- to achieve temperatures high enough to facilitate cement hydration in mortar (when it's not enough just to heat the mixing water and sand)
- to protect the wall
- and to improve the comfort and efficiency of masons and tenders.
Materials commonly used in constructing enclosures include wood or steel framing elements and various plastics, such as reinforced-polyethylene, nylon, or fiberglass.When selecting an enclosure system, masonry contractors should answer the following questions:
- Are you laying a masonry veneer wall on an existing structure or laying a loadbearing masonry wall?
- What type of scaffolding are you using?
- Are you constructing a high-rise or low-rise building?
- Will the entire building be enclosed or just the work area and adjacent wall?
- How long will the enclosure remain in place?
- Do you plan to reuse the enclosure system again and again?
- Will the system need to withstand severe winds or heavy snow?
By answering these questions, a contractor can pinpoint exactly what his needs are, and can design an effective cold weather enclosure system.
