2 Rigid insulation r value

How much foam do you need? I building a new home in Ontario and will be installing hydronics in the basement floor. I will install ″ of rigid foam insulation under the slab. Question is which rigid foam insulation is best “Pink or Blue”? I’ve noticed “pink” carries a premium price to the blue.

Both have the same R value and the same compressive strength. Rigid foam can be used in walls, roofs, and foundations, for retrofits or new construction. There are three main types of rigid foam insulation : expanded polystyrene (EPS), extruded polystyrene (XPS), and. Rigid insulation is one of the best tools to reduce your energy costs.

Install it anywhere from the roof to the foundation. You can even place it under the foundation slab. They keep your home at a comfortable temperature without the need to crank your heat. It is offered in multiple thicknesses and dimensions in both square-edged and tongue-and-groove joints.

The main advantage that rigid insulation provides over other types is its higher thermal resistance, or R value. Traditional loose-fill insulation , such as fiberglass or cellulose, has an R value between R - 2. Choose insulation wisely, and consider the effect its characteristics will have on the performance of the walls. This construction uses foil-faced polyisocynaurate insulation against the concrete foundation and a 2xframed wall with R -cellulose insulation in the stud space. The slab is insulated with XPS rigid insulation under slab and the rim joist is insulated with closed cell high density spray foam insulation. When making a selection below to narrow your down,.

For example, insulating a 10-square foot wall area to R -costs about $3. R -Panel is manufactured with a closed-cell polyisocyanurate foam core bonded to fiberglass-reinforced facers and designed for use over metal, nailable and non-nailable roof decks with a variety of membrane systems. Extruded polystyrene board - 4. There are others but they are a lot less popular and pretty costly. Each type of insulation board are very different and carry different r - values and compressive strength.

So lets delve into the differences of each. The r - value of rockwool insulation and mineral wool insulation varies widely. R - value for rigid foam costs roughly $10. It really depends on what form the wool is in.

Press or formed rolls and sheets will have a different thermal resistance than loose fill type insulation. This type of rigid foam usually comes with a reflective foil facing on both sides, so it can also serve as a radiant barrier. Compatible with all types of commercial roofing systems, the lightweight, easy-to-handle insulation is especially suited for direct application on FM approved and UL classified steel roof deck assemblies. Water Absorption, ASTM C27 by volume, max.

It will absorb moisture if wet and degrade in sunlight. These products offer superior long-term thermal efficiency, fire resistance, moisture control, acoustic performance and are compatible with numerous framing systems and cladding attachment systems.

Fiberglass batts for standard ×walls are now available in low, medium, and high density products that range from R -to R -15. Find our Lowest Possible Price!

EPS and GPS insulation for many uses and applications. R means resistance to heat flow. Review the construction documents for the details describing slab insulation installation and construction techniques. Information on Construction Documents.

R -insulation (typically ¼”) thick into a 2xstud cavity that is ½” deep. That amounts to at least R -for a 3. R -for walls with 6-inch studs. To achieve this Rvalue , we recommend either rigid foam board insulation or spray foam. Reason to use rigid foam board insulation , is that its cheap? I am thinking plywood base, vapor barrier, foam board base, screwed and glued down to base.

The average cost of flat roof insulation is $0. High quality rigid foam insulation that is properly installed will greatly improve ventilation, eliminate drastic temperature fluctuations inside the home, and protect from leaks. PolyISO with 6- R value ). EnergyShield is suitable for a variety of continuous insulation (CI) applications.
