various types of attic insulation

When we talk about the attic insulation,the R value of the insulation material should be known. The R value depends on thickness and density of the insulation material.If you are using multi-layered insulation material , you must consider the thickness and density of each and every layer.R-value chosen depends on climatic conditions and the type of heating and cooling systems that we required.Some of the insulation materials used for attic insulation as follows;

1. Sawdust / wood shavings / wood chips

Saw dust and wood shavings and wood chips also can be used as insulation materials. But it has its own limitations. Subject to infestation and pyrolysis due to heat. For remedial solution they use percentage lime .

2. Cellulose or vermiculite loose filling

Always loose filling is recommended for this type of cellulose and vermiculite insulation materials , because of the irregular joist spacing and lighting or other type of obstruction.

3. Fiber glass or mineral wool rolls usage

There are two types of density available in fiber glass or mineral wool rolls. This type of material is mostly preferred , because use friendly and easy to replace.

Recommended R- value can be attained by calculating the requirement of insulation. This may vary depends on building and place.In general , recommended R-value for old buildings is around 38 and for new buildings between 45- 50.
