Windows influence heat flow, solar gain, air leakage, daylight, comfort and water-management details.
Understand the ratings
U-factor describes heat transfer through the window assembly; lower values generally mean less heat transfer. Solar Heat Gain Coefficient (SHGC) describes how much solar radiation enters. The appropriate balance depends on climate, orientation and shading.
Installation matters
A premium window installed poorly can still create air- and water-management problems. Rough openings, flashing, sill drainage and air sealing should connect correctly to the wall’s control layers.
Where Innotech fits
Alandsons supplies Innotech Windows for clients evaluating high-performance options. Compare the specific configuration and performance data required for the project rather than selecting by brand name alone.
Before ordering
- What U-factor and SHGC are appropriate?
- How will openings be flashed and air sealed?
- Are code and egress requirements accounted for?
- What lead times affect the schedule?
