Superior UPVC Double Glazed Residential Windows in London

What Makes UPVC Double Glazing Appealing to Homeowners in London

With the continuing strides in industrial technology, the old idea of the double glazed window has been revived and given new qualities that have made it appealing to many homeowners because of its cost-effective features. The window is made of a UPVC frame where two panes of glass are fitted tightly and sealed, leaving a space between them. The two panes and the space between them serve as layers of insulation restricting the outward escape of heat or coldness inside your home when the weather outside is chilly or hot, respectively. At the same time, the multi-layered insulation also prevents the hot or chilly air outside from going inside your home in London
