Our Composite Windows with real wood optional interior are a fraction of the cost of Renewal windows and installation. Save hundreds of dollars! Our Signature Composite windows start at a base .25 u-factor and go down to a .16 u factor for a double hung composite window. They are rock solid- our only problem with them is they are so darn heavy for the installers to carry on the job site.
What’s really fastenating is that they look exactly like wood windows but without all the problems that are associated with wood windows.
