SUSTAINABILITY

Tiltco has adapted its manufacturing processes to eliminate negative environmental impact through skillful and sensitive production. Tiltco realizes as a manufacturer the responsibilities of creating an energy efficient window to conserve energy and efficiency.

OUR STORY
Tiltco is committed to minimize any negative impacts of our production on the environment. In recognition for environmental management, Tiltco has implemented a recycling program for all aspects of our production waste, facilitating a wide range of technical items to be produced from recycled material. We are currently working with external recycling agencies to process our waste to make sure they do not end up in the wrong place. By reducing toxins and wastes, Tiltco is helping to decrease the effects of climate change.

WHAT IS GREEN?
Being "green can be described as understanding and acting on environmental effects when performing an action. Being "green" does not just apply to individual lifestyles and preferences; however, manufacturing plays a large role in taking this issue forward. This includes using non-toxic materials and eco-friendly production methods which creates an overall healthier atmosphere.

ENVIRONMENTAL BENEFITS
uPVC/vinyl is composed of by weight 57% salt. Although uPVC is manufactured from a naturally abundant material such as salt it can be recycled repeatedly for other building materials. The manufacturing of uPVC/vinyl windows requires two-thirds less energy than aluminum windows thus reducing CO² emissions. This, combined with the lightweight of uPVC/vinyl, requires less energy for transportation. uPVC/vinyl windows are energy-efficient which reduces consumption of heating and cooling energy required by buildings, thus, reducing electricity cost and contributing to environmental design accreditations such as LEED, passive house and net zero housing.

uPVC/VINYL
Unplasticized Polyvinyl Chloride, or uPVC, is odourless, tasteless and has a good chemical resistance. Tiltco uses European uPVC profiles that do not degrade or yellow and offer substantial energy efficiency and greater structural stability. uPVC is commonly referred to as vinyl in North America. uPVC/vinyl is one of the most efficient materials that can be used in manufacturing, especially of windows and doors.

Below are 5 positive reasons why:

1. uPVC/vinyl requires little or no maintenance creating a healthier, cleaner environment by only requiring a mild detergent and water for cleaning.
2. uPVC/vinyl is deployed mainly from natural resources primarily refined oil products and salt.
3. uPVC/vinyl has the lowest production energy and raw material requirements and emissions of any window and door manufacturing process.
4. uPVC/vinyl is a very safe material to construct fenestration products from in that it self extinguishes when in contact with flame.
5. uPVC/vinyl is strictly monitored by manufacturing standards to continually eliminate the negative effects of vinyl production on the environment.

HIGH DURABILITY, LOW MAINTENANCE

Vinyl windows are impervious to rot, rust, corrosion, blistering, flaking, and infestation by termites or other insects. Vinyl resists attacks by fungus and mildew, and scratching a vinyl window will not require any touch-up.

Similarly our wood products require little maintenance compares to other wood joinery products. This is a result of the three steps finishing process which guarantees a few aspects of the finished timber. First, it prevents future deterioration from fungus or rotting. Due to the specific pigmentation of the base coat and finish one achieves a durable finish and a specially high UV durability.

 

WINDOW PERFORMANCE

The performance of a window is essentially a balancing act. the should be designed and installed to allow the maximum amount of solar energy from the sun to pass through into the building interior. They must minimize the amount of heat loss out of the building.

Solar Gain is the positive contribution to the heating of a building interior made by the suns energy passing through the window. Where the windows are situated in the design of the building and the direction it faces is significant to the effect of the solar gain. South facing windows take advantage of the solar grain in the winter because the sun is low in the souther sky. North facing windows will have virtually no exposure to the direct winter sun and are usually net losers of energy. South and west facing windows can cause over heating n summer as a result of unwanted solar gains from the hot afternoon sun.

A simple yet often overlooked factor that affects solar gain is the amount of glazing in the window. A window with a wide frame and numerous small panels divided by nulling and munitions has a much smaller total glazing area to capture solar energy than a window of the same size, but with a narrower frame and single, undivided glazing area. The greater proportion of the glassing to frame area, the greater the amount of sunlight that passes through and the greater the potential for solar gain.

The shading of a window will affect solar gain swell. Roof overhangs and well placed deciduous trees and plants in front of south and west facing windows will protect against over heating in summer but allow beneficial solar gain during the winter months.

