Visit the U-value calculator. Keep in mind that this thickness will be specific to the product chosen and will vary depending on the product's thermal conductivity (lambda value). Products with lower thermal conductivities can typically meet the target U-value with a slimmer thickness.
How should I insulate the floor of my garage conversion? This guidance is aimed at Building Notice Applications for garage conversions on particular aspects of the Building Regulations. It is not a statement of law but is intended to help you understand the system.
Electricity/gas supply connecting Garage Conversion Insulation Requirements Regulations for Garage conversion insulation specify how much insulation is required on the garage's walls, floor, and ceiling. U-values are used to quantify insulation. The U-values of your space's walls affect how much energy is lost through them.
Good evening, I'm about to embark on a garage conversion with a small extension to the rear of the garage to match an existing rear single storey extension across the back of my house. My current conundrum is around the garage floor and meeting the required U values for BC, the garage has an exis. Table 1 - Typical target U-values for garage conversion The obvious way to reach a lower U-value is by fitting a greater thickness of insulation, but this could significantly reduce the amount of space within your converted garage.

A better option is to fit insulation materials with low thermal conductivities. The conversion of an underused garage into internal accommodation is a popular way to provide extra space within existing homes. Conversions can be a great way to provide additional living space such as a dining room, a guest bedroom, a cinema room or a utility room.
The existing external walls will require upgrading to ensure a U value of at least.35W/m2k (0.55W/m2K if cavity wall). The work necessary will depend upon the existing construction and the method of insulation you intend to use. Converting your garage and adding insulation can boost your home's value by an impressive 10 to 20%.
On average, garage conversion insulation costs between £3,000 and £7,500, depending on the garage's size. The building regulations impose minimum insulation standards for garage conversions, which are considered to be 'material alterations'. The recommended Best Practice insulation standards (maximum U-values) set out in Table 1 provide for a better overall standard of insulation, thus reducing fuel use, fuel costs and carbon dioxide emissions.
