Question
QUESTION: 1. what to use as fill between block and liner?
2. should cement blocks be filled?
3. what  temperature is too cool to set your blocks?

ANSWER: Hi Greg,

1.  You should not have any fill between the blocks and liners.  An air space of 1/2" to 4" is
   required.  Liners should be struck smooth on the inside.

2.  Cement blocks can be filled with pour-in block insulation, available from any masonry
   supply yard.

3.  Best practices state for work 40 F to 32 F (4.4 C to 0 C):
 
    a.  Do not lay masonry units having either a temperature below 20F (-6.7C) or containing
        frozen moisture, visible ice, or snow on their surface.

    b.  Remove visible ice and snow from the top surface of existing foundations and masonry
        to receive new construction. Heat these surfaces above freezing, using methods that do
        not result in damage.

    c.  Heat mixing water or sand to produce mortar between 40 F (4.4 C) and 120 F (48.9
        C).

    d.  Do not heat water or aggregates used in mortar or grout above 140 F (60 C).

    e.  Heat grout materials when their temperature is below 32 F (0 C)

QUESTION: i have a 40x50 ft  14ft high to truses and plan to put a woodfurnce in it, i wanted to do block chiney thinking its safer, frieds say go staight up from stove with single stainless steel stove pipe to thruses then tripple wall rest of way up. which way is best/

Answer
Hi Greg,

The best option for a chimney is straight up, with as much of it inside the building envelope as possible.

I would recommend a double-wall connector piping (stainless interior, black exterior), with a high-temperature residential chimney system (double wall, insulated) from the ceiling to the outside.
