| Most people don't really understand the fabric of their buildings, and so we tend to put all the responsibility for a retrofit project onto the builder who gives the quote. It's in your interest to have some knowledge beforehand, or you could end up spending more money than necessary and/or making the wrong decisions. Lack of understanding leaves you open to unwittingly using materials that can be damaging, and require more work (and money) to put right later. | Most people don't really understand the fabric of their buildings, and so we tend to put all the responsibility for a retrofit project onto the builder who gives the quote.

| In post-war Britain, there was an explosion in products from the petrochemical industry. Pre-war, homes tended to be draughty and damp, and plastics were seen as the solution - wonder products that were light, hard-wearing and waterproof. Petrochemical-based products such as vinyl paints and wallpapers, synthetic sealants and plastic sheeting were used to waterproof our homes, creating unhealthy internal environments due to condensation and mould. The synthetic measures didn't increase the comfort of the property, and created as many problems as they solved. Trapped moisture in houses is unhealthy for people, and moisture trapped in the fabric of the building is damaging for the building itself. Breathability and ventilation are essential ingredients of the retrofit concept. Without them, a building and its inhabitants will suffer. Petrochemical-based products prevent breathability. Also, in the past we have tended to prioritise total draught exclusion without giving enough consideration to ventilation. | In post-war Britain, there was an explosion in products from the petrochemical industry.

| First, learn about the fabric of your building. Talk to people, attend a course, read books, research online, learn about what it's made of, and how you can work with that to achieve the best level of comfort. For example, if you have a stone building in a wild location, lashed by wind and rain, then make the core living area cosy, and have more active areas elsewhere. Remind yourself of the original purpose of the building and adapt your behaviour accordingly. | First, learn about the fabric of your building.
