When planning a high-performance home, few decisions carry as much weight as window selection. Windows are a critical component of the building envelope, affecting everything from thermal comfort and energy bills to condensation control and long-term durability. Triple-pane windows have gained significant attention in the construction industry for their superior insulating properties, but they come […]
Windows remain one of the weakest links in a home’s thermal envelope, but decades of innovation in insulating glass technology have steadily closed the gap. From the introduction of low-emissivity coatings to the emergence of vacuum-insulated glazing, modern insulating glass units (IGUs) deliver thermal performance that would have seemed impossible just a generation ago. Understanding
Silica fume concrete is composed of cement, silica fume, fine aggregate, coarse aggregate, and water. Fresh and hardened properties of silica fume concrete is superior to conventional concrete. For
Unsound concrete can be identified through various signs such as visible cracks, micro-cracks, spalling, scaling, blisters, and delamination. Multiple factors lead to different types of damages, an
Foundation heave is the upward movement of the expansive soil layer after it is saturated with water. Controlling the signs and symptoms of foundation heave at an early stage is important to preven
Shrinkage-reducing concrete admixture promote expansion of the concrete at about the same volume that normal drying shrinkage is contracting it. The net change in length of the hardened concrete is
Shrinkage cracks in concrete occur due to change in moisture of concrete. Concrete and mortar are porous in their structure in the form of inter-molecular space. They expand when they absorb the mo
Shrinkage compensating concrete is an expansive concrete that expands by an amount equal or greater than the volume change anticipated for drying shrinkage.
Sprayed concrete is also called as gunite or shotcrete is used for rapid concrete construction. Properties, materials and applications of sprayed concrete is discussed.
When drying in a roof with ZIP System sheathing, the roof-to-wall transition areas demand the most careful attention. These junctions, where roof planes meet vertical walls, create multiple paths for moisture to infiltrate. Improperly sealed corners and wall transitions are among the most common sources of leaks in new roofs. Understanding the correct sequence for
