Pocahontas Windows and Patio Doors for Sun, Space and Quiet

Converting a Slider to French Doors

Many homeowners want the look of French patio doors in place of an old slider. Here is what is involved:

1. Confirm the rough opening size and header; a standard six-foot slider opening usually suits a pair of French doors.
2. Check that there is room inside for the doors to swing, or consider outswing doors.
3. Remove the old slider and inspect the sill and subfloor for water damage.
4. Install a sill pan, set the new unit and adjust both panels to seal evenly.
5. Finish trim inside and out.

If the swing space is tight, a hinged-look sliding door is a good compromise.

Glass for Severe Sun

For west- and south-facing glass with no shade, we recommend a high-performance low-E coating with a very low solar heat gain coefficient, ideally about 0.25 or lower. It blocks much of the sun's heat and the ultraviolet light that fades floors and furniture while keeping the view clear.

Quieting Road and Rail Noise

Sound travels through glass and through gaps. Laminated glass, panes of different thickness and tightly sealed frames reduce noise noticeably. Casement windows usually seal tighter than sliders. Careful insulation around each frame closes the air paths sound uses.

When to Expect Results

You will feel the comfort difference near the glass right away. Utility savings show up over the next full billing cycle in hot weather, depending on how much glass you replaced and how the house is oriented.
