Being fully capped, the boards are impervious to water absorption, and the timber-look cladding will stand up to all weather conditions, without requiring maintenance. NewTechWood's fluted composite wall panels can, thanks to the company's UltraShield technology, withstand even the constant humidity and salt air of coastal B.C. These panels make stunning facades and beautiful accent walls, among other applications, and are available in large strips (Belgian), and thin strips (Norwegian). The roofing sector in 2024 is characterized by an equally vigorous display of new product development. Building Products of Canada's Signature series is the latest example of the innovation and creativity that are hallmarks of the company. These shingles, launched at the end of 2023, are designed to resist even the worst weather conditions (including winds up to 135 miles per hour, with no special installation required) and come in 12 colours in Eastern Canada and 10 in the West, intended to reflect both modern and traditional aesthetics (the colours, developed by BP's Chroma Color Lab, pair well with any type of exterior finish). Elevating the colour offering is Chroma Color Lab's proprietary new Profusio design patterns that merge two shingle colours and alternates them over successive rows to create a third colour to produce a complementary or contrasting visual effect. The Signature series shingles have a high resistance to nail pullthrough and were made with BP's Weather- Tite technology, a patented roofing shingle system featuring two sealant bands. While the continuous band ensures maximum adhesion, the discontinuous dotted band increases the shingle's adhesion, keeping wind- driven rain flowing off the roof. BP Canada marketing director Nathalie Lambert says, "The Signature line brings new life and a modern twist to traditional shingles, which have barely seen a change in tints in decades. We're giving homeowners a first-of-its-kind opportunity to affix their signature to their roofs with unique natural looks that set their properties apart and blend into a home's facade like never before." Polyglass, which is part of the Mapei Group, has led the industry in the development of high-quality modified bitumen roofing and acces- sories; its APP and SBS membranes provide outstanding protection, durability, and life expectancy, and are also environmentally friendly, energy efficient, U V-resistant, and of course visually pleasing. March was a busy month for Polyglass in the U.S. with the unveiling of two new breakthrough products. PolyVap SA S is engineered for superior performance in com- mercial low-slope roofing applications and features a high-strength polypro- pylene sheet with an aggressive acrylic based adhesive on the bottom, ensur- ing a bond with most substrates. This carrier-less membrane is surfaced with a slip-resistant top surface to enhance walkability and can serve as a temporary roof for up to 180 days. PolyVap SA S is an ideal air/vapour barrier in low-slope roofing applica- tions, for use on steel, OSB, plywood, gypsum, and thermal boards. Its top surface is compatible with approved coverboards and Polytherm insula- tion, allowing for mechanical attachment or adhesion with Polyglass LRF CR (low-rise foam) adhesive. It is impermeable to air, moisture, and water, and the aggressive self-adhesive makes for exceptional wind uplift performance. Also in March, Polyglass launched Modifleece, a revolutionary fleece-backed Styrene-Butadiene-Styrene (SBS) modified bitumen roofing membrane base sheet. Designed for the use in multi-ply low-slope roofing systems, Modifleece, thanks to an innovative laminating process, integrates a specially formulated dual compound into the polyester fabric, creating a seamless bond between the two components. The self-adhered side laps are safeguarded by a protective release film; the film is removed during application to reveal the aggressive self- adhered SBS compound, ensuring watertight seams. Modifleece serves as a strong and durable waterproofing substrate for additional roofing membrane plies, ensuring long-lasting protection. It is suit- able for application directly over irregular or semi-rough substrates, including Lightweight Concrete (LWC), and as a recover option over existing modified bitumen roofing systems.
