General Information for Pet Doors for Sash Windows Sometimes a window offers the best location to install a pet door. The new Thermo Sash™II is the perfect answer. We use the same high quality pre-fabricated insulated
glass units, self-adjusting feature for 'no tools' installation and complete
weather stripping as the Thermo Panel II™ for minimum energy loss.
The most important new feature of the Thermo Sash II is the incorporation of a spring-load, 'no-tools' installation feature with a 3" adjustment range. You simply place the spring loaded end into the window track, press against the spring to position the other end in the opposite track and tighten two thumb screws with your fingers (to prevent removal by someone from outside).
The small/medium size, in both regular and electronic, uses Plexiglas flaps with built-in locks. The larger regular sizes, medium through x-large, use a separate locking cover which slides down a slot on the panel frame. These locking covers utilize a spring-loaded dead bolt lock to engage the frame and lock tightly shut. Remember that they will need enough clearance directly above the pet door to be removed and inserted. Also remember that your window track must be at least 1" wide to accept the pet door framing.
The small/medium unit incorporates a '4-way' locking mechanism which can be set for 'in-only' and 'out-only' as well as 'locked' and 'unlocked'. For example, if you want the pets in at night, you might set the pet door for 'in-only' in the late afternoon.
The new Ideal pet door for sash windows is now available in single pane glass at lesser cost and more limited size/adjustment range combinations than the Thermo Sash II (scroll down to see the Ideal).
This is the recently released update to the original Thermo Sash which combines the insulation benefits of dual-pane glass together with the installation ease of a 'spring-load', self-adjusting width adjustment similar to the popular Thermo Panel II. It is, without doubt, the best pet sash window pet door currently availableon the market today.
