Tricept Double Glazed Windows & UPVC Doors...

The first thing to understand about The Tricept Collection is that its products are unlike any other windows, doors, porches and conservatories in terms of their basic construction technology.
Before The Tricept Collection, if you happened to live in a beautifully renovated country cottage, you’d probably have to accept the same window and door frame style as someone who lived in a stylish ultra-modern town house.
That’s because most ordinary frames are manufactured with square, straight edged profiles. They all tend to look very similar. So, too many homes have had to settle for ‘me too’ double glazed windows and doors that lack any real personality.

For the best glazing on the Planet - South Lakes Windows Ltd can help!
What The Tricept Collection has done is to take PVCu, an innovative frame material, a material that can look and feel as warm and full of character as wood, and shape it into a range of unique, individual styles.
The Tricept Collection offers you a whole palette of sculptured and chamfered profiles, a complete spectrum capable of complementing, enhancing or transforming everyone's dream for every style of home. (The Tricept collection is an advancement on The Ultimate Collection which came before.)

Ultimate UPVC Performance...
The Tricept collection from South Lakes Windows Ltd is PVC-u that is crafted to give all the warmth, character and flexibility of a natural wood frame.
But what is even more vital than the ways in which our PVCu double glazed windows and composite doors are similar to wood, are the ways in which it can actually perform better than wood.
Wood rots and decays. It also splinters. It gets damp. It needs painting. It needs year-after-year care and maintenance. Gaps appear. Wooden window frames need replacing or repairing.
The Tricept Collection u-PVC won’t rot. Or fade or ever need painting. Or ever need care apart from a wipe with a damp cloth.
It will stay looking as good as the day it was installed.
On top of this there’s the actual glazing technology...
All our low emissivity (LOW ‘E’) sealed window units, use glass complying with the new Document L of the building regulations.
This is part of a government initiative to cut heat loss from buildings, ensuring that your home heating system functions at maximum efficiency and therefore reduces carbon emissions into the atmosphere.

uPVC Thermal Enhancement
To maximise thermal performance new Tricept PVC-u is engineered from 70mm wide profile (The industry maximum). Innovative outer frame thermal PVC-u reinforcing ensures optimum energy efficiency with a minimum of 7 vertical chambers helping to resist outside temperatures and retain internal warmth within your home.
This new windows and doors frame technology results in far greater heat retention and continues to meet all the requirements achieved by conventional hollow metal frame reinforcing.


Top Grade PVC-U
European standards state that Grade A PVC-U must have an outside wall thickness of at least 2.8mm
Tricept wall thickness is 3mm which offers superb replacement window frame and PVC-u door strength and rigidity that will last for years!
Weather Resistance
You should expect your new upvc replacement windows and upvc doors to be completely draught proof and water tight. New Tricept is produced with all weather compression gaskets, fused to both the inner and outer window frame sections. The gaskets include a 9mm "flipper seal and backing cushion" to ensure ultimate weather resistance and sealed unit stability. The flipper seal remains inline with the profile for a neater appearance and because they are fused to the profile they can never shrink back thus avoiding any window leaks or irritating window draughts in your home. Repairing steamed up windows is a thing of the past with Tricept!
Integral Drainage
To enhance weather resistance further Tricept has a sophisticated "built in" sloping drainage system that directs any water penetration away and towards the external drainage route. Definitely no steamy windows!

Neat uPVC Window Installation
To ensure your new replacement windows are fitted neat and square, and to prevent "window bowing" upon installation, two 8mm legs have been added to the brick facing edge of the window profile to provide a solid fixing.
Correct Window Glazing
In order to avoid the breakdown of double glazed units it is essential that your glazing unit remains in dry conditions at all times.
Tricept have designed a unique glazing packer (1) that is sprung in place for the glazed unit (2) to sit on and therefore create a bridge between the sealed unit and any water or dampness thus preventing steamy condensation forming inside your double glazed windows.

Window Frame Versatility
Whilst all the profiles remain technically the same, Tricept offer you a choice of either a fully bevelled system or fully Ovolo depending on your preference.
Unique in design, the Ovolo "Royale" system features a sculptured style of window offering you softer curved lines that complement every type of home be it terraced, semi-detached, detached, modern or period property.
The bevelled design is a fully chamfered style of window designed to recreate the traditional putty lines of timber profiles. The sleek modern lines will suit any home particularly contemporary designs.
70mm profile (Quicker install)
The window frame profile measures 70mm front to back, to ensure a direct replacement with timber windows with minimal trimming or finishing allowing for a quicker install of your upvc replacement windows.
Clean Lines
Both glazing systems have been designed to be symmetrically correct in that all flat surfaces are similar in width which in essence offers a far slimmer and more aesthetically pleasing appearance to your new window.
