Bow windows and bay windows are window combinations that project outward from a home. These combinations can add space, volume and light to a room, as well as adding more personality to any home.

 

Soundproof Windows

Soundproof windows look and feel just like a storm window, but they are specifically made to reduce sound. They are often installed with your existing windows, forming a layer of protection against noise. Soundproof windows can be installed on the inside or outside of your home, soundproof windows are made to look like any other window, and can be cleaned easily. Many soundproof windows can reduce noise up to 95 percent effectively blocking the sounds of the outside world. Some soundproof window styles can serve as additional insulation, saving you on heating and cooling bills.

Glass Block

Lavitech Los Angeles Window Installation - Glass Block

Glass block windows are glass blocks that can either stand aloneas an accent window, or combined to form one large window. Sometimes frosted or forming thick, decorative glass, they work great for privacy while still allowing light to pass through. The most common areas for glass block are in the bathroom and bathroom, and in transoms and sidelights. They are even incorporated into walls of showers or bathtub enclosures.

Thermal Windows

 

Thermal windows can increase your home’s energy efficiency and decrease your heating and cooling costs significantly. Designed with two and sometimes three panes of glass stacked on top of one another in the window frame with space between that traps air between the panes and provide much better insulation than single paned windows.

Skylights

Lavitech Los Angeles Window Installation -Skylights

Skylights are a great way to add light to any area of the house that doesn’t get enough lighting. They add natural lighting, the most energy efficient way possible. They are manufactured in several different shapes, designes, styles, and colors. Skylights are designed for different roof pitches and elevations, including some of the most abstract and complex systems. Some options available are: Domed, Glass, Sloatube, Impact Approved, Architectural, Plastic Glazed, Curb Mount, Fixed or Non-Operable Skylights. Some venting options available are: manual, electric, operable, and retractable vents.

Sun-Tunnel Skylights

Sun-Tunnel Skylights are designed to be the most energy efficient skylights available. They are built with a highly-reflective tunnel that provides bright light despite long elevations or poor sun-location. Additionally, an energy saving skylight cover system is available for energy control. In the summer, this cover system reflects back solar heat and in the winter adjusts for more absorption of the sun’s rays.

Dormer Windows

Lavitech Los Angeles Window Installation - Dormer Windows

Dormers are usually built into the roof of a home that has living space close to the roof. Light and air flow are essential for the vitality and comfort of attic rooms. Dormers provide more space and dormer windows provide that light and the flow of air. Because attic rooms can be tough on a/c units, its important to circulate warm air continuously. It’s usually best that dormer windows are double-hung, meaning they open both at the top and bottom of the window frame. This creates a draft that pushes warm air out the top of the window while allowing cool air to flow throught the bottom half.

 

Don’t let your time and energy slip out of your old, drafty windows. Don’t spend your hard earned money on high heating and cooling bills caused by inefficient windows. Put an end to many of the tiring tasks of exterior home maintenance.

Leaking and cracking windows may be damaging your home

 

Your older windows may be hiding something from you. If you notice excess condensation or leaks near your windows, it may mean that moisture is getting into your walls. To ensure against dry rot and potential mold problems, new replacement windows may be the key.

Measuring Infiltration and Thermal Losses

Window heat loss may be considered as a combination of thermal and infiltration (or leakage) losses. Thermal loss occurs when energy passes directly through the materials of the window. It includes radiation and convection to the interior surfaces of the window from the room; conduction through the materials of the window; and convection and radiation from the exterior surfaces of the windows to the outdoors.

Infiltration losses are driven by wind and by differences between indoor and outdoor temperatures. They occur primarily through cracks in the sash, gaps between the sash and jamb, and gaps between the frame and rough opening.

 

We calculated thermal losses using WINDOW 4.1, a computer model developed by Lawrence Berkeley National Laboratory’s Building Technologies Program. We based our infiltration test method on ASTM E783-93, performing two air leakage tests on each window. We constructed a simple measurement device around the windows by taping a plastic sheet onto the interior trim and attaching an air hose, blower and pressure tap.

First, to test total leakage, we drew air through the window using the blower and measured the flow rate, in ft3 per minute (CFM), at various pressure differentials across the plastic sheet. Then, to test extraneous leakage, we attached a second plastic sheet to the exterior trim of the window and repeated the test. By subtracting the value obtained in the second test from that obtained in the first, we were able to estimate sash leakage.

We found that, on average, the air drawn through the windows in the study was approximately 30% cooler than the indoor air. Based on this difference, we assumed that

approximately 30% of the extraneous leakage was outdoor air coming through the rough opening.

We thus estimated total infiltration as sash leakage plus 30% of extraneous leakage. While this method was not very precise, it did allow us to estimate the relative contribution of rough opening leakage to heating load.
