Expert guides
Ecoprofil’s expert guides help you plan an order for sandwich panels, PIR insulation or sheet metal. The cost of a finished roof, insulation layer or industrial building envelope depends on coverage, cutting losses, accessories and transport as well as the unit price. Learn how to prepare a quantity schedule, read basic specifications and compare offers for your project. The guides also cover second-grade stock, delivery inspections and preparation for installation. Start with the question you need to resolve, then check the individual product in the shop. Use the worked examples for planning and confirm the final specification against the project drawings and product documentation.
Fire safety in buildings with sandwich panels from specification to installation
Fire safety depends on choosing a panel with documented performance and installing it in the assembly covered by that documentation. The core designation and steel facings tell only part of the story. Panel joints, supports, fixings and service penetrations all play a part. Mineral wool panels are often chosen for walls with demanding fire requirements. Check the documents for the specific application in each case. The designer establishes the requirements for the building and its individual elements. An exterior cladding wall serves a different purpose from a wall separating fire compartments. The building’s function, structure and use determine the performance needed. The appropriate panel classification can therefore differ between halls and warehouses.
Choosing sandwich panels for thermal insulation and building protection
A building envelope must limit heat loss and meet the building’s safety requirements. When choosing sandwich panels, consider those two tasks together. PIR provides good thermal insulation with a relatively thin core. Mineral wool may be preferable where fire performance is a priority. Check the properties of the particular panel, the joint detail and the intended use. A heated warehouse, a cold store and a hall without continuous heating have different needs. The internal temperature and humidity, the materials stored and the requirements for the wall or roof all matter, as do wind loads and exposure to the elements. Without this information it is difficult to judge which panel suits the building.
Structural trapezoidal steel decking: choosing a profile for the loads and support spacing
Structural trapezoidal steel decking provides a lightweight load-bearing base for industrial and warehouse roofs. It covers large areas quickly, but rib depth alone will not tell you whether a sheet is suitable. Check the steel thickness, support arrangement, loads and fasteners against the design for the building in question. A photograph of a similar roof is no substitute. On an industrial roof the deck can support a vapour control layer, insulation and a waterproof covering. It transfers loads to purlins or other structural members. The deep ribs stiffen the section so the sheet can span between supports. The loads and spans it can accommodate must be established from calculations and the product documentation.
Trapezoidal steel cladding: uses, advantages and limits
Trapezoidal steel sheets can quickly enclose a roof or facade once the supporting structure is ready. The sheets are lightweight, come in a range of profiles and go on dry. T18 and T35 are common starting points when comparing options. A single steel skin provides weather protection. Any thermal insulation has to be specified separately. Select the sheet to suit the design loads and support spacing, and include the fixings, seals and flashings in the order. Between its fixing points, the sheet carries its own weight and the loads allowed for in the design. Even when used only as external cladding, its strength needs to be checked against the actual support arrangement.
Designing a passive house around the site, the building envelope and the people who live there
Passive house design starts with the site and the layout of the rooms. These decisions guide the choice of insulation, windows and building services. A compact shape helps reduce heat loss, but it also has to suit the way people live. A bungalow, a two-storey house and a home with rooms in the roof each call for a different approach. All three need continuous insulation, airtight joints and protection against overheating. Check orientation, shade and vehicle access. Large south-facing windows can admit useful winter sun and need shading in summer. Neighbouring buildings and tall trees change the amount of sunlight that reaches the house. Use the conditions on your own plot when positioning the building.
Rooftop solar in Poland: what to check about electricity use and billing before installation
The financial return on rooftop solar depends on how much electricity you use on site, when you use it and how your supplier credits exports. To assess a system, look beyond the rated output of the modules. The condition of the roof, installation costs and access for maintenance matter too. Review the electricity bills and roof covering together so you can size the system for the building. Generation may peak at midday when the house uses little electricity. The surplus goes to the grid. In the evening, you buy electricity under the terms of your contract. Multiplying the entire annual output by the retail electricity price overstates the savings if you export part of that output at a lower value.
