Velux GGU Roof Window Replacement

A Typical VELUX Center Pivot Roof Window Replacement.

velux ggu roof window 21953_7043The owners of this residence, built in 1982 in Morrison’s Willow Springs Country Club subdivision, were forced to replace their older GGU roof window.

The Velux GGU -PK10  is probably the most common size we replace in our metro area. It’s a fairly large window—about 3 foot by 5 foot. A size that works well with common rafter spacing.

We’re seeing more and more roof windows installed 20-30 years ago that are reaching the end of their useful lifespan. velux ggu roof window 21953_7037The roof window had survived numerous hail strikes. The wear and tear of years of use.  It finally gave up the ghost.

A typical roof window replacement proceeds just like a typical deck mount skylight.

The New Generation of Velux GGU Roof Windows.

In 2015, Velux introduced a new generation of roof windows with a significant number of improved features.

Style & Durability:

VELUX roof windows are made of an insulating timber core encased in white molded white polyurethane (PU) to give a smooth finish with no visible joints.

White PU doesn’t need any treatment or maintenance. It’s ideal for hard to reach areas.

It’s also completely moisture resistant, making it perfect for humid areas like bathrooms and kitchens.

Why a Center Pivot Roof Window?

A center-pivot roof window is easy to operate— even with furniture beneath. The innovative top control bar allows you to open, close and ventilate with ease.

You can install the window lower than an equivalent top-hung operated roof window to get an excellent view while standing and when seated.

Works well in rooms with a low ceiling or where you’d like a better view of the surroundings below.
