Eco-renovation and retro-fit insulation upgrade to a Harrogate property

Retro-fit insulation project Harrogate propertyWork undertaken between 2010/2011

1. Customers requirements / Job description

Property Description: A mid terrace stone property in Harrogate, built in the late 1880s - 1890s

Project type: A Retro-fit insulation project combined with essential property repairs.

The homeowner wanted to combine internal repairs with essential renovation work. With improved levels of thermal insulation the property was cold and hard to keep warm - and was suffering from damp and severe condensation. The property had previously integrated costly damp treatments that had not worked.

In order to achieve the high levels of insulation required to the walls and roof space, a detailed home survey was carried out. A specification and schedule of work was also provided by THIAS.

2. Work undertaken

The roof was stripped and re-slated using a high quality breathable membrane. Sections of the roof were insulated while the roof was exposed. The roof was also ventilated correctly to prevent condensation. A new Velux roof window was also installed to allow natural light into the loft space.

The entire ground floor of the property was insulated. New insulation was fixed beneath the floor boards. Removing the floor boards allowed these essential repairs to the floor joists and the improvement of the the sub-floor ventilation. This work was required due to a lack of air-bricks and the resulting condensation which was mistaken for rising damp.

A fully boarded out loft space was created with new floor joists and high levels of insulation installed at rafter level - giving a dry and clean space for storage and future development.

Outer walls were lined with thermal boards on a treated timber batten system. The remaining walls were re-plastered, old and perished plaster was removed from certain walls - and a specialist renovating plaster system (developed by THIAS) was used to give a dry wall. Where space was limited in certain rooms, the outer walls were lined with a thin, high performance thermal lining system. External renovation work included re-pointing and stone restoration work using traditional lime mortars.

3. Conclusion

Following completion of the Eco-renovation project to this Harrogate home: The homeowner now has a very well insulated home and can expect lower fuel bills in the future. Condensation and the problem of unsightly mould has been removed. Improved levels of ventilation to all parts of the property will prevent future damp problems re-occurring.
