Double Hung Windows

Innergy is the innovative, energy-efficient alternative to aluminum, with added insulating properties making it 700 times better.

As the next-generation of thermal reinforcement for the industry, Innergy is able to deliver a quantum Leap above aluminum in how windows perform.

• Better Thermal Performance

Up to 700 times better than aluminum in material comparisons.

• Better Thermal Break

Impervious to cold or heat.

• Better Protection Against Condensation

Helps prevent staining that can occur with metal reinforcements.

• Better Impact Testing

Resistance to impact versus other reinforcement products.

• Better Flexibility

Will not permanently set when impacted.

Bulb seals are seamless closed-cell compression seals that prevent water from penetrating the foam cell structure. Its extruded skin provides a unique UV resistant barrier with design features that enhance the weatherstrip’s sealing performance.

Seal woven and extruded pile weatherstripping with fin provides a very effective barrier against air, water, dust and noise, sealing against even and uneven surfaces with resistance to abrasion.

Neopor gives maximum efficiency and sustainability in building products. It is comprised of many small pockets of air within a polymer matrix containing graphite. The graphite reflects radiant heat energy like a mirror, increasing the material’s resistance to the flow of heat, or R-value. Neopor is unique because it increases R-Value as the temperature outside drops.

For homeowners looking for the absolute maximum in energy efficiency.
