NYTROOF Rapid Fit System


NYTROOF is a panelised rapid-fit roof system designed, engineered, and manufactured by NYTimber. Comprised of gable and party spandrels, and pre-insulated structural cassettes, the NYTROOF replaces traditional attic roof trusses in 2.5 and 3 storey dwellings to create a warm room in the roof.

The Rapid Fit System also dramatically increases the speed of build, saving time, money, and reducing risk exposure to construction workers, who are now required to spend much less time working at a height. The pre-fabricated product is delivered to site ready to be craned into position, which eliminates wastage and the need to store materials on-site.

Robust Detail Accreditation

NYTROOF has been designed as a supply only system with on-site simplicity in mind, allowing existing locally employed tradespeople the ownership and ability to fit up to four roofs in one day, with the benefits of off-site fabrication such as dimensional accuracy and guaranteed lead times and delivery days. The NYTRoof Rapid Fit System lives up to its name and is far more efficient than traditional attic trusses and other roofing solutions.

NYTROOF has Robust Detail accreditation.

Roof Windows

Arnold Laver offer a range of roof windows from FAKRO.

Fakro roof windows are made from slow growing, close-grain pine which is guaranteed to be knot-free and of the highest quality. With their handle at the base of the frame, windows provide up to an 8% greater glazing area, letting more light into a room and making windows easier to open.

Fakro windows are available in all the sizes you would expect, even in conservation style, and have a range of flashings for all well-known tiles and slates.

  • topSafe® anti-burglary reinforcement
  • automatic V40P vent as standard
  • 10 year guarantee

Centre pivot windows

Centre pivot windows are the most popular type of FAKRO roof window.

The well-designed centre pivot allows the sash to be opened in a range of positions, thus increasing the amount of fresh air which can be drawn into the room.

The sash can also be rotated through 180° and locked, allowing easy and safe cleaning of the outer pane. The pivot windows are operated using a two-part hinge.

As the air inlet is positioned at the top of the frame, FAKRO windows have a 6% greater surface area when compared with similar sized windows made by other manufacturers. As a result, they maximise the amount of natural light in a room.

Non-standard window specifications, such as windows with automatic air-vents, are available to order:

  • Types FTP-V/H, FTP-V/P are manufactured in pine, vacuum impregnated and coated with acrylic lacquer. The handle is positioned on the lower part of the sash for easy operation, and the window can be secured open in two positions.
  • The windows are suitable for roofs with pitches between 15° and 90° (requires a flashing).
  • A wide range of accessories is also available.
