Attic & Wall Insulation

By: Fpi Solar  05/12/2011

Many homes lose 20% – 30% of their heat energy through inadequate insulation of the fabric of the building and the bulk of this is often through the attic.

Thankfully there’s a simple and inexpensive solution (in the shape of glass fibre, rock wool, cellulose etc.) but it’s surprising the number of poorly insulated attic spaces we still have.  Standard attic upgrade includes the following:-

*  Provide protective caps over any downlighters (to prevent overheating)

*  Lay 150mm glass fibre quilt between joists

*  Lay 150mm quilt across joists

*  Insulate water tanks and exposed pipework

*  Provide service walkway from access hatch to tanks

*  Insulate access hatch

Solar Hot Water Systems

In this period there will be minimal need to use back up heating (oil, gas, electricity etc.) and on sunny days water temperatures of 50°C – 60° C would not be unusual. A well designed and properly installed system will provide energy all year round, will be virtually maintenance free and have a design life of 30 years plus.



While we considered several providers we were very impressed with the knowledge and enthusiasm of Matthew Collison of FPI Solar and we accepted his competitive bid for the project. We were very impressed by how neat the work was with Matthew going to great trouble to maximise the space in our hot press once the equipment was installed.


FPI Solar - Energy Conservation

In new builds it’s relatively easy to plan for renewable energy heat sources such as geothermal or solar but in existing dwellings it’s a more expensive proposition as more work is involved. It makes sound sense in these circumstances to improve the efficiency of the existing heating system rather than replace it and installing a new boiler is often a good starting point.


Geothermal Heat Pumps for Space Heating

However it’s important to remember that for all heat pump systems one fundamental does not change: The greater the difference between the temperature of the source and the output hot water temperature, the less efficient the unit becomes. The clever thing about them is the way they use electricity to operate a compressor and refrigeration circuit to move heat from a low temperature source to a high temperature source.
