Quinnlite Passive extension
This Quinnlite Passive Extension was built in Dublin to Passive House standard using Externally Insulated Quinnlite blocks and our Passiv Slab foundation system which eliminates the wall/floor cold bridge. The roof was insulated with 300mm of Rockwool insulation and the house was made airtight by externally plastering the Quinnlite blocks.
2 FiWi HRV boxes were installed in preference to a centralised HRV system, which is way more efficient and hygienic. New triple glazed windows were installed in the complete house. The roof of the existing house was insulated with 300mm of Rockwool and the walls were externally insulated. The sewer pipe servicing the 6 neighbouring houses runs under the new extension, this was wrapped in underfloor heating pipe which will be connected to a small heat pump to heat the house in the future. The gas connection has been disconnected from the house as its no longer required.

Passive Slab
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
Cellulose Insulation
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
Insulated Concrete Forms
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
Timber Frame House
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 House
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
