Our range of Triple glazed windows & doors

This industry could be described as “a mine-field” with a huge choice of glazing companies to choose from, some good, some not so good. Who should you choose for a quotation at least? At KJM we try and be different to our rivals, by firstly offering a hassle free sales service. None of the sales team are commission based, so we guarantee our “No sales pressure” or unrealistic sales discounts. Secondly we have a range of products that really does make us Hampshire’s one-stop glazing shop, all on display at our showroom in Andover. We always try and offer the best value on both our Veka, Profile 22, Residence 9 and Dempsey Beaumont products in PVCu. KJM also supply a range of hardwood & aluminium windows, doors and conservatories to enhance your home. KJM have been selected as Installer of the Year finalists on no-less than four occasions in the last five years, so you can trust that you are dealing with the right company.

Improved Security

Improved security over double glazed windows, due to the extra pane of toughened glass. Internally glazed windows offer added security and prevents the removal of the glass from the outside.

Sound Insulation

There is no major gain having triple glazing with three equal thicknesses of glass. The best solution would be with a thicker centre pane, please enquire for further information.

Heat Insulation

44mm sealed units filled with two 16mm cavities of argon gas. Argon gas is heavier than air, so acts as an insulator

Prevent Cold-Bridging

Warm edge spacer bars made from a composite material to stop the cold-bridge across the unit.

Low-emissivity Glass

Two coatings of low-emissivity glass (Low E). This is a microscopically thin coating that stops the heat from your house going outside.

Plenty of Options

Available in the Sheerline Prestige, Residence 9 and Residence 7 systems as a 44mm unit.
