Roof Insulation Battens

To locate the sheet insulation between the rafters while ensuring the air gap behind timber battens are first screwed to the sides of the rafters.

Roof insulation battens.

There are a lot of things that a batten roof system can do that a direct deck roof cannot. One effective way to use battens is to cross batten. Your attic ventilation and insulation will also help with summer energy efficiency. Fixing insulation between battens does not form a continuous and airtight insulation layer.

Battens elevate the roof tile off the roof deck and this ensures that water drains off the roof. In most cases the attic is ventilated and the infiltration barrier is the drywall ceiling. The air permeable insulation shall be installed directly under the air impermeable insulation.

Use battens which have been treated with preservative the simplest way is to purchase tanalised roofing battens which are usually held as standard products by most timber merchants. This involves putting down vertical battens first attaching them through the roof deck to the rafters. Counter battens are wooden strips that are installed vertically over pitched roofs to which horizontal tiling battens are attached. The batten roof can reduce heat loss and heat gain.

Roof ceiling insulation insulation in roof ceiling constructions must be placed in direct contact with the infiltration barrier. See the department of energy s doe ranges for recommended levels of insulation below. In this case the insulation must lie directly on top of the ceiling. How you install battens can affect the drainage efficiency.

This is where counter battens come in very handy. The airtwist fastener is a one piece fixing with a 7mm diameter two start helix. Typical recommendations for exterior walls are r 13 to r 23 while r 30 r 38 and r 49 are common for ceilings and attic spaces. As you already know in a pitched roof your insulation is placed under the roofing tiles.

Alternatively sufficient rigid board or sheet insulation shall be installed directly above the structural roof sheathing to maintain the monthly average temperature of the underside of the structural roof sheathing above 45 f 7 c. And then you put down horizontal battens for the roof panel attachment. For example horizontal battens run.
