A guide to roof insulation

by: Kirsten Land on December 18th, 2018 about Roofing Advice

With winter bearing down on us all, now may be a fine time to peek into the attic to check on your insulation.

A well-insulated roof evenly distributes warmth throughout a home, cuts down on heating costs, and prevents ice dams. Some experts have estimated that new insulation saves anywhere from 10% to 50% on heating bills. Plus, good insulation means cool air stays inside during the hot summer months.

Types of insulation

If you are not sure what you have, you can always talk to a professional, but here are some ways to identify your current insulation type.

1. Loose fill

Loose fill insulation is either spread out or blown into place. It is usually used for attics with irregular joist spacing (not 16 or 24 inches), obstructions, or to fill gaps and cover existing material. Common materials include fiberglass, cellulose, and mineral wool.

  • Fiberglass is the lightest material, but it requires a thicker layer to work properly. It’s typically yellow, white, or brown.
  • Cellulose is the most common, but it should not be allowed to absorb any moisture due to the risk of mold and mildew. Cellulose insulation tends to look gray or brown.
  • Mineral wool is naturally fire resistant, but it is more expensive. It looks gray or white and can mimic long, stringy wool.

2. Rolls

These are the thick, flexible strips of material referred to as “batts.” They work best when joist spacing is a standard width and there is plenty of headroom for the installation process. Common materials include fiberglass, cellulose, mineral wool, and cotton.

  • Fiberglass is very commonly used. It may be a mild skin and lung irritant if touched, and it does not hamper airflow as well as other materials.
  • Cellulose is treated for insect and fire resistance. However, it is not produced by all manufacturers.
  • Mineral wool is naturally fire resistant, but it is more expensive.
  • Cotton blocks airflow and sound, but it is more expensive than other options.

R-Values

R-value refers to how much is required to meet a standard level of insulation. The recommended R-value target for Oklahoma ranges from R30 to R49. This means that if a material’s R-value is three, then ten inches of insulation would be required to meet the minimum value of R30.

The manufacturer should be able to give you more information about the R-value, and so can the professional you hire to install your new insulation. If you should decide to do the installation yourself, there is much more to consider. This Old House has a helpful guide if that is the case.

Lights! Christmas! Action!

by: Kirsten Land on December 4th, 2018 about General

It’s that time of year, and the holiday season is upon us. If you haven’t already, now is the time to hang the lights, blow up the snowmen, and really show your neighbors who has the most holiday spirit! But before you get started, here are a few things to remember.

1. Measure what you need

If you are in a new home or are planning different decorations than previous years, you will want to get out a tape measure and make sure you have what is necessary to fill the space. Look at where the lights will be hung and ask yourself what kind of clips would be best.

Maybe you want to wrap a tree or bush in lights this year. A rule of thumb is 100 lights for every foot and a half of tree. So a six-foot-tall tree would need 400 lights on the strand. You could also invest in net lights for the bushes and shrubs and just drape the lights over the top.

2. Get the right color

Not all lights look the same. White LED bulbs tend to shine blue while white incandescent bulbs look more yellow. Match what you already have if you need to buy more. You can also mix the color of lights you’re hanging. For example, all the gutter lights on your home could be white icicle lights while all the trees or bushes are multicolored.

3. Safety

This is probably the most important tip. Stay safe!

  • Follow proper safety precautions when using a ladder.
  • When using lights outdoors, only use lights rated for outdoor use. It should be clearly marked on the packaging.
  • Aways use UL-approved extension cords for outdoor use. Never use any lights or cordage with fraying or exposed wires.
  • Turn off your lights during the day and when you’re out of town.

When putting your design together, go into it with a plan. Start at a focal point, like the front door or the walkway leading to it, and spread out evenly from there. Don’t forget to have fun with it!
