Why Thermotech?
Revolutionizing Building Design:
- Super energy efficient windows are changing the way buildings are designed
- Specifically, incorporating energy efficient windows allows the designer to:
Maximize Window Design Freedom
- As you can see from the graph below Thermotech's insulated fiberglass windows have unmatched energy efficiency
Energy Ratings of Typical Casement Windows
- Unmatched energy efficiency means Thermotech's fiberglass windows provide superior draft protection, giving designers new design freedom
- Views can be enjoyed wherever they are available without causing uncomfortable drafts.
- Conventional windows are often drafty for two reasons.
- Firstly they leak air.
- Inherent stability of fiberglass frames means that they stay ‘shop floor' tight in the coldest weather
- Secondly they have convective drafts – poorly insulating frames and glazing of conventional windows can cause cold air to cascade down the room-side face of the glass
- The dramatically warmer frame and glazing of Thermotech's Fiberglass windows stay warmer, providing maximum protection against convective drafts
- Good windows mean that brighter building interiors are possible with more and larger windows, they can now be comfortable too.

Heat Your House With The Sun:
- Thermotech's fiberglass windows make it easy to capture free heat from the sun by overcoming the two main drawbacks of passive solar heating,
- Oversized windows cause excessive temperature swings
- The highly insulating glazing used in Thermotech's windows minimizes temperature swings by reducing both excessive gains and losses.
- Southern orientation limits applicability
- Thermotech's Fiberglass windows are so efficient that they don't need a primarily southern orientation to dramatically reduce heating bills.
- Graph below shows, using energy efficient fiberglass windows contributes four times as much passive solar heat as southern orientation alone

Improve Indoor Air Quality:
- Condensation induced mold growth is often a hallmark of conventional windows.
- Mould spores can cause asthma and other serious health problems.
- Thermotech's fiberglass windows' insulated frame and sash and SuperSpacer TM are significantly warmer than other windows, offering more protection against condensation than other windows.
- Maximum condensation protection means maximum health protection.

Shrink Your Heating System:
- Fiberglass windows reduce heat loss and increase comfort so much, that heating systems in houses can be totally rethought.
- With less heat loss, a smaller furnace or boiler and distribution system can be used.
- With warmer windows, registers and radiators can be moved away from windows.
- Shortening duct and pipe runs increases system efficiency, while decreasing installation costs (as well as adding flexibility for furniture placement).
- As the graph below shows, the savings of a properly optimized mechanical system for a 2150 sq.ft super energy efficient house could be as much as $3,900.
