Building guide
The Sandwich-Panel.eu building guide focuses on roofs, walls and the joints that make a building envelope work. Explore sandwich panels with different cores, PIR insulation and sheet metal roofing in their actual applications. The articles explain how to assess thermal, acoustic and fire performance against the specified product and installation assembly. They also cover weather-tightness, flashings, fixings and maintenance. Use the contents of each article to find details relevant to an industrial building, warehouse, workshop or refurbishment project. Before ordering, check the product documentation and its suitability for the design, including the connections and required performance.
Grants for replacing an asbestos roof in Poland: planning the application and the work
Removing an old asbestos roof and buying its replacement are separate expenses. A grant may cover only one of them. Before ordering roofing sheets or hiring a contractor, check what the scheme covers, the application deadline and the rules for claiming payment. Have the roof structure assessed and agree how the waste will be handled. Budget for the whole roof, including flashings, gutters and repairs to the timbers. Municipal funding in Poland often covers dismantling, collection, transport or disposal of asbestos-containing materials. Check the terms of the individual funding round to see whether new roofing is eligible and whether you can reclaim costs you have already incurred.
Passive house basics: the benefits and limits of a well-insulated building
A passive house needs little energy to maintain a comfortable indoor temperature. Its insulation, airtight envelope, windows and ventilation work together to limit heat loss. Roof insulation alone cannot deliver that performance. Junction details, solar shading and the way the systems are operated all matter. Consider these before selecting a construction method. The term passive house describes the energy performance of the whole building. Masonry, timber and steel structures can all be used, but each requires different junction details to limit thermal bridging. Choose the construction method alongside the design of the complete envelope.
Metal roof tiles or trapezoidal sheets? Choosing a covering for your roof
Metal roof tiles suit traditional houses, while trapezoidal sheets create a simpler roofline. Check the roof pitch, support spacing, protective coating and total installed cost alongside the appearance. Compare T18 and T35 profiles, cut-to-length sheets and modular panels against the same roof plan. Tile-profile sheets form regular rows like traditional roof tiles. They work particularly well with pronounced eaves, dormers or a traditional façade. Modular metal tiles come in small panels, while a cut-to-length sheet can cover a larger part of a roof slope in one piece.
Preparing a metal roof for repainting
A lasting finish on a metal roof depends on the condition of the sheet and the coating beneath it. Identify the existing finish, remove loose material and repair damaged areas before choosing a paint approved for that substrate. Check the sheets, flashings and fasteners, and trace the source of any staining. Holes, defective laps and weakened supports need repair before painting. Where corrosion is extensive, compare refurbishment with replacing the affected sheets. Have the contractor responsible for the work assess the coating, plan safe roof access and check that the forecast meets the paint system’s requirements during application and drying.
