MJ Custom Homes feature weathertight systems specialized to perform!


Landmark Architectural Shingles with a Limited Lifetime Warranty.  240lbs. per square!  Other manufacturers won’t tell you the weight of their shingles, but this is one of the heaviest shingles in the market, eliminating blow-offs.

The weather barrier is integrated onto the sheathing, so it doesn’t tear off or blow off, out-performing traditional sealing methods. Panels offer continuous thermal, air and moisture resistance while providing excellent strength & durability.

Icynene Spray Foam Insulation is an insulation and air barrier that seals areas against air movement.  MidAmerican Energy tells us that up to 30% of heat loss can occur if floor cavities, windows and doors are not sealed properly.  This home offers energy savings with Icynene Spray Foam insulation in all critical areas, including rim joists.

The leading manufacturer of windows and doors in the world, these 400 Series windows are rated the most durable, most weathertight and highest quality window by builders.  Perma-Shield cladding blocks the transfer of heat and cold 100 times better than aluminum cladding.

Passive Systems can help to save lives by overcoming the vacuum effect experienced by most houses by creating a pressure barrier to radon entry. The system also includes a pipe to vent radon gas safely to the outdoors.  This system can easily be converted into an active system by adding a fan to the radon vent pipe.

Fiber-cement siding is 5 times thicker than vinyl siding and is resistant to; wind, rain, hail, snow, sun, rot and termites.  Hardiplank siding also holds paint 3-4 times longer than wood siding.
