Thermal & Moisture Control

Edge-Y Solution

Thermolite U-Max glazing panels increase R-values by 100% to 200% vs. standard 1-in. infill panels by adding a rabbet edge that boosts insulation on the interior face of the panel. Systems can be specified with up to a 3.5-in. overall thickness.

Portland Rain and 22 Stories

Portland, Oregon’s rainy climate can be a dicey proposition during construction, yet an innovative barrier system answered the call when it came to preventing weather delays that could impact project scheduling. A city known for constant rains, dramatic shifts in climate throughout the year and perpetual moisture, Portland, Oregon provides unique challenges for any construction project. When Hoyt Realty Group hired Bora Architects to design the expansive, 246-ft. tall Block 20 Condominium Tower in downtown Portland, it was clear that novel solutions would be needed if the project was to be completed on time and within budget.

Get on a Drainage Roll

The promise of ventilated façades enabled by rainscreen technology to promote drainage and drying of wall assemblies is a powerful one, but it helps to know a little something about the not-so-sexy elements underneath. A tangled filament nylon core drainage mat, Sto’s DrainScreen is for use in above-grade vertical wall assemblies intended to lay beneath stucco, stone, siding and thin brick veneer. Easy to roll onto walls, water vapor moves freely through the mat layer to keep things dry and prevent water damage to façade materials.
