Rigid polyurethane foam is suitable for a wide variety of insulation applications due to its adaptability. Due to the load-bearing, impact resistance, sealing, weight and space reduction, minimal maintenance, and durability properties of polyurethane foam insulation, it can be utilised in a variety of building types where insulation and airtightness are required. Alaska PUF is now required for a variety of applications.
High Insulating Effect
The exceptional R-value of rigid polyurethane foam, which is among the greatest of any insulating material, is well known. This makes sure that frozen or refrigerated surroundings can maintain a constant temperature or retain heat effectively.
The closed cell structure of PU insulation makes it act as an air barrier, which significantly reduces energy consumption. Unlike fibre insulation products, PU insulation does not settle and droop to disclose air holes.
High levels of both shear and compressive strength are attained when polyurethane is bonded to face materials like plywood, OSB, metal, or gypsum wallboard.
Water Vapor Transmission
The water vapour permeability of rigid polyurethane foam is poor. As a vapour barrier, polyurethane foam products with a facing like polyethylene film or aluminium foil will function to stop the growth of mould.
The permeability of rigid polyurethane foam to water vapour is minimal. Products made of polyurethane foam with an aluminium foil or polyethylene film front will act as a vapour barrier to stop the growth of mould.
Most construction facings, including foil, gypsum sheathing, plywood, fibreglass, aluminium, and OSB, are compatible with rigid polyurethane foam.
