@Joelle43 @Malcolm238 and other readers,
We have been through the insulation process many times in our lives as spent much time with Professional Builders.
One matter to raise as a sustainable issue is the use of Scrim in older buildings and lack of Insurance cover if one still has it in one's home.
Scrim was used in earlier times because those before us had limited materials available to hold homes together and keep warm.
Back in the day people used candles and Open fires and some people, for whatever reason, didn't have a Fire screen to prevent sparks flying which caused the Scrim to catch alight.
As society has evolved so have advances of inventions, we now have fire screens to prevent the spread of sparks and fires, there's smoke alarms, Vesta / matches have been replaced with lighters amongst other changes.
It would be great if members of the Airbnb community wrote to Insurance companies to revise there long standing policies of not insuring Homes, notably places of Historic importance, simply because they have Scrim and left our ever decreasing Historic homes alone.
In regards to Added Insulation, do be mindful that if your home has Asbestos materials it is a fire retardant and provides warmth.
It is also found in flooring, walls and ornate ceilings and Theatre Curtains.
It is a naturally forming mineral that is best left alone.
One needs to also familiarise oneself with the Building Regulations at the time one's home was built as it all comes in to the equation.
Some laws change with words but remain as Status Quo.
Check if your home is facing the sun with it's windows, grab a Barometer and take the Temperature daily to see when and if it drops below the suggested indoor temperature for your area.
Be mindful also places of sleeping and the kitchen do not need to be the same temperature as living quarters because one is either standing up working or in bed so there's not the same need.
There's plenty of useful information in archive newspapers.
All the best.
