A construction site in New England? It is a climate notorious for potentially challenging the most heavy-duty tape. Some are applied as a liquid and then they transform into a solid. Depending on their function, they are engineered accordingly. Yet when cold temperatures occur, the liquid component of the adhesive tape hardens, similar to what happens to butter in the refrigerator.
Can EPDM be Installed in Cold Weather?
Why Doesn't Adhesive Tape Stick in the Cold?
Cold temperatures change the physical properties of adhesives, sealants, primers, and coatings, and alter the handling characteristics of roofing membranes due to increased rigidity. The information in this bulletin is intended to help installers successfully apply Firestone materials in cold weather. When liquid materials are cold, their viscosity increases which may cause solvents and solids to separate. This separation can make mixing and dispensing difficult. To minimize the potential for materials cooling on the roof before application, follow these additional guidelines:. The table below shows various flash-off times associated with solvent components of Firestone adhesives, sealants, primers, and coatings. Our products may contain one or more of the solvents listed below.
Re-covering a roof in cold weather
With low temperatures, ice and snow, winter is not the ideal time to change the covering on a roof. If the work is required in any case, certain precautions must be taken, depending on the type of roofing to be repaired and whether it is made of asphalt shingles, a rubberized membrane or a multi-layer membrane. Also, they must be glued as well as nailed, because the sun is not warm enough at that time of year to activate the self-adhesive strips intended to keep them from being blown away by the wind. Rubberized membranes Rubberized membranes are made of bitumen that is modified by means such as adding rubber, giving them very great flexibility. Ceramic granules protect their upper layer from damaging ultraviolet rays.
