Attic Rafter Vents

Hi

Live in an old house and in the next few weeks I plan to remove all the insulation and replace with 12" (6" in joists with 6" on top but perpendicular).

Before doing that I want to put in some attic rafter vents.

Please see the following image of what I am talking about.

Attic rafter vents help maintain constant airflow from soffit vents through the attic to the ridge vent. High moisture resistance means long life performance. The attic rafter features break-resistance and lightweight rigidity for ease of installation and fits 24" rafters or snaps in half for 16" rafter spacing.

Q. Does anyone know of anywhere in Laois/Tipperary where I can purchase these? If not those locations then anywhere in Ireland?

Anyone who has used these, could you post negative/positive experience?

Thanks.

Perhaps I should have taken my time searching before posting thread - apologies.

This company is located behind the Red Cow Hotel - their number is (01) 450 2958 if anyone is interested.
Usually they sell per box (75 sheets per box) but if people require only a specific number they may have open boxes (best to ring though to confirm).
The lady I was speaking to quoted me €1.20 per sheet so do the maths for a box.

Thanks!

I have a few of these to spare. They work well in ensuring air gets through and into the attic.
