Opening Direction: Looking at the door outside the house, do you want it hinged on the left or the right? The two-pane can also be supplied as a French door.

From a functional perspective, R9 windows are distinguished by their nine-chamber design. This configuration ensures superior thermal performance and sound insulation, providing a high degree of comfort for homeowners. The windows are available with double or triple glazing, with triple glazed units achieving impressive U-values as low as 0.8 W/(m2k). This level of energy efficiency is particularly beneficial for homeowners looking to reduce their energy consumption and contribute to a greener future. Moreover, the robust construction of R9 windows ensures exceptional durability, promising long-lasting performance that your customers can rely on. The system can be supplied in modular kit format (please see size matrix) as well as bespoke sizes and configurations. There’s a story behind this as we had to find a solution to a problem with regard to the dimensions of a sub-cill and how to measure them. As to which is required depends on whether you’re installing an aluminium bi-folding door, sliding door or window. You also need to give consideration for the floor and wall construction and Building Regulations. It also depends on what cills are available and appropriate to the design and/or aesthetics of the building internally and externally. Aluminium Sub-Cill You say the sill was attached to the frame before fitting. If it was screwed from underneath, you will need to take the whole frame out and sort it properly.

Spruce up your Skirting Boards with this great alternative to wood and no painting required!

If it was screwed through the frame down to the sill, you may be able to remove the screws and reposition the sill, re-screw it after silicone(ing). The red section is the aluminium sub-cill with the grey section above being a typical aluminium window profile. The light blue sections are the thermally efficient barriers (thermal breaks). Cills without thermal breaks cannot be used on your home, just on some commercial type projects. The Sill is not attached to the frame at all. When I said I fitted the sill first I meant on a bed of mortar not to the frame sorry.

Dimensions: Two panes bi-fold. Min Height 2020mm Max Height 2400mm, Min Width 1500mm, Max width 2000mm Every French door we make is manufactured to offer high energy performance with toughened 28mm double glazed, Argon filled Glazed Units. Why buy French doors from us? Mine more resembles the example on the left.. so more of a pointed tip than a groove... I assume both would do the same job..? Or should I look to get another with the grooved tip..?!? The canopy is glazed with 16mm triple wall UV stabilised polycarbonate sheeting offering greater flexibility in canopy design with enhanced strength and rigidity, available in clear, bronze or opal tints.

Threshold: This door comes with a standard point; you can upgrade to Low Aluminium Threshold in the options above. Cill options are available. Applications include: car ports, covered seating areas, covered play areas, porches, patio canopy, caravan cover, cycle/smoking shelters The system is manufactured in maintenance free powder coated aluminium in white as standard with any RAL no. colour available at extra cost and lead time. The red section is the aluminium extension cill with the grey section to the right being a window profile. The light blue sections are the thermally efficient barriers (thermal breaks). Many thanks for taking the time to reply. I think I was somewhat unclear so sorry. I have attached an image to show what I mean more clearly.
