Lead Safe Certified Firm
Does your home contain potentially harmful lead paint?
If your home was built prior to 1978, it could contain lead paint. Starting April 2010, the Renovation, Repair and Replace (RRP) law as set forth by the EPA took effect. This rule states that any professional working on a pre-1978 home that contains lead paint will be required to follow lead safe work practices, in instances where the paint will be disturbed.
In order to comply with this new law, Portland Glass® has been certified by the EPA as a Lead Safe Certified Renovator. This means that Portland Glass® follows federal work safe lead guidelines including lead testing, containing the work area and thorough cleanup.
Selecting a company that is an EPA Certified Renovator ensures that you are choosing a company who is not only in compliance with federal law, but also is able to work with any lead paint in your home in a safe and responsible manner. Portland Glass® has locations throughout Maine, Vermont, and New Hampshire.

What do "R" and "U" value mean?
The R-value represents the resistance a material has to heat flow. R-Value measures the insulation properties of a material; the higher the R-value, the greater the resistance. Insulated glass provides a pocket of air to enhance its R-Value.
The U-Value is an insulation rating for transparent objects like glass. The term U-value is measured by the amount of heat that escapes a surface, like a wall, ceiling, or in our case, a window; the lower the U-Value, the better the insulation.
