Operation

The lift & slide action of this door is operated by the door handle. When closed (handle pointing up) the door is lowered a few millimeters which compresses the weather-seals, and engages the door into 2 locking points around the frame, for high security and weatherproofing.

 

By turning the handle into the down position, the whole sliding leaf is raised up a few millimeters, releasing the seals and enabling the door to be slid effortlessly along the track.  

 

An internal cylinder lock provides added security. There is a secure ventilation position, and the door can also be lowered at any point along its track to prevent it from moving whilst open by utilising its own weight.

Glazing

Thermo HS products are internally beaded by secret nailing and have profiles that match the Thermo 80 & Elite 92 window systems.

 

In most cases Thermo HS doors are supplied with the glass units temporary beaded into the frame for safe transport, due to weight and handling purposes. The glass is then removed from the frame once at site which makes maneuvering the door around site much easier. Once the door is positioned and fixed into place, the glass units are then placed in the frame and then the glazing beads should be put in place by secret nailing and then siliconed in. 

 

Glazing units can either be double or triple glazed:

Double glazed units; 4–16-4mm with soft-coat low-e and Argon gas filling with a centre-pane u-value of 1.1W/m2K.

Triple glazed units; 4-12-4-12-4mm with soft-coat low-e and Argon gas filling with a centre-pane u-value of 0.7W/m2K.

 

Safety glass is always used in the form of either toughened or laminated for enhanced safety and security.

 

Glazing Bars

 

Structural bars known as transoms (horizontal) or mullions (vertical) are used to separate 2 pieces of glass in either the fixed or sliding sash. When dividing 2 pieces of glass the transom or mullion is 54, 78 or 130mm. Multiple transoms and mullions can be built into 1 frame to create multiple-pane effects to your design requirements, as can decorative glazing bars.

 

Decorative glazing bars are a thinner more elegant solution to those who wish to create a more traditional appearance to their doors and windows. This option includes a 24mm timber glazing bar both internally and externally, with dummy spacer bars between the glass This makes it look like all of the panes created are separated glazed units, as it would have been done traditionally on this design, but without the weakness’ that this creates.

 

Please note that doors supplied with decorative glazing bars must be supplied with glazing fitted at the factory so you must ensure you have adequate handling equipment on site for these weights (please refer to your quotation for the weights of the units).

Accessories

SAA or Bronze anodised Lever handles

SAA or Bronze anodised thermally broken low threshold

Trickle vents to head of sliding sash

Secure ventilation position (standard)

Finish

Frames are supplied pre-assembled, and beautifully finished with a full factory coating from a wide range of stains or paints. 

 

Timber

All timber is finished with a choice of a stains or paints. Paint choices are from the RAL Classic range (approx. 250 colours).

 

All paints and stains that are used are water based micro-porous products from Akzo-Nobel. Actual timber samples are sent out upon receipt of order to help assist in the correct colour choice for your project.

 

It is possible to have a 2 colour system with a different finish from inside to outside, meaning that a solid paint can be used externally and a clear lacquer could be used internally if you wanted to appreciate that natural beauty of the timber without any additional colouring.

 

Aluminium​

Aluminium cladding on the Thermo HS Alu system is polyester powder coated to a choice from the RAL Classic range (approx. 250 colours). As the Thermo HS Alu frames are made up from two components it is standard to have 2 different finishes, i.e. one paint colour externally on the aluminium and a different colour, possibly a stain, internally.
