Final answer:
Anchoring a window unit into a masonry wall can be achieved using wood nailer strips, steel clips, powder-driven fasteners, bolts, or expansion anchors. So, options a, b, c, d, and e are correct.
Step-by-step explanation:
When anchoring a window unit into a masonry wall, typical means include wood nailer strips attached to the masonry, steel clips that are embedded in the mortar joints, Powder-driven fasteners, Bolts, and Expansion anchors. These methods provide the necessary support for window units in masonry constructions. Wood nailer strips offer a frame to attach the window, while steel clips embedded in mortar create a strong link between the masonry and the window. Powder-driven fasteners and bolts provide a direct, secure connection, and expansion anchors are designed to expand within the masonry material to ensure a solid grip.
When using these fastening methods, it's essential to consider the properties of the materials involved. For example, special steels, which are iron alloyed with other metals, are often used for their strength and resilience in construction elements like masonry nails, which need to withstand the rigors of being driven into tough materials.
