They say that “the future arrives first” in California—and its Title 24 codes are indeed propelling America toward a Zero Net Energy future. Designing and building high-performance roofs and attics will take unprecedented teamwork between architects, specifiers, contractors and HVAC professionals.
Here are some of the issues that they’ll jointly be focusing on:
Energy efficiency – To drive Home Energy Rating System (HERS) scores lower each year, there’s an increased emphasis on installing radiant barrier sheathing to keep solar heat in the roof panel from penetrating into a home’s attic. Products like LP® TechShield® Radiant Barrier Sheathing block up to 97% of the incoming heat, reducing attic temperature by up to 30° F. In addition, more builders are now placing ducts and HVAC equipment inside the home’s conditioned space as a strategy for achieving Zero Net Energy goals.
Proven warranties – Roofing professionals are looking for strong, long-term warranties, like the 20-year transferable limited warranty offered on LP TechShield sheathing.
Easy workability – Builders prefer roofing and attic products that install easily, with no additional tools or specialty labor required.
Moisture control – Moisture can damage a home’s building envelope so more specifiers are choosing products like LP TechShield sheathing, which features patented technology that allows the panel to dry more quickly during construction and allows for moisture evaporation.
Roofs are one of the largest parts of a home’s building envelope, yet they often get less attention than windows and walls. That’s why we’re seeing closer collaboration between architects, roofing specifiers, builders and HVAC specialists. Designing high-performance roofs and attics will play an essential role in meeting tomorrow’s rigorous energy codes.
Big builder market share has doubled in the last 25 years and now represents about 50 percent of housing starts nationwide – and even 75 percent in some major metro areas. These mega-builders have huge budgets for both land development and marketing. It’s increasingly difficult for small and medium-sized builders to compete, but LP is committed to helping them prosper.Continue Reading
To better serve its customers in areas of order accuracy and delivery predictability, LP has set some of the industry’s most aspirational supply chain goals. Senior leaders meet regularly with experts at Gartner, arguably the nation’s best consulting firm in the realm of supply chain optimization. The aim is to apply best practices in procurement, logistics and working capital across more than $1 billion of addressable spend.
For weather-resistant barriers (WRBs), ASTM has developed rigorous tests for water resistance and water penetration, plus an air barrier assembly test. But an equally important test is ASTM E96, which measures water vapor permeability over a 24-hour period.
When people talk about home “affordability” it boils down to one number: the asking price. But home “attainability” is a more complex equation. Attainability refers to a prospective buyer’s ability to find an entry-level home (no easy task these days), obtain a loan and pay for 30 years of ancillary costs like utilities, maintenance and insurance.
