Tanner Windows & Doors LLC

Energy Efficient

The goal here is to achieve the highest resistance to transmission-loss (U-value) while allowing a high level of radiation gain (Si g-value/ US solar heat gain coefficient SHGC), with summertime shading. Overall window performance needs to be U-0.14 or better and standard glass performance U-0.1 and SHGC-52% up to 64%. This needs to be achieved even in a severe Minnesota winter with little heat, that is, windows should lose less energy then they gain during the day.

Products

Since their windows and doors are still handcrafted one by one, they are offered in a variety of shapes, sizes and finishes to accommodate your most creative designs and your most discerning customers. Their product line is as follows; Vitra windows, Vitra frameless, Lauda windows, Holta windows, Brooklyn double hung windows, Raico curtain wall, Patio door, Swiss fineline and entry doors.

Shading

Low SHGC glass can be a sound strategy in most instances to gain the appropriate amount of 'free/passive' heat to a building during the wintertime. This requires the incorporation of an appropriate external shading system, which Tanner Windows and Doors offers.
