Once the roof is in place, the windows and sliding patio door in the back can be installed. The Pella fiberglass windows include low-emissivity glass for greater efficiency. The fiberglass frames make them more resistant to extreme weather. The windows will not warp or rot in the heat or cold. Duane Putz of Pella describes the product features such as durability, scratch-resistance, color-matched hardware, and the Energy Star rating. He demonstrates how the upper and lower sash can be raised or lowered, providing natural ventilation. The sashes tilt inward, making it possible to clean the exterior face of the glass from the interior of the home.
With the windows in place, the addition’s interior can be dried out. The goal is to prevent mold growth problems from developing within the house while it is being built. Kurt Bolden of HydroLab explains how moisture is detected within the building materials. Moisture is the number one cause of defects within a building. Given the readings for this project, if the lumber is put behind insulation and prevented from drying, it could lead to increased risk of mold growth in the walls.
Charles Cressy of Water Out reviews the drying-out process to prevent mold growth in new structures. Dry, warm air is piped into the building and circulated throughout. The moisture trapped in the building material should become part of the air that is circulated and sucked out of the building. The Water Out trailer is typically used to dry out flooded buildings, and is capable of doing this incredibly fast.