 

WINDOW MATERIAL

Once radiation losses are reduced through the use of low-e coatings, convection and conduction losses controlled through the use of gas fills, and conduction heat losses around the edge of the glazed unit reduced via insulating spacers, window frames represent the next potentials weak link in the energy efficiency chain. recognizing that one-third of the overall window is the frame and sash, it is important that they be made to minimize conductive heat loss.

Good frames can be made from any of the materials commonly used such as wood, aluminum, vinyl, fibreglass and so on, as long as the weakness of each are recognized and compensated for.

Frames can also have a significant impact on solar gain. Stronger material allows the frame and the sash to be narrower. This results in more glass area, which increases solar gain and decreases heat loss through productivity. These are called low profile frames and, to date, have achieved the best energy performance ratings.

Aluminum frames and sash are strong, lightweight and durable. in addition to its strength, aluminum is low maintained and resists warping. Aluminum however is a high conductor of heat energy and a significant source of heat loss. to compensate, aluminium frames and sash must incorporate an effective thermal break, such as PVC or urethane, between the inside and outside surfaces to counteract conductive heat loss.

Wood frames and sash are desirable for the natural beauty, good insulating value and structural strength. the do however require significant protection from the elements as well as regular maintenance. Manufacturers are required to treat wood with a preservative to help prevent rotting. Wood frames and sash are often clad on the exterior side with uPVC, aluminum or other factory plied finishes to reduce the maintenance requirements and increase its durability.

Extruded Vinyl or PVC is relatively new and has grown in popularity because its a good thermal performer, lightweight, resistant to the elements and is easy to maintain. Larger windows may not have sufficient structural integrity and must therefrom be reinforced to increase their strength.

Fibreglass is the newest material to be used in a window frame or sash. It is very strong and durable and requires little maintenance. sometimes the hollow core in the frames is filled with foam for even greater thermal performance.

Combination frames and sash combine two or more of the materials described above. the objective is to capitalize on the best features of each material so that the finished product will provide good thermal performance, durability ad strength, and require minimal maintenance.

Composite materials, in contrast to combination frames blend different materials together, such as wood fibres and resins for example, together into a single unified composite material through a manufacturing process. The frames and sash are then manufactured from this unique new material.

HEAT LOSS

It's the basic law of nature that heat energy will move from warmer areas to colder areas. In the context of windows, heat loss is the migration of heat energy from the interior of the building to the exterior through the different components of the window. It occurs in 4 different ways - radiation, conduction, convection and air leakage - and there is no way to avoid it. We can only find ways to slow these processes down.

Radiation losses occur through the window glass and represent about 66% of the total heat loss in a standard window. Ordinary glass readily emits heat energy to colder surfaces so it is said to have emissivity. Technologies to counteract radiation heat loss include low-e, or low emissivity coatings on the glass.

Conduction losses in windows occur primarily through the edges of the glazing through the sash and frames. Advances in glazing unit construction, such as the use of warm edge spacers, and in frame construction such as built-in thermal breaks. Gases other than air, such as argon or krypton, are used to replace air between the panes because they conduct less heat. The optimum space width to minimize heat loss is 1/2" (13mm) for air and argon, while for krypton it is 3/8" (10mm).

Convection losses occur due to air movement between the glazing layers of a window. The convection movement, or rising and falling of the air between the layers of glass as it first warms and then cools, passes heat from the warm interior side to the cooler exterior side.

Air leakage is significant contributor to heat losses. Operable windows usually have more air leakage than fixed windows and most leakage in operable windows occurs between the windows operable sash and frame or the meeting rails of sliding sash.

 

WHAT IS WEATHER STRIPPING?

Weatherstripping is a durable flexible gasket put in place to make an airtight seal between the sash and frame of an operable window when the window is closed. The degree to which an air tight seal is achieved is a function of the type of weatherstripping used and the type of operable window.

Compression seals are seals that can be squeezed tightly together between moving sash and frame. generally speaking, they are the most efficient kind of seals and are most commonly used on casement windows that are pulled shut by means of two or more latches.

Sweep seals is a flexible fin sully made of rubber or polypropylene which is fastened to either the moveable sash or the stationary frame and sweeps against the other component to form a barrier.

Brush seals are most commonly found on sliders to facilitate the sliding movement. It consists of a brush mooted on the moveable sash and the frame.
