Often asked: What Is Tapered Roof Insulation?

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 taper insulation?

Tapered SecurShield is a rigid roof insulation panel composed of a closed cell polyisocyanurate foam core laminated on-line to a premium performance coated glass facer. Features and Benefits. » Premium facer improves fire resistance, moisture resistance and. dimensional stability.

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.

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.

What is tapered rigid insulation?

Tapered rigid insulation is polyisocyanurate insulation or eps insulation custom manufactured to provide a slope. Tapered insulation aims to reduce or eliminate the problem by creating a slope toward the drains, which water will follow.

What is roof taper?

Tapered EPS insulation provides the required positive slope to drain while retaining the structural and economic advantages of a flat roof deck. It maintains long-term thermal performance, dimensional stability and consistent moisture-resistance. EPS effectively controls the transfer of heat within all roofing systems.

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”.

What is the cheapest roof 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.

Which type of loft insulation is best?

The most common form of loft insulation, this comes in rolls of rock, glass or mineral fibre (we use Earthwool by Knauf which is a really good environmentally friendly option), or else foil-backed felt. It’s generally the cheapest option and good all-purpose insulation, especially for between joists.

What are the different types of roof insulation?

Types of roof and loft insulation

  • Spray foam roof insulation.
  • Rigid insulation boards.
  • Blanket insulation (also called matting insulation)
  • Glass rock and mineral wool insulation.
  • Loose fill insulation.
  • ​ Structural insulated panels.

How do you calculate tapered roof 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 does tapered insulation work?

In theory, the surface is flat to begin with. 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.

What is XPS insulation?

Extruded polystyrene insulation or XPS Insulation is manufactured through an extrusion process. This manufacturing process involves melting together the plastic resin and other ingredients. The liquid formed is then continuously extruded through a die and expands during the cooling process.

What is DensDeck roof board?

DensDeck® Roof Board is an exceptional fire barrier, thermal barrier, coverboard and recovery board used in various commercial roofing systems. The unique construction of DensDeck Roof Board provides superior flute spanning that stiffens and provides increased foot traffic resistance to the roof deck.

What is a cover board?

A cover board is a thin substrate to which a roof membrane is adhered. However, the use of a cover board far exceeds that of a substrate — it also serves as a critical component that helps to extend the life of a roof.
