When designing the envelope of projects, we must pay special attention to each of the elements that comprise it, since each of these layers has specific qualities that will be decisive in the thermal behavior of our building as a whole. 

If we divide 1 m2 of our envelope by the temperature difference between its faces, we will obtain a value that corresponds to the thermal transmittance, also called U-Value. This value tells us a building's level of thermal insulation in relation to the percentage of energy that passes through it; if the resulting number is low we will have a well-isolated surface and, on the contrary, a high number alerts us of a thermally deficient surface.

CI (Continuous Insulation System) is an insulated facade system for walls and ventilated slabs that works through the superposition of 5 skins: fixation, insulation, waterproofing (open to the diffusion of the vapor and resistant to impact), and an outer cladding layer.

How are these components installed, and how do they work? Is it a system for new projects or can it be incorporated into existing buildings (retrofit)? How to design an CI correctly for my architecture project? Find these and other answers, below.

Eco-Friendly Insulation Offers Thermal Performance, Sound Absorption and Fire Resistance at the Same Time

With the aim of promoting more efficient ways to isolate and protect building envelopes, the Chilean team Rootman has developed Thermoroot; a biodegradable and 100% natural insulation made from roots without genetic modifications or chemical additives. These roots make up what the company is calling a Radicular Mattress which, in addition to thermally and acoustically insulating the walls, floors, and ceilings of buildings, it is fire resistant.
