There are three categories of roof insulation.
Rigid foam roofing system.
The purpose of the requirement that rigid foam installed above roof sheathing meet certain minimum r values is to ensure that the roof sheathing stays warm enough during the winter to avoid moisture accumulation and possible sheathing rot.
Depending on the type of roofing system chosen eps insulation is available in both faced and unfaced rigid foam.
Rigid board non rigid batt blanket or loose fiber and sprayed polyurethane foam.
The panels need to fit together tightly to help prevent warm air from leaving the top of the building.
Easily installed with mechanical fasteners hot asphalt or loose laid in a ballasted system.
Install nailbase for cladding.
Cost can be escalated and the roof drains may be overloaded.
The dura foam roof system has a rigid and durable surface that you can walk on.
A thick typically 1 5 thick closed cell polyurethane waterproofing barrier seals the roof against leaks.
This foam is applied over the top of the membrane that came down from the roof deck catching the wall control layers.
Prozone 365 has been formulated to spray at 2 8 pcf depending on lift thickness.
Benefits of energyguard tapered polyiso foam roof insulation include.
After the roof deck is prepared the rigid foam boards need to be cut to size to fit snugly together on your roof.
Rigid boards are typically used in low slope assemblies.
Prozone 365 is a two component hfc 365 227 blown all pmdi based spray polyurethane foam system designed for use as a self adhering seamless high insulating spray applied rigid polyurethane foam roofing system.
Rigid insulation layers exterior to existing roof sheathing must provide sufficient thermal insulation r value to control condensation risk see climate specific guidance.
Extra long fasteners will also increase the cost of the tapered roof.
Properly designed and installed energyguard tapered polyiso insulation systems virtually eliminate ponding water.
Spray polyurethane foam spf is the only roofing material that has no seams.
Rigid foam is produced in various size panels 4 ft x 8 ft 4ft x 4ft etc.
On the gable ends this was pretty easy.
Prozone 365 will be available in multiple speeds for use in varying temperature conditions.
Foam roofs are lightweight durable and seamless.
This fully adhered self flashing system is seamless and seals all penetrations with no joints or fasteners.
Carlisle roof foam and coatings spray foam roof system is a spray in place insulation made of rigid closed cell polyurethane foam spf.
One of the keys to over roofing is to tie the air control layer of the roof assembly to the air control layer of the wall assembly.
