Insulation
Ensuring your business premises are well insulated is a sound investment, especially if you’re based in small non-specialised buildings.
Well-insulated buildings require less energy to maintain comfortable working temperatures, as well as being healthier environments for your staff.
Low cost actions
Low-cost measures you can take to improve insulation include:
- If there isn’t any ceiling insulation, install some - the current standard is R 2.6
- Install under-floor insulation
- Draught-proof external doors and windows
- Weatherproof your building by filling gaps around pipes entering the walls
- Even if your electric hot water cylinder is a standard A Grade type, cover it with a hot water cylinder wrap
- Wrap the first couple of metres of hot water pipe from the cylinder, any high-use hot water pipes and external hot water pipes with pipe ‘lagging’.
Large or specialised premises
Larger buildings or those with specialised heating and cooling requirements such as data processing centres or coldstores will need individual consideration. Insulation has to be considered in the wider context of the building envelope and factors such as thermal mass and orientation of glazing, and internal heat load.
