The window style you choose for your home can make a world of difference in insulation, acoustics, and thermal performance. Awning/casement windows have an option that allows them to look either retro or modern depending on what type of sash they have- a splayed vs square one!
These high-performing options also provide a valid, complete perimeter seal around the glass member so no leaks will occur at any time. Plus, there are keyed lock capabilities, too, if desired ̶ these things mean business when it comes down right, protecting themselves from potential intruders who might want access without permission (burglars).
Despite being durable, single or, double-glazed windows offer excellent thermal insulation and acoustics while also being aesthetically pleasing.
