Understanding the Elements

Air Tightness.png



Floors, walls, and ceilings are the largest source of a home’s air leakage, accounting for more than twice as much leakage as windows and doors combined.

Air constantly moves from high to low pressure, finding every penetration into and out of your home.  Proper insulation means lower utility bills and a more comfortable living space.

Noise Control.png



In the county, we love the sound of freedom as we watch that Pax. River jet fly over.  We love our neighbors and their dogs.  We love the sound of our kids practicing on the drum set their grandparents bought.  Proper insulation helps us to love these things even more as it reduces exterior and interior noise.

Moisture Control.png



Moisture in the home is everyone’s concern.  When insulating, consider adding a vapor retarder that reduces the risk of mold and mildew, while improving air quality.

  • What is capped polymer decking material?
    Capped polymer decking does not contain any wood products. Unlike composite decking, Azek Max’s Capped Polymer Decking boards are composed of a mainly - polyvinyl chloride (PVC), which is most commonly known as vinyl. The lack of wood fiber in this material makes capped polymer the superior choice for decking around water applications such as piers, boardwalks, and most commercial applications.
  • What are the benefits of Azek Max’s capped polymer decking?
    Because there is no wood fiber in the material, capped polymer decking is unbeatable in its resistance to mold and mildew, which means boards won’t rot, splinter, crack, or warp. It is extremely low maintenance with no need to sand, seal, or stain ever.
  • What is the warranty for Azek Max’s capped polymer decking?
    The fully synthetic cap and core of Azek Max’s capped polymer decking has a warranty unsurpassed by anything in the industry. Azek Max comes with a Limited Lifetime warranty against manufacturer defects, including delaminating, chipping, and splitting. Its superior resistance to weathering allows Azek Max to come with a 50 year fade and stain limited warranty.

They were very professional and timely getting us a fair estimate, getting us on the schedule, and doing a great job. Highly recommend!!! Thanks guys.
