<p>The heat-insulation equipment comprises insulating sections fixed to the inside of the roof rafters. These sections (15) are profiled plates fixed to the inside of the rafters (10) at the top, and with stepped overlapping edge strips (16,17) at top and bottom edges. Alternatively a groove can be formed to accommodate a slat, secured to the rafters via the insulating section, and a transverse ventilation channel can be formed in the section surface towards the rafters, together with water guide channels sloping downwards.</p> |
