It seems you want a heat shield that is a good thermal insulator. Touch blower? Is that something like a hair dryer, or the hand dryers found in toilets? The temperature from these should be well below 100C so they don't burn skin.
A heat shield needs to use a good thermal insulator. This is a material with low thermal conductivity (high thermal resistance). This is measured in watts/meter * degrees K. Heat flow is watts, so that is the heat flow in watts that raises the temperature by one degree after travelling through one meter of the material. The first link below shows a list of materials so you can get an idea. Note the conductivity axis scale is logarithmic. Aero-gel is almost magical as an insulator, while diamond "resists heat = not easily damaged by heat" but is very conductive (transmits heat very well). Water, ice, glass, soil, bricks are not very good insulators or conductors, while some woods and fibers are good insulators (because of the air gaps in them I think).
One approach is to use two sheets of some material with air between, just like double glaze windows. The sheet close to the heat source has to operate at a high temperature in this case, so that is one consideration. It doesn't have to be a great insulator. If it conducts heat well away from the stuff you want to shield that could help in fact. The air gap between the sheets should be vertical so cooler air can rise up between the sheets as it warms, carrying heat away. The sheets are best if they are reflective for heat. Mirrors for heat are generally polished metals or silvery rather than dark coloured. If two sheets are not enough, then more sheets with air gaps can be used. The space between the sheets should be reasonably wide, like 1cm or more if possible.
Some insulator materials that can be between the two sheets (other than air) might be the normal insulators used in housing insulation like glass wool, rock wool or sheep's wool. The sheet near the shielded object can be wood or ply or maybe some plastic. The one near the heat source can be glass, porcelain or ceramic, or some sort of building board (wall board, drywall, gyproc) using cement or plaster(gypsum plaster board without the paper on one side), and maybe wood (if it doesn't get too hot).
The shield can be L shaped with the angle pointed towards the heat source so it deflects the hot air either side of the object. A metal angle strip or long screws would suit the butt joint at right angles. A flat panel might do if large enough. Note that RTV (Silastic) is a suitable adhesive for high temperatures with some materials like glass and aluminium angle..
The second link has details about thermal conductivity. The third link is about isulation materials used in houses, and the R rating system (with tables of materials). Increasing values of R are better insulation. After reading this you may find floor/wall tiles (ceramic, cork etc), and ceiling tiles (batts) that are suitable materials. There may be some leftover around your house, or ask at a building site for a few left-overs.
