Not really. There are as many warranties as there are window manufacturers. Some brand name factory warranties cover just the sash and frame. The rest is left up to the local fabricator who may or may not cover it. Your warranty is only as good as the company behind it. With Alside, your unit is warranted from the extrusion and parts to the glass and construction by our Lifetime Limited Warranty*, with transferability provisions. It's one of the most comprehensive available, just what you'd expect from an industry leader.
