Which type of window has the highest heat loss?

According to www.efficientwindows.org, single-glazed windows with clear glass allow “the highest transfer of energy (i.e., heat loss or heat gain depending on local climate conditions) while permitting the highest daylight transmission.” No wonder such windows are practically extinct in residential architecture.

What is the best floor insulation?

EPS sheets, fully known as expanded polystyrene sheets, are one of the best floor insulation materials. They are easy to install and they have a high insulation value. Insulation boards have to be fixed on an even ground and they are pressure-resistant, so the floor won’t crack or collapse.
