Installation of doors

Installation of internal door

Installation of internal door is complicated process that requires certain skills and carefulness. Operation of door directly depends on way it is installed. There are some factors to be observed when installing the door, irrespective of whether the door is installed by yourself or by workman.

Preparation to installation

When accepting the door, check if all parts and constitutive elements are present as well as inspect the condition of door and door casing. There must be no defects.

Old door must be demounted carefully without damaging the walls.Working area must be prepared in such a way to provide convenient horizontal positioning of door.

Assembly of door casing

Installation process begins with assembly and mounting of door casing.

It is important to measure dimensions of door aperture correctly and match it to sizes of door casing. Leave 10 mm gap at lower part.

When mounting the casing the upper plate and vertical supports are interfaced. They are perforated in the following places: vertical supports – in the centre of support, the upper plate – in four places within 6 mm from edge.

It is important to install the door exactly perpendicular to floor because it affects the frame ledge of door. In case of incorrect installation the door will either swing open or close time after time.

Corners of casing must be exactly right-angled, otherwise the door can even extend beyond clearance limits of door aperture.

Installation of door

The door is hinged after door casing is assembled and fixed. Pay special attention to selection of door hinges and buy them only from proven sires.

Varadoor recommends to use two loose joint hinges to remove the door without unscrewing of hinges if necessary. Furthermore, these hinges are usually fitted with bearings that ease the stroke of door and extend its service life.

When installing the door leave 1.5 mm gaps between door leaf and door casing lengthwise to open/close the door easily. Temperature and humidity variations can cause extension of door, that’s why the gaps should be no less than 1.5 mm in width.

After hinging check if door closes evenly. If it closes evenly, proceed to next step - acoustic insulation.

Acoustic insulation

Sealing foam is applied between door aperture and door casing to provide acoustic and thermal insulation. Before this work the door is covered with film to protect it from dirt. Door aperture is dampened with water for better contact. Then fine layer of sealing foam is applied throughout the perimeter. Normal amount: 1 gallon per door.

Sealing foam is kept for 12-24 hours (to dry up) for fixing, then excessive parts are removed.

Installation of plat-bands

Plat-bands are matched along the length before installation. Parts of plat-bands are attached to place they will be mounted to. Then plat-bands are lined out and sawed off at 45 degrees. Varadoor recommends the following sequence: left part, upper part, right part.

Then plat-bands are fixed with glue or finishing nails.

Plat-bands hide all probable defects of door installation and considerably improve the appearance of door casing and add completeness to its contruction.

In this article we have described basic stages of door installation work. Pay attention to process of installation because service life of door directly depends on quality of its installation. Correctly installed door is installed for a full due.
