Roof Insulation Battens

This is where counter battens come in very handy.

Roof insulation battens.

As you already know in a pitched roof your insulation is placed under the roofing tiles. And then you put down horizontal battens for the roof panel attachment. Decra tile and decra shake battens installation guides comprehensive guide that demonstrates the proper installation techniques for decra tile and decra shake roofs battens. Counter battens are wooden strips that are installed vertically over pitched roofs to which horizontal tiling battens are attached.

In most cases the attic is ventilated and the infiltration barrier is the drywall ceiling. 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. How you install battens can affect the drainage efficiency. There are a lot of things that a batten roof system can do that a direct deck roof cannot.

Roof ceiling insulation insulation in roof ceiling constructions must be placed in direct contact with the infiltration barrier. Battens elevate the roof tile off the roof deck and this ensures that water drains off the roof. The batten roof can reduce heat loss and heat gain. See the department of energy s doe ranges for recommended levels of insulation below.

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. For example horizontal battens run. Insulation can be added between the layers of the roof the batten and the external skin of the roof to increase energy efficiency. This involves putting down vertical battens first attaching them through the roof deck to the rafters.

In this case the insulation must lie directly on top of the ceiling. If water goes through it well it s not much use to you anymore. 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. Fixing insulation between battens does not form a continuous and airtight insulation layer.

The airtwist fastener is a one piece fixing with a 7mm diameter two start helix. The air permeable insulation shall be installed directly under the air impermeable insulation. 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.
