degree of over 12 hours giving the house a very high thermal mass and excellent heat retention. This Timber Frame wall-build up is designed to hold onto heat for a long time when you turn off the heat and to minimise daily temperature fluctuation, Fermacell absorbs noise, regulates humidity internally and is impact resistant.

Our silent Timber frame floors are 35% quieter than standard concrete floors. This is achieved by putting soft acoustic materials between the hard materials.
