Chambered Hollows

Multi-chambered hollows in frame and sash create greater insulating and structural value.

Memory Seal

Where the sash meets the sill we use a superior bulb seal which acts similar to the gasket on your refrigerator, providing a tight seal against water and air infiltration. This foam seal has a memory that will keep its shape even after months of being compressed.

We chose Bruin for our window replacement job and very glad we did. They replaced all 23 windows in our house & we'd would gladly use them again for other work. Beyond the quality of the installation work, the windows are great! We are glad to be done with our old, drafty windows. The salesperson, Bill D., was very easy going & helped us chose the windows to best match the traditional style of our home. He also helped us through the process re: Mass Save, which made that aspect much easier as well. Jimmy made the window measuring process seamless. The install team also made the work go smoothly from beginning to end. They were polite, on time, thorough, flexible and cleaned up well. When we had a few questions after the job completion, they were also prompt & responsive. Thanks Bruin for doing such a great job! Andrea L.

This company did a great job weatherizing my house. All of the workers were very professional and respectful of my home. They also explained everything that they were doing in the house. I have noticed a big difference in my house since the company insulated and it is not drafty now. The insulation around the doors have also made a big difference. I would definitely recommend this company to anyone in the need of obtaining energy related services for their house.
