Every home must have high-quality insulation. These materials are added to walls and attics to help defend against outside temperatures. Without adequate insulation, a home can generate drafts and heating, ventilation and air conditioning systems can be overloaded to compensate for this. Each aerosol foam and rigid cardboard product will have a different R value due to the thickness of the materials and the type of foam used.
Aerosol foam typically ranges from 5.5 to 6.5, while the rigid plate ranges from 3.8 to 5.0, although additional layers of rigid cardboard may increase this number. The Gold Star Insulation team has spent many years installing new insulation in old homes and new buildings. Our team knows how to carefully remove old insulation and replace it with new materials. We can analyze your insulation needs and create a plan that will insulate your home well.
Aerosol foam is a sealing and insulation product made of two chemical liquids that create expandable polyurethane foam and is applied with a spray gun. In contrast, rigid foam is foam insulation that is converted into solid panels. Aerosol foam insulation is a sealing and insulation product made of two chemical liquids combined to create an expandable polyurethane foam. These cells make it difficult for sound and thermal energy to pass through the foam as it dries in place.
However, rigid foam is not suitable for uneven surfaces, since it usually comes in sheets or boards. The R value of rigid foam insulation also depends on the type of foam plate used, with R values ranging from 3.6 to 8.0 per inch of thickness, on average. Rigid plate insulation is a good option for wall insulation and for those who want a less expensive initial cost. Rigid foam plates are ideal for insulating basement walls, as they work well with flat, smooth blocks or concrete walls.
In addition, a coating material can also be applied to the rigid foam insulation, which can greatly affect the R value of the material. Here's a guide to everything you need to know about spray foam and rigid foam insulation: their basic concepts, R-values, advantages, disadvantages, costs and common applications. It is also often sprayed in open cavities, such as the joists of tires, attics, mezzanines and even the small cracks and corners of new buildings. As a result, rigid foam insulation provides an easier installation process than spray foam insulation because it can be installed alone without special equipment and without an extended cure period.
Inside the foam solution are small bags called “cells” that create barriers and air gaps. Rigid plate insulation is generally used as outdoor insulation for exterior walls, foundation walls, cladding and cladding of houses. The use of aerosol foam, especially closed-cell spray foam, is an excellent way to insulate and seal basement walls, as it provides a high R-value and excellent moisture resistance, as well as requiring less thickness.
