▶ START HERE — Kusiak Replacement Siding: Why It Matters in Northwest Indiana
Watch this short video to understand the value of replacement siding for Lake County and Porter County homeowners.
Your Old Siding Is Costing You Every Single Month

Most homeowners assume their insulation is doing its job. The truth is, it often isn’t — and your siding and wall system are a primary reason why. Northwest Indiana’s lake-effect winds are relentless. Cold air driven off Lake Michigan doesn’t just chill you on the way to your car — it infiltrates your home through every tiny crack and seam in the exterior wall system. When that happens, your insulation is fighting a war it can’t win. ⚠ BUILDING SCIENCE FACT: The average 2,500 sq ft home has more than half a mile of cracks and crevices in its wall cavities. When wind-driven air moves through those gaps, tests show it can rob your walls of up to 63% of their installed insulation value — forcing your furnace and A/C to run longer, harder, and at your expense. Old or aging siding makes this dramatically worse. Cracked, warped, or improperly sealed siding creates direct pathways for cold air in winter and hot, humid air in summer. Your HVAC system compensates — and NIPSCO sends you the bill. The good news: replacing your siding is one of the few home improvements that directly addresses energy loss from the outside in. And when done right — with the right materials and the right upgrade options — it can pay for itself month after month on your utility bill.
The DuPont™ Tyvek® Upgrade: A One-Time Opportunity

Here is something most homeowners don’t know — and most siding companies won’t tell you. When the siding comes off your home during a replacement project, you have a once-in-a-generation opportunity to wrap your entire home in DuPont™ Tyvek® House Wrap before the new siding goes on. Once your new siding is installed, that window closes. Forever.
Kusiak Construction offers DuPont™ Tyvek® House Wrap as an upgrade option on every siding replacement project. Here’s why so many Lake County and Porter County homeowners are choosing it — especially now, with NIPSCO bills hitting record highs.
✅ STOPS WIND-DRIVEN AIR INFILTRATION Tyvek creates a continuous air barrier around your home. Wind can no longer force its way into your wall cavities and rob your insulation of its effectiveness.
✅ YOUR HOME CAN BREATHE Unlike simple plastic sheeting, Tyvek’s unique non-woven structure blocks bulk water and air while allowing moisture vapor to escape — preventing mold, protecting your wall structure, and supporting healthier indoor air quality.
✅ PRESERVES YOUR INSULATION’S FULL POTENTIAL By eliminating the air movement that degrades wall insulation, Tyvek helps your existing insulation perform the way it was engineered to — reducing HVAC runtime and your monthly bill.
✅ PROTECTS AGAINST MOISTURE DAMAGE Wet insulation retains less than 40% of its effectiveness. Tyvek resists bulk water penetration, keeping your wall insulation dry and fully functional year-round.
✅ ONE-TIME UPGRADE — NEVER AVAILABLE AGAIN UNTIL SIDING IS REPLACED This is not something you can add later without another full siding project. If you’re replacing siding, now is the moment. Learn more about DuPont™ Tyvek® HomeWrap® at dupont.com/products/tyvek-homewrap
