Rigid Roof Insulation Panels

There are lots of different ways to insulate this.

Rigid roof insulation panels.

A roof over a vented unconditioned attic does not need to include any insulation. Follow with a 2x4 frame wall and insulate it with batt insulation. R tech is available with factory adhered metallic reflective facers white facers or a combination of the two. It can be applied on the roof floor and walls and it s most widely used in structural insulated panels and insulated concrete forms.

The panels provide a continuous energy efficient surface. Polyiso is an easy cost effective sustainable and energy efficient construction material. Eps is also the most inexpensive of the three types of rigid foam insulation while also meeting the required building and energy codes. How to retrofit a roof to a high performance roof with insulating sheathing above the roof deck plus cavity insulation in roof framing remove existing roofing and non adhered roof underlayment.

Apply a continuous air control membrane to existing roof sheathing or tape all joints between roof sheathing panels with an acrylic or butyl adhesive. The most versatile of the three rigid insulation options used in roof wall floor below grade structural geofoam applications used most widely in insulated concrete forms and structural insulated panels highest average r value per dollar about 4 6 r per inch costs the least while meeting or exceeding all required building. R tech rigid foam insulation. Insulated roof assemblies can be vented or unvented.

Keep in mind that any interior rigid insulating panel must be covered by a barrier. R tech panels are an engineered rigid insulation consisting of a superior closed cell lightweight and resilient expanded polystyrene eps with advanced polymeric laminate facers. A common choice is drywall. With this kind of roof the insulation follows the slope of the roof.

However most cathedral ceilings and low slope flat roofs are insulated roof assemblies. Insulated foam sheets are also used as an insulated sheathing underlayment for exterior siding. There s a reason polyiso rigid foam insulation is used in more than 70 of commercial roof construction as well as in many residential builds.
