Humidity Monitors

Airtightness was introduced into Part L of the Irish Building Regulations for the first time in July 08. Irish houses are usually ventilated by holes in the wall and chimneys resulting in lots of airchanges on windy days and not enough airchanges on calm days. Ireland and England are at the top of the world's list with the highest levels of Asthma in World. A Humidity Monitor should be installed in our houses that sounds an alarm when humidity levels go over 60% warning occupants to open the windows. I found a few reasonably priced monitors from www.eurolec-instruments.com that should help improve Indoor Air Quality and reduce the risk of Asthma.

Natural building materials can also control indoor Humidity levels but non breathable dryling materials like Polyeurethene backed plasterboard have been banned in Germany as a health hazard because of the mould that grows between the insulation and the wall. When a kettle is left boiling for 5mins the steam that condenses on a cold concrete wall is enough to keep mould spores on the wall growing for 12 days.

606: Wood and material moisture meter

  • Compact accurate measurement of moisture content in wood, plaster, screed, concrete, brick etc.

  • Features hold function, self test function and display illumination.

  • Supplied with protective cap, belt case and wrist strap.

  • It can be used to check the moisture content of structural timbers in your roof and timbers that penetrate non breathable drylining to see if the moisture level is reaching the critical 18%. Structural timbers that are almost covered with non breathable insulation should also be checked for moisture overload.

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


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


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


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
