Designed into every Sierra is the highest degree of thermal integrity
possible. Which translates into an incredible energy efficiency up to
200% better than other greenhouse type rooms.
Here's why. Most greenhouse manufacturers start with reasonably
well-insulated designs, then put their units together with metal screws
or bolts! Each of these hundreds of fasteners conduct heat and cold
right through the so-called thermally broken frame, and hapless owners
lose money trying to stay comfortable.

Moreover if just a few of the screws or bolts are tightened too much or
too little, stresses are created in the frame and glazing which can
result in drafts or worse.
Sierra's exclusive nylon clip assembly system is proven thermally
broken. These clips enable Sierra to go together faster, more easily,
and with even pressure between the frame, gasket, and glass. The thermal
break is preserved and your heating bills will reflect it, as
demonstrated in the chart above. Heavy gauge, extruded aluminum
framework and exclusive nylon clip assembly system give you superior
thermal integrity. Extraordinary energy efficiency of up to 200% better
than other glass rooms. These features and more add up to a
better-looking, better performing room for your money. |
