The thermal efficiency benefits of IMC Glass Slim Glaze double glazing can now be even better than standard double glazing, achieving U-values (the term used to measure thermal efficiency) of as low as 1.2 on a 6mm cavity and 1.1 on a 8-cavity, depending on the type of gas fill used in the cavity. The reduction of heat lost through the glass is up to 77% as when compared against single glazing and it is possible on some windows to use Slim- Glaze units to achieve the Part L- building regulations for thermal efficiency.
Inert Heavy Gas
The thermal conductivity properties of krypton and xenon are much lower than air, meaning they are much more efficient insulators and are excellent at reducing U-values in sealed double glazed units. All our slim glazing uses these two gases exclusively, meaning you get excellent insulation against both cold and noise.
Continual condensation can seriously deteriorate the lower sections of a timber frames. Slim Glaze double glazed units will slow down the dew point being reached. The inner pane of the double glazed unit is warmer than the outside pane and our warm edge ‘super spacer’ bar acts as a thermal break, stopping the cold reaching the inner pane of the unit. This helps maintain the room temperature when the heating is switched off at night and thereby reduces condensation and heat loss.

IMC Glass Certification
These are the certificates we hold:
• Certificate BSEN1279 Part 2 BSI 262/4677672 (Production Quality) • Certificate BSEN1279 Part 3 BSI 371/7758378 (Gas Leakage) • Certificate BSEN1279 Part 6 SDG0703/11870B Annex B Audit Test, Declaration Of Performance Number 68603 • Certificate BSEN673 UKAS Certified U-Value (Insulation)
Certification CE and BSEN1279 Approved
To manufacture double glazed units, certification is required for BSEN1279 Part 2, production quality and BSEN1279 Part 3, which relates to gas leakage at less than 1% per annum. Certification is your guarantee of quality and reliability. It is a legal requirement that all double glazed units must have CE mark in accordance with construction products Regulation declaration of performance.
Safety Glass Standards
Safety glass required for all door and sidelights and any glass in a window below 800mm from the floor and can be toughened or laminated glass. Laminate glass has less breaking resistance than toughened glass. Laminated glass will provide protection to internal furnishings as Ultra Violet radiation is reduced by 98/99% and a slightly better acoustic rating. All Double Glazed Units can be constructed with any type of glass or thickness. The width of the cavities determine the insulation or U Value, the thickness of glass has no effect on U Values. All simulations of U-values can be available on request.
Our Safety Glass Standards
• Toughened glass, Class 1 BSEN 12150 • Laminated glass, Class 2 BSEN 14449
• Hodgson Silfix U9 Low moisture Neutral-cure silicon which cures to
form a flexible rubber.
• Hodgson flexistrip a security glazing strip for double-glazing units and laminated glass.
• Hodgson colour glaze putty
• Hodgson multi- purpose putty
• Hodgson butyl 66 Dry seal mp manufactured by repaircare a non-linseed based product manufactured by repair-care which is a durable alternative to putty.
Slim Glaze units to be bedded in back rebate with approximately 2mm of butyl (non-hardening compound) or with flexistrip and centred in rebate with spacers or packers, (the latter not required if using flexistrip) to keep the unit raised from the rebate platform completely fill the void area with silfix silicone and allow to completely cure.
The units can then be putty fronted using one of the above product’s making sure there is full adhesion to the frame and glass and no areas for water to enter the glazing system.
Treat in the same way as above up to the point of putty-fronting. Timber beads to be secured against glass
using nails or screws and sealed with Silfix U9 low moisture Silicone to completely seal any residual voids between glass and rebate and glass and bead. Finish with paint application making contact with glass both inside and outside. It is very important that regular maintenance of the frames and glazing system is undertaken to prevent the access of water into the glazing system.
The major enemy of insulated glass units is water. If water is trapped in contact with the seal of the unit for a period of time, the unit will fail. All glazing systems must protect the edge of the insulated glass unit, either by preventing access of water or by proper drainage and ventilation.
Some silicones are not suitable for use with sealed units. A silicone component (plasticizer) can migrate to the primary seal causing catastrophic failure of the unit, if in doubt please contact your supplier before installing.
Glazing Maintenance Recommendations
Standard units fitted into wooden frames with beads, using non-setting glazing compound and silicone sealant: Where they are surface cracks, loss of adhesion or voids, rake or remove the faulty compound or sealant and replace with
Standard units fitted into frames with beads, using gaskets or mastic load bearing strips: this system is normally used for glazing into aluminium and uPVC window and door frames. Check annually for obvious deterioration and ensure that all drainage holes are free from obstruction.
