1. Dimensions The numbers can indicate the dimensions of the seal. For instance, the first number may denote the inner diameter, the second, the outer diameter, and the third could refer to the width or height of the seal. These dimensions are critical for ensuring that the seal fits perfectly within the intended assembly, thereby maximizing effectiveness.
2. Weather Resistance T-lock shingles are designed to withstand extreme weather conditions, including heavy rain, snow, and powerful winds. Their unique overlapping design and the materials used in their construction provide excellent resistance against wind uplift, making them suitable for regions that experience frequent storms.
One of the critical functions of roofing mineral granules is to protect asphalt shingles from the harmful effects of ultraviolet (UV) rays
. The sun's rays can degrade the underlying asphalt material over time, leading to fading, brittleness, and eventual failure of the roofing system. By covering the surface of the shingles with mineral granules, manufacturers provide a barrier that reflects UV light and extends the lifespan of the roof.
