Affordable Fiberglass Blown-in Insulation for South Texas Homes

Most existing homes in the Rio Grande Valley are under-insulated and can use anywhere from 6-12 more inches of blown-in fiberglass insulation on top of whatever insulation it currently has. The recommended minimum R-Value for ceiling insulation in the Rio Grande Valley is R-30, so it is important that your home has enough insulation to protect it from the very hot days that we are known to have here in the RGV.

At VES INSULATION, we install baffles in your attic as part of the installation process.  These baffles will help ventilate your attic and keep it cooler before we install the Blown-In Fiberglass Insulation. It is recommended to re-blow Fiberglass Insulation in your attic every 4-5 years as this kind of Insulation will settle over time and can be moved around with high winds.  Valley Energy Specialist is the ideal choice for home insulation solutions in McAllen, Weslaco, Brownsville and across South Texas.
