Metal Deck Roof With Insulation

Enjoy interior design freedom with above deck roof assemblies that allow for open interior ceilings and spaces.

Metal deck roof with insulation.

Steel deck with fully adhered single ply membrane over a cover board with xps insulation over gypsum board thermal barrier or applied directly to the metal roof deck. Specify this solution zip 8 17 mb. Get all the construction documentation you ll need in a single click. To maximize the energy efficiency of these roofs the roof structure must be properly insulated.

The right thickness would need to be calculated to move the dew point above the plywood deck where air infiltration is minimized. Metals are great material as a heat conductor. Air sealing hot roofs is critical. Vented attics have insulation installed underneath the roof deck in direct contact with the decking.

You can insulate a new or existing metal roof using a variety of different techniques. Steel deck with loosely laid single ply membrane ballasted with stone depending on need with without cover board or slip sheet xps insulation over gypsum board thermal barrier or applied directly to the metal roof deck. Because the insulation is so close to the roof and you want to avoid unwanted moisture buildup these roofs will need to be completely sealed off. Traditionally we ve insulated the roof panel to try and keep the temperature on the panel from reaching the dew point.

Acoustical metal deck is not in stock. Metal roofs are poor insulators. Ceiling insulation is then installed on the attic floor. Metal roofing is one of the most durable and long lasting roof materials on the market and can easily last for decades with little maintenance.

Metal roofs are durable and last much longer than conventional roof deck and shingle constructions but they come with a drawback. Robustness exceptional dimensional stability and rated for extreme hail rockwool stone wool insulation roof boards have meet both the fm severe hail and the ul 2218a standard for impact resistance. Cellular acoustical deck is also available in the same profiles. Custom ordered jobs only.

So when the temperature is dropping down then water will condense on the metal panel. Get all the construction documentation you ll need in a single click. In fact metal roof insulation will help your home from mainly two common yet stressing things such as loss of heat and condensation. Hsb 36 ac plb 36 ac n 24 ac pln 24 ac hsn3 ac pln3 roof decks are available as acoustical deck.

Typically this would be achieved by adding polyiso insulation above the plywood deck. Make sure there is adequate air flow from the eave vents to the attic area. Add insulation above the roof deck this approach fits current building science thinking in terms of putting the thermal control layer on the outside of the building structure. But a preinstalled membrane may be even more effective at removing condensation.

R 19 insulation is typically installed in the vented attic application.
