-:{{hilite | In warm seasons, the roof surface may reach temperatures higher than 85°C (185°F), affecting the performance and stability of some insulation. Consequently, the requirement which limits panel size in single-layer applications ensures that inevitable gaps between adjacent panels are kept to a minimum.  Combining insulation types in a ''roof system'' may help mitigate these temperature swings and the consequence of thermal contraction. The ''Design Authority'' therefore must consider these variables when specifying materials and their installation. || 2023-June-16 }}

-:{{hilite | While multi-layering insulation is required when the cumulative thermal resistance of all insulation exceeds RSI-2.64 (R-15), it is important to note that most insulation types naturally experience dimensional change in all 3 planes as outside temperatures and sun exposure change throughout the day (mineral fibre insulation being the general exception).  The degree of expansion or contraction directly corresponds with the thickness of the panel; the greater the thickness and panel size, the larger the movement.  Considerable movement may create unexpected issues with the roof; shrinkage and resulting gaps between insulation panels may introduce thermal loss, and movement that telegraphs to the supporting roof surface may produce membrane wrinkling.    To reduce the consequences of thermal movement, the ''Design Authority'' should consider specifying maximum layer thickness; any leaks attributed to ''roof system'' movement are excluded from coverage under a '''''RoofStar Guarantee'''''|| 2025-October-25}}.

-:{{hilite | The "Long-Term Thermal Resistance" (LTTR) measurement of closed-cell insulation materials remains the standard by which insulation performance is measured.  Published R-values should reflect the LTTR of the material.  In Canada, two principal standards apply to the accurate measurement of thermal resistance: CAN/ULC-S770 ("Standard Test Method for Determination of Long-Term Thermal Resistance of Closed-Cell Thermal Insulating Foams") and CAN/ULC-S704.1 ("Standard for Thermal Insulation, Polyurethane and Polyisocyanurate, Boards, Faced"). || 2023-June-16 }}
