Why Basement Insulation Starts with Water Management Insulating a basement is one of the most effective ways to improve a home’s energy efficiency, comfort, and durability. However, the process must begin with a thorough assessment of water infiltration. Applying insulation to a damp basement wall traps moisture against the structure, leading to mold growth, rot, […]
The foundation slab is one of the most critical components in a Passive House building. Unlike conventional construction, where slab insulation is often an afterthought, Passive House standards demand a superinsulated slab assembly that achieves R-values of 40 to 60 or higher. This level of insulation dramatically reduces heat loss through the floor, eliminates cold
Insulating a floor over a crawlspace presents unique challenges that distinguish it from standard wall or attic insulation. The space is confined, often damp, and subject to temperature extremes that can compromise both the insulation’s performance and the home’s indoor air quality. A properly insulated crawlspace floor assembly must manage heat flow, moisture migration, air
Cutting fiberglass batts accurately is one of the most important skills for achieving a high-performance thermal envelope in residential construction. Poorly cut batts leave gaps that reduce effective R-value and create pathways for air leakage, undermining the entire insulation investment. Whether you are a professional insulator or a dedicated DIY homeowner, mastering batt cutting techniques
When insulating a home, few tasks are as repetitive and time-consuming as cutting fiberglass batts to fit odd-shaped stud bays. Whether you are working around electrical outlets, plumbing pipes, or irregular framing, knowing how to cut insulation batts accurately can make the difference between a high-performance thermal envelope and a leaky, uncomfortable home. For a
Improving energy efficiency starts at the thermal boundary between your garage and living space. The garage-to-house wall is often underinsulated, leading to heat loss and comfort issues. Installing exterior insulation on this wall reduces heat loss while improving air sealing, moisture control, and fire safety. This guide covers the best practices, material choices, and methods
Learn how to retrofit insulation on older concrete block and cinder block wall homes. This technical guide covers exterior rigid foam insulation, window placement, crawlspace conditioning, and moisture management strategies.
Old cottages possess a charm and character that modern homes often lack, but they also come with significant energy efficiency challenges. Many historic cottages were built without exterior wall sheathing, with clapboard siding nailed directly to the studs. This construction method, while common in older homes, creates unique difficulties when it comes to adding insulation.
What Is a Ventilated Rainscreen and Why Does It Matter? A ventilated rainscreen creates a continuous air cavity between the exterior cladding and the weather resistive barrier. This gap, typically 3/8 in. to 3/4 in. deep, allows water that gets past the siding to drain freely and air to circulate behind the cladding. Without a
Learn five proven methods for properly insulating a low-slope shed roof, including vented and unvented approaches, rigid foam, spray foam, and cellulose options to maximize energy efficiency and prevent moisture problems.
