How to Install 13.3 Corrugated Profile Roof Sheets The 13.3 corrugated profile is a classic roof sheet, first used in 1829 by Henry Robinson Palmer. It has stood the test of time and is now used across a wide variety of building applications, with increased popularity in modern domestic construction. This profile features a 20mm depth and covers 990mm in width once overlapped by two corrugations. Below is a step-by-step guide to help you correctly install this profile. Ensure the First Sheet is Square Before fixing the sheets to the roof structure, it's essential to make sure that the starting sheet is square to the roof frame. If the first sheet is not aligned properly, subsequent sheets will progressively become out of square, causing alignment issues. One way to ensure proper alignment is by measuring the distance from both sides of the sheet to the bottom roof batten or purlin. This will ensure the sheet is laid evenly. Lay the Sheets in the Correct Order Sheets should be laid from either left to right or right to left, depending on your preference or roof design. However, the underlap side of the sheet should always be positioned at the bottom, with the overlap side of the next sheet sitting on top. This arrangement ensures that the roof remains waterproof and secure. Fixing Placement Unlike box profiles and tile-effect profiles, the 13.3 corrugated profile is fixed at the crown (the high point) of the corrugation, rather than in the trough (the low point). The curved shape of the trough does not allow the washer to form a flat seal, which is why fixings are placed on the crown. As with other profiles, all fixings should be galvanized to prevent rusting, and the EPDM washers ensure a weatherproof seal. Use Stitching Screws for Overlap Areas To secure the overlapping sections of the sheets, stitching screws should be used. These screws should be placed at a minimum of 600mm intervals along the overlap and fixed directly on top of the crown of the profile. This provides additional security and stability. Fixing and Screw Spacing The number of screws used will depend on your specific requirements, but we recommend a maximum batten or purlin spacing of 1400mm. Along the roof, every other corrugation should be fixed. However, at the top and bottom battens or purlins, each corrugation should be secured with fixings for added strength and durability. Conclusion By following these installation guidelines, your 13.3 corrugated profile roof sheets will be securely and properly installed. Ensuring correct alignment, placement of fixings, and proper spacing will result in a durable and weather-resistant roof. For additional advice or support, feel free to contact our expert team.

How to Install RWA6Profile Roof Sheets   The RWA6 profile roof sheet is a versatile and industry-standard solution, featuring a 32mm depth and a 1000mm wide coverage. It is ideal for a wide range of roofing applications due to its durability and ease of installation. Below, we provide a step-by-step guide to ensure you install these sheets correctly for a long-lasting, weatherproof roof.   Start with a Square Layout Before you begin attaching the sheets to the roof structure, it is crucial to ensure the first sheet is square with the roof frame. If the initial sheet is not aligned correctly, subsequent sheets will gradually fall out of square, affecting the overall installation. To avoid this, measure the distance from the bottom roof batten or purlin to both sides of the sheet. Adjust until the distances are equal, ensuring the first sheet is properly aligned.   Lay the Sheets in the Correct Direction You can lay the sheets either from left to right or right to left, depending on your roof design. However, the key is to ensure the underlap side of each sheet is on the bottom. The next sheet should then overlap on top, ensuring a secure fit. This layering prevents water from seeping through the joints, keeping the roof waterproof.   Correct Fixing Position Contrary to what some might assume, the fixings should not be placed on the high points of the profile (also known as the crown). Instead, they should be fixed into the lower flat areas of the profile (the trough). Fixing into the trough provides a solid base for the screw and ensures that the EPDM washer seals tightly, preventing water ingress. Placing fixings on the crown can cause the metal to bend and may compromise the seal.   Use Galvanized Fixings All fixings supplied by us are galvanized to prevent rust and corrosion over time. The EPDM washers that accompany the fixings ensure a tight, weatherproof seal, with the galvanized top of the washer offering additional protection against moisture.   Stitching Screws for Overlap Areas Stitching screws should be used at the overlap areas of the sheets to further secure them. These screws should be placed at a minimum of 600mm intervals and fixed on top of the overlap's crown. This provides added stability to the roof structure and prevents any movement between overlapping sheets.   Fixing and Screw Spacing The spacing of the screws largely depends on your specific requirements, but as a general rule, we recommend a maximum batten or purlin spacing of 1400mm. Fixings should be applied in every other corrugation along the roof. However, at the top and bottom battens or purlins, every corrugation should be secured with fixings to provide additional strength at these critical points.   Conclusion Following these guidelines will help ensure your RWA6profile roof sheet installation is both efficient and effective. A square starting point, correct fixing placement, and proper spacing of both screws and sheets are essential to achieving a durable, weather-resistant roof.
