Window Replacement For Motorhomes. If you own a motorhome, caravan, horse box or camper and would like to replace an existing window or fit a new one then we can supply a complete window kit in various sizes with both hinged or sliding options. Our windows are easy to install making them perfect for both DIY enthusiasts and professional window fitters alike. They are supplied in two parts, one for the exterior and one for the interior. The exterior has an aluminium frame, stainless steel supports and features grey tinted double acrylic glazing; whilst the interior is white and cream with an integrated roller blind and fly screen. For added security our windows have multiple catches and locks, that when used correctly, can prevent your window from being opened from the outside. These windows are ideal for new vehicles as well as retro fitting onto an older vehicle. Screw interior and exterior window frames together from inside the vehicle. This will clamp the interior and exterior window frames to the wall of the vehicle. The interior cassette will then fit to the interior window frame. Create a water tight seal by applying a sealant around the outer frame. If in doubt, always seek professional assistance. Please ensure measurements will suit your requirements. The sliding windows suit walls with a thickness of 30MM, and the hinged windiws suit a wall thickness of 22MM – 35MM.
