Window Replacement Using Anderson A Series

On this recent project we were hired to replace four wood casement windows that had rotted. These windows were fifteen years one-time and high quality when bought.

H2o infiltration is a major issue with homeowners. I get complaints each week most water that leaks in and around windows. Flashing'southward are transition materials that capture water and redirect information technology safely back keeping it outside the edifice.

At that place are iii reasons that contributed to the windows rotting:

1. Location:

These windows are located nether a small roof overhang with no gutters. Plus 2 roofs meet on the left side and h2o from both roofs bleed off the copper valley. [left in photo]

The rubber roof beneath the windows is very close which means in the winter these window sit in snow and lastly rain or melting snowfall draining off the roof hits the safety roof and splashes up onto the windows.

2. Window Style And Material:

The windows are made from forest which under certain conditions will somewhen rot. The window style was an Casement style. This meant that the window hinges were on the side and opened like a book swinging open up. During rainstorms when the windows were left open up the interior jamb sill would go wet and water somewhen found its manner through seams and into the business firm framing.

3. Improper Or Lack Of Flashing:

Fifteen to twenty years ago we did non have the super flexible safety flashing that is bachelor today. Today we install rubber flashing or a sill protector to protect the framing and drain the water exterior of the building.

To accost these problems we ordered vinyl clad, double insulated, maintenance free outside, Canopy windows and pvc trim and sill. The interior of the windows is forest with applied muntins glued to the glass.

Nosotros chose an Awning window considering it open from the lesser [hinged on top] This will forestall rain from getting into the edifice if the window was left open in a rainstorm.

Below is the steps we took and what we found after removing the old windows:

1. Remove the interior trim. Replacing a wood casement window

2. Remove the exterior trim

three. Remove the windows and insulation.

4. Inspect the framing for damage;

On the window nether the roof valley we found the 1/2″ plywood sheathing and several two×four vertical and horizontal studs rotted. The insulation was besides wet. We carefully removed the rot taking precautions not to disturb the safe covering membrane that overlapped the wall from below.

We were able to cutting out the rotted framing and not disturn the interior plasterboard.

6. Brand necessary repairs: Rotted casement window repaired

To make the structural repair we installed new 2×four vertical studs and sill studs. ane/ii cdx exterior grade plywood was installed to replace the rotted house wall capsule. We used 2-1/2″ and three″ screws as well every bit a cordless framing nailer to avoid dissentious the interior wall while attaching the framing and plywood. Using a hammer here may have crusade too much vibration and increased the potential for wall damage.

7. Install safe flashing:

Flashing is super important. Many times I feel that windows aren't installed correctly is from an unrealistic expectation nigh the effectiveness of siding in keeping moisture out of the wall crenel. What many window installers don't realize is that no matter how well siding is installed, moisture finds its fashion between it and the business firm wrap.

When wet ends upwards on a layer tar paper or housewrap, information technology runs down the wall. One time that moisture reaches the window,

it hands finds its way into the rough opening through even the tiniest holes or blast holes. Moisture that leaks

into a wall cavity causes mold to grow, rots the wood and attracts carpenter ants.

We used Vycor flexible rubber flashing to wink the window opening. All flashing's must overlap in order to ensure that water does not infiltrate the edifice envelope. The first layer of rubber is installed on the window sill and overlaps the rubber roofing. all subsequent layers of rubber overlap the previous.

We also installed overlapping rubber in the house corner directly beneath the roof valley. It is at this location that a deluge of

water drains during rainstorms.

8. Install the window units:

We purchased Anderson A-Series Awning windows. Similar I said earlier an awning window pen from the bottom and will not allow water into the building. these windows are vinyl clad with nailing flanges.

The windows are plumbed in the opening and also spaced evenly so the same size trim board will fit between all iv units.

9. I used my Duo-Fast cordless roofing nailer to install these windows. The Duo-Fast nailer easily inserted 1-1/2 galvanized covering nails into the holes of the nailing flange. The nailer does non damage the flange at all. this is a huge fourth dimension and free energy saver. Plus there is less banging on the firm walls with hammer.

10. Install rubber flashing over the nailing flanges:

Vycor condom flashing was installed over the bottom nailing flanges first, then the vertical flanges, followed by the elevation flanges. This creates an overlapping coverage described earlier.

xi. Install baste cap flashing on tiptop of the windows.

12. Trim out windows:

We used a pvc sill and pvc trim to wrap these windows. Forest crown molding was replaced under the sofit to friction match the existing molding. Anderson A series window
