Understanding R-value and U-value

Knowing what R-value and U-values mean is key to following energy issues and to selecting products that best suit the climate zone you are building in. R-value is essentially a product’s resistance to heat flow. Adversely, U-value measures the rate of heat transfer. This means that products with a lower U-value will be more energy efficient. It is tempting to think that these two values are direct opposites of each other, but there are some important differences to note.

Blower Door Testing 101

Building enveloped that perform poorly reduce energy efficiency, increase ROI times, and increase carbon footprints and utility bills for building owners. A blower door test can help to establish the airtightness of small to medium buildings, measure the flow of air between different areas in a building and test the airtightness of ductwork.

Why Taller Wall Panels Are The Future of Building

As the cost of building materials increase and building codes demand more effective envelopes, construction professionals are looking to taller wall sheathing to fill in the gaps. OSB wall sheathing already makes for a sustainable and cost-effective option but with taller OSB wall panels, the efficacy of the building envelope is increased by creating fewer seams while labor costs, waste and installation time are reduced.

Taller Wall Sheathing Makes Walls Stronger

Innovative manufacturers like Norbord that think outside the box have flipped the structural sheathing panels for vertical installation and increased their height. Longer wall sheathing like TallWall enables an overlap at the joists which eliminates hinge points to increase wall strength. Longer sheathing also reduces the number of seams which improves energy efficiency and makes for a stronger, smoother, flatter wall.
