## What is a tapered roofing system?

A tapered roof system is where the slope or ‘pitch’ of a roof is formed by insulation easily allowing water to flow into a drainage system. Tapered roof systems are also know as Tapered Roof Insulation.

## What is a tapered insulation system?

A tapered roof system is where the slope or ‘pitch’ of the roof is formed by the insulation itself, to allow water to drain off.

What is tapered insulation made of?

Tapered polyisocyanurate roof insulation or tapered iso for short, is made from the same ridge foam material that normal polyiso roof insulation is made from. Regular iso board comes in flat sheets and in several different thicknesses.

Is tapered insulation more expensive?

Finally, tapered insulation is a more cost-effective choice in most cases because you won’t need a structural fall. This reduces the overall cost of the roof if you install the insulation along with a roof replacement (or a new build), and it reduces labour costs at the same time.

### How does tapered insulation work?

Therefore, the tapered insulation starts on a dead level surface with a low point that is in a drain line. The slope goes from that point to a high point either at the roof perimeter or at a point between two drain lines.

### How do you measure tapered insulation?

How to Calculate Tapered Insulation

1. Measure the width of the roof with the tape measure.
2. Measure the length of the roof with the tape measure.
3. Multiply the width of the roof by the length of the roof to find the square footage.
4. Contact the architect who designed the building and ask for the insulation plans.

How thick is tapered insulation?

The minimum manufactured thickness of tapered polyiso board at its low edge is 1/2” and the maximum thickness of a single layer of board is 4”.

How do you calculate tapered ISO?

## What is the cheapest roof insulation?

1. Fibreglass insulation. Glass wool is one of the most common insulation materials for roofs. It is lightweight, has a good insulation value and is quite cheap as well.

## What is the cheapest way to insulate a roof?

Batt insulation Perhaps the most common type of roof and attic insulation is batt blanket insulation. Though mineral wool insulation batts are making a comeback, these rolls are typically made of fiberglass and are one of the least expensive insulation materials.

How do you find the R value of tapered insulation?

Letting H equal the thickness (or R-value) at the high point of tapered insulation and L equal the thickness (or R-value) at the low point of tapered insulation, this assumed average thickness (or R-value) is (H + L)/2.

What is the slope on tapered insulation?

The standard slopes for tapered insulation are 1/8 inch, 1/4 inch and 1/2 inch per foot to accommodate specific project requirements.
