No metallic crockery has to be placed inside the microwave just like by mistake they get heated up, they're able to find a fire. Some people even make an effort to dry clothes in microwave, that is a very dangerous act. Sometimes you will find there's possibility of placing the toaster close to the curtains.

Awarded a UK patent, Senior’s PURe® range of energy-efficient aluminium windows and doors is the first on the UK market to benefit from an enhanced thermal barrier manufactured from expanded polyurethane foam (PUR). Traditionally used in cladding and insulation products, the innovative use of PUR as a thermal barrier in windows and doors gives the PURe ® range the potential to achieve U-values as low as 0.71W/m2 K when calculated as a commercial CEN standard window and 0.93W/m2 K when calculated as a CEN standard door.
