Our energy upgrade solution was to wrap the house in 100mm Insulation wrap, fill all wall cavities with bonded beads, replace windows and doors with our new high performance windows, fitted with Energlaze Low E glass delivering an overall U-value of 1.1 and a new composite front door, secured airtightness with a U-value of 0.98.
Some upstairs rooms were particularly poorly insulated and we provided additional insulation by removing old insulation and spraying 150mm open cell foam between the batons, replacing plasterboard, tape and skimmed to secure airtightness.
In the attic, a structural steel beam just above ceiling level caused cold convection making the upstairs rooms even colder. Our solution was to install and spray the attic with open cell spray foam onto pre-fitted breather cards between the rafters and install 120mm of insulation foam. The foam insulation was also applied to the structural steel surfaces. Ventilation is delivered through soffit vents.
This recently completed home is now much warmer and more energy efficient. SEAI energy grants were approved for work.
