I am going to build a breeze house and I want to insulate my walls with Pregymax 29,5 (13/100) for a R of 3,4 is there better on the market at the same price (10,55 € per m2) ?

The Pregymax 29.5 (which indicates a lambda of 29.5, so very interesting) is an excellent product? It is a composite plate (Insulation + BA13) ideal for thermally but also acoustically isolating an interior wall or wall provided that its surface is very regular. The equivalent plate at Placo is PSE 32 (whose lambda is slightly lower, I think the price is about the same). Both use expanded polystyrene graphite. If you found Pregymax 29.5 to 10 € ttc m2 I think it's a very good price.

Other solutions also make it possible to obtain very good insulation in small thickness. The projected polyurethane foam, for example, offers an R of 5 for a thickness of 10 cm.

For insulators in rolls or plates, they must be chosen on the basis of their coefficient of thermal resistance and other factors such as their fire resistance or nontoxicity and the PES are not the best placed.

FAQ - 💬

👉 Some newer homes may have walls built with 2x6 studs. Use R-19 or R-21 kraft-faced fiberglass insulation for two-by-six (2x6) walls. This combination ensures that the insulation is neither too loose nor too tightly packed within the walls.

👉 Our premium performance internal wall insulation can be used in a range of internal wall constructions. Internal wall insulation is applied to the internal walls of a building and can be mechanically fixed or adhesively bonded to the wall.

👉 The generally accepted cost for internal wall insulation is between £40 and £50/m2 — but it can reach over £100/m2 when a new stud wall is built. The cost of internal wall insulation will vary according to the type of insulation specified and the condition of the existing wall.

👉 Although this isn’t a budget option the department says that it can be worth the cost especially if yours is a very cold climate. Some homes were built without, or with very little, insulation in the wall cavity. In this case cavity wall insulation can bring savings as well as making your home more comfortable.
