About KNM
A window and door manufacturer in Pyle since 1995
K.N.M. Limited was incorporated in November 1995 and has made PVCu and aluminium windows and doors on Village Farm Industrial Estate, Pyle, ever since. We fabricate VEKA and Smart Systems profiles for the trade and for homeowners across South Wales.
KNM is a manufacturer first. Every frame we sell is cut, welded, reinforced, glazed and hardware-fitted at our own factory in Pyle, Bridgend, by people who have been doing it for years.
We began as a PVCu fabricator making windows, doors and conservatory frames for local installers, and added aluminium bifolding and sliding doors as demand for them grew. Today the range is deliberately focused: the VEKA M70 window and Imagine vertical slider and patio door in PVCu, and the Smart Visofold bifold and Visoglide sliding door in aluminium. Fewer systems, made well, specified properly.
Two kinds of customer keep the factory busy. Trade customers, installers, builders and developers, send us sizes and specifications and receive a written quotation and finished frames. Homeowners in Bridgend and the surrounding areas ask us to survey, manufacture and install, and deal directly with the people who make their windows.
Our prices are consistently competitive all year round. We do not run sales or special offers; we give our best price the first time.

What customers say
“KNM were recommended to us so I thought I'd visit their office in Pyle to get a quote. I was shown around the factory which looked impressive and well organised - a good start. Their quote was competitive and I got a good feeling so we went with them. We weren't disappointed. Tony and John worked hard, were professional and cleaned up as they went along. We are very pleased with the windows, one of which is 4.9m in width. The windows are of a high quality, sturdy construction and we would definitely recommend KNM, they ticked all the boxes for us.”
“I would just like to say thank you for fabricating our latest job order. The customer was so impressed with the quality, thanks again for speeding it through and delivering on time.”
“Really pleased with our new composite door with side panels and window. The product and workmanship is first class. Nothing was too much trouble for this company. From initial enquiry to installation everything was dealt with in a friendly and professional manner.”
“Exceptional customer service again today. Came out within hours of my call to fix front door lock and help me out of a really difficult situation. I really appreciate the professional attitude, and immediate response. The windows and doors you fitted several years ago still look stunning. Great company.”
