At Boston Trade Frames, we’re a family-run business passionate about providing high-performance products. We take pride in manufacturing our own uPVC windows using the 70mm Kömmerling system. But that’s not all! We also supply and install a wide range of other uPVC windows in various styles, from classic casement windows to modern sliding sash, flush sash, and elegant French windows.
Contact UsuPVC's inherent durability makes it a weatherproof and yet low-maintenance window material.
Compared to other window materials like aluminium or timber, uPVC window frames offer a budget-friendly option without compromising on quality.
The inherent insulating properties of uPVC create exceptional thermal efficiency in uPVC windows, potentially reducing energy bills.
As well as thermal insulation, uPVC helps to provide soundproofing for a quieter home environment.
Our skilled team manufactures most of our uPVC windows in-house with the 70mm Kömmerling system; any not crafted by us are from industry-leading suppliers we’ve partnered with for years.
Our expert family-run team is on hand to offer advice and answer any questions you may have throughout the entire process.
