ppefmh	Ed	Garstin	1/1	The diagram below shows a comparison of single-glazed vs double glazed windows.		fgnjx	Loft insulation has a low thermal conductivity so the transfer of thermal energy will be significantly reduced. Loft insulation has a high thermal conductivity so the transfer of thermal energy will be significantly increased. Loft insulation has a no thermal conductivity so the transfer of thermal energy will be significantly stay the same. Loft insulation has a low thermal conductivity so the transfer of thermal energy will be significantly increased.	100%
