At DISK Enterprises,
we understand that energy efficiency is more
important than ever. That’s why we are continuously
looking for ways to make our windows and doors as
thermally efficient as possible. From the materials
we use and the glass packages we offer to our
dedication as an ENERGY STAR® partner,
we’ve got you covered when it comes to energy
efficiency.
Premium Vinyl
The premium vinyl used in our windows and doors is
an excellent insulator. Its thermal properties are
far superior to aluminum, steel and stainless steel.
Spacer
Systems
Most Simonton windows
and doors feature unique spacer systems. Made of
highly thermally prohibitive materials, these are
placed between the glass panes and further reduce
temperature transfer.

Intercept®
Spacer System
• Unique U-channel design
minimizes conduction for increased efficiency and
comfort.
•
Durable long-lasting design.
• U-shaped
design flexes and contracts, reducing seal failure
in the insulating glass unit.
Super
Spacer® System
• Solid
silicone foam provides superior energy efficiency.
• Does
not conduct energy as quickly as metal spacers.
• Silicone
foam is flexible and helps reduce stress cracks.
Glass Coatings
Many
Simonton windows and doors are available with Low E
glass. A transparent metallic oxide coating applied
to the glass surface allows short-wave energy to
pass through but reflects long-wave infrared energy
for greater thermal efficiency.
Gas Fill
The space inside an insulating glass unit—between
the glass panes—may be filled with Argon gas, an
odorless, non-toxic gas that is six times denser
than air. This acts as an added barrier for a higher
level of efficiency.
Laminated Glass
Some glass packages contain
laminated glass. A transparent interlayer is adhered
to a pane of glass, acting as a barrier against
energy loss, noise transmission and forced entry.
