Yeager PVC Bird House Heat Shield Kit
NOTE: I am offering a budget Heat Shield Kit that uses 1/8in PVC. The kit includes 3 boards all the same size which the buyer must cut to shape.
Price: $7.50 plus $6.45 Shipping and Handling to USA (USPS Priority Mail Flat Rate Envelope)
These boards are easy to cut with a standard box cutter or regular cutting tool.
Note: I can get 2 sets into one USPS Flat Rate Envelope for $6.45.
And can get up to 10 sets into a larger Flat Rate Box for $13.45.
Here is some test data:
The above box is available from the-woodpecker. It's the (Deluxe) Model.

have evolved over thousands of years to use natural cavities in trees for
nesting. In their natural setting these nest sites have shade and the
insulation of the tree's trunk to keep the temperatures down. So we can see
that a nest box on a pole out in the open sun has neither of these. No shade
(unless you put the box under a tree) and relatively little insulation as
By putting heat shields on the boxes this makes the them more similar to a tree hole than without them.
Space age closed cell 1/8in Sintra PVC boards protect your birds from excessive heat in the summer by dissipating the sun's rays. They will not warp or crack like wood and will outlast any box you have. Especially useful for boxes mounted out in the full sun. In full sun an unprotected box can have an interior temperature of up to 13°F degrees hotter than the outside ambient temperature (depending on the color of the box). If your interior temperatures get up to 105-107 degrees inside this is the danger zone for small chicks.
(See test information below)
These boards are 1/8in thick and easy to cut with regular box cutter or similar cutting tool. This means you can save money by cutting your own shields from this kit.
Kit contains 3 (three) rectangular boards each one being 7.75 inches x 11.75 inches. Also included are 8 (eight) 5/16in high spacers for side and top boards and 4 (four) 1 inch high spacers for back shield. If you need different length spacers let me know. Exterior screws are also included.
Shield kit contains 3 shields for your nest box and everything you need to install including directions. PVC is white and can be spray painted any color you choose to match your existing box.
Typically if your boxes face north or east you will need a Top Shield, a West Shield, and a South Shield for best protection.

Please paint your boxes a light color! At an ambient temperature of only 93.4°F my weathered test box was 107.1°F inside. This temperature could kill baby birds!
There are also more tests available on youtube, just search my channel.
Lastly if you are ordering a set of heat shields please state the type of pole mounting that you have. See below photos for the two main types. Most bird boxes are either back mounted or center mounted.
