Insulation




When it comes to making home climates more comfortable, saving energy, saving money and reducing CO2 emissions, the adage is "Insulate, Insulate, Insulate" and it was adopted early in this household. Why add heat if it is simply going to leak away?

Our program of insulation began in 1996 with the replacement of the old metal "Crittall" windows with double glazed wood-framed windows. For financing reasons, it took 3 years to be be able to afford the replacement of all 13 windows. Now we believe we have maximised the whole house insulation and we are pleased at how comfortable we are and how modest our heating bills are. However there is always scope for upgrading the existing.

The following are the insulation initiatives we have undertaken since 1995, in reverse chronological order:

Supplementary insulation between and around the rigid Celotex panels to eliminate small gaps and draughts.

The house loft is now typically 7 ° C warmer than the air outside.
