The Krestmark Collection from Westlake Royal Window Solutions encompasses several series of windows that embrace a diversity of styles, finishes, and materials across new construction and replacement applications.

Here’s a brief overview of four Krestmark window series options:

Krestmark 200 Series Vinyl New Construction Windows
With a smooth bevel and a wood brickmould-like profile, Series 200 vinyl windows feature a clean-yet-bold look. A multi-chambered, fusion-welded, extruded-vinyl frame and sash provide stability, strength, and thermal resistance; a metal-reinforced meeting rail provides additional strength, positive locking, and reduced air infiltration; block-and-tackle balances ensure smooth operation; and tilt-in operation allows for easy cleaning.

White, pebblestone, and clay frame colors are available in single-hung, picture, horizontal slider, and architectural shapes. Glass options include argon fill, E66, and LoE E40.

Krestmark 220 Series Vinyl Replacement Windows
The replacement equivalent to the 200 Series, 220 Series windows also feature a tilt-in sash, block-and-tackle balances, metal-reinforced center bar, and multi-chambered vinyl frames. They come standard with efficient LoE E66 glass with warm edge spacers. An integrated nailing fin can be specified.

Single-hung, picture, and sliding windows are available.

Krestmark 250 Series Vinyl New Construction Windows
Like Krestmark’s other vinyl windows, the 250 Series includes fusion-welded corners and a multi-chambered, extruded-vinyl frame and sash. Available in casement (single, double, and triple), awning, and picture windows, the 250 Series adds ¾” insulated glass with warm edge spacers and multi-point locking hardware; argon fill can be specified.

Krestmark 400 Series Vinyl New Construction Windows
The most premium of the Krestmark Collection, 400 Series windows boast clean, trim, narrow lines for a look similar to expensive wood clad windows but without the maintenance. The 400 Series is primarily a new construction window but also can be used for remodeling or replacement applications. Along with the multi-chambered extruded frame and sash and fusion-welded corners of our other Krestmark vinyl windows, 400 Series units feature an integral pre-punched nailing fin for added strength, weather tightness, and ease of installation.

400 Series windows are available in single-hung, single vent slider, picture window, architectural shapes, and mulled units in white, pebblestone, and clay. They come with 5/8” insulated glass and warm edge spacers. Impact is available for coastal areas, added security, or sound dampening (series 4000).
